Lancaster is a charter city in northern Los Angeles County, in the Antelope Valley of the western Mojave Desert in Southern California. As of 2013, Lancaster was the 31st largest city in California. Lancaster is part of a twin city complex with its southern neighbor Palmdale and together they are the principal cities within the Antelope Valley region. Lancaster is located 61 miles north of downtown Los Angeles, near the Kern County line, it is separated from the Los Angeles Basin by the San Gabriel Mountains to the south, from Bakersfield and the San Joaquin Valley by the Tehachapi Mountains to the north. The population of Lancaster grew from 37,000 at the time of its incorporation in 1977 to over 156,000 in 2010. According to the Greater Antelope Valley Economic Alliance report of 2015, Lancaster has a population of 168,049; the area where Lancaster is now located, known as the Antelope Valley, was home to the Paiute Indians. Lancaster's origins as a settlement start with the Southern Pacific Railroad, believed to first use the name Lancaster, where a station house, locomotive watering facilities and section gang housing were built when the railroad laid track through the town's future location.
In 1876 the Southern Pacific completed the line through the Antelope Valley, linking San Francisco and Los Angeles. The origin of Lancaster's name is unclear, attributed variously to the surname of a railroad station clerk, the moniker given by railroad officials, or the former Pennsylvania home of unknown settlers. Train service brought passengers through the water-stop-turned-community, with the help of promotional literature, attracted new settlers; the person credited with formally developing the town is Moses Langley Wicks, who in 1884 bought property from the railroad for $2.50 per acre, mapped out a town with streets and lots, by September was advertising 160-acre tracts of land for $6 an acre. The following year, the Lancaster News started publication, making it the first weekly newspaper in the Antelope Valley. By 1890, Lancaster was bustling and booming, thanks to adequate rainfall, farmers planted and sold thousands of acres of wheat and barley; the town was devastated by the decade-long drought that began in 1894, killing businesses and driving cattle north, though fortunes improved somewhat in 1898 following the nearby discoveries of gold and borax, the latter to become a widespread industrial chemical and household cleaner.
Thanks to the five-year construction of the 233-mile Los Angeles Aqueduct starting in 1908, Lancaster became a boom town by housing aqueduct workers. The 1912 completion of Antelope Valley Union High School allowed students from the growing region to study locally instead of moving to distant cities, the school boasted the state's first dormitory system to accommodate students from outlying districts; the community began a steady growth spurt in the 1930s, starting with construction of Muroc Air Force Base, site of frequent flight tests, including the "breaking" of the sound barrier by Chuck Yeager in a Bell X-1A in 1947. In the 1980s through the end of the program, Edwards Air Force Base, by renamed, hosted a limited number of landings of the Space Shuttle; the development of Air Force Plant 42 in 1958, augmented in the 1960s by construction of Lockheed Aircraft's Plant 10, created tens of thousands of jobs. High-wage employment hit its peak in the 1970s during the Lockheed L-1011 commercial wide body jetliner project, for which all assembly and some engineering and parts production were performed.
250 L-1011 aircraft were airfield. Lancaster was an unincorporated community in Los Angeles County until 1977, when it was incorporated as a city, with Arnold Rodio serving as its first mayor. Lancaster State Prison opened in 1993 and before that Los Angeles County hosted no prisons but accounted for forty percent of California's state-prison inmates. "Most of Lancaster's civic leaders and residents" opposed the building of the prison, four inmates escaped from LAC in its first year of operation. By 2000 a proposal to increase the proportion of maximum-security inmates received little criticism. In 2005, Hyundai Motor Co. announced the grand opening of a 4,300-acre, $60 million "Proving Ground," a state-of-the-art testing facility for cars and sports utility vehicles in nearby California City. Lancaster is now home to major defense contractors such as Boeing, Northrop Grumman, Lockheed Martin, BAE, government agencies, such as the NASA Dryden Flight Research Center, which are all active in design and manufacturing of a variety of military and commercial equipment.
Notable projects assembled and/or designed there include the Space Shuttle orbiters, B-1 Lancer bomber, B-2 Spirit bomber, F-117 Nighthawk fighter, F-35 Joint Strike Fighter, the Lockheed L-1011 TriStar, a wide body passenger jet aircraft. The region is proximate to the Mojave Air & Space Port, famous as the base of operations for Virgin Galactic and Scaled Composites, the company that designed SpaceShipOne and won the X-Prize. In 2010, the city opened The BLVD, a one-mile revitalized stretch of Lancaster Boulevard between 10th Street West and Sierra Highway. City leaders have set the ambitious goal of becoming the nation's first Net-Zero municipality, wherein they will produce more clean energy than they consume. Much of the city's infrastructure including City Hall, local schools, their minor league baseball stadium are solar powered. In March 2013, Lancaster became the first city in the US to require solar panels on all new homes in an effort to make the community more carbon neutral; the rule took effect in January, 2014.

Marriage called matrimony or wedlock, is a or ritually recognised union between spouses that establishes rights and obligations between those spouses, as well as between them and any resulting biological or adopted children and affinity. The definition of marriage varies around the world not only between cultures and between religions, but throughout the history of any given culture and religion, evolving to both expand and constrict in who and what is encompassed, but it is principally an institution in which interpersonal relationships sexual, are acknowledged or sanctioned. In some cultures, marriage is recommended or considered to be compulsory before pursuing any sexual activity; when defined broadly, marriage is considered a cultural universal. A marriage ceremony is known as a wedding. Individuals may marry for several reasons, including legal, libidinal, financial and religious purposes. Whom they marry may be influenced by gender determined rules of incest, prescriptive marriage rules, parental choice and individual desire.
In some areas of the world, arranged marriage, child marriage and sometimes forced marriage, may be practiced as a cultural tradition. Conversely, such practices may be outlawed and penalized in parts of the world out of concerns of the infringement of women's rights, or the infringement of children's rights, because of international law. Around the world in developed democracies, there has been a general trend towards ensuring equal rights within marriage for women and recognizing the marriages of interfaith and same-sex couples; these trends coincide with the broader human rights movement. Marriage can be recognized by a state, an organization, a religious authority, a tribal group, a local community, or peers, it is viewed as a contract. When a marriage is performed and carried out by a government institution in accordance with the marriage laws of the jurisdiction, without religious content, it is a civil marriage. Civil marriage recognizes and creates the rights and obligations intrinsic to matrimony before the state.
When a marriage is performed with religious content under the auspices of a religious institution it is a religious marriage. Religious marriage recognizes and creates the rights and obligations intrinsic to matrimony before that religion. Religious marriage is known variously as sacramental marriage in Catholicism, nikah in Islam, nissuin in Judaism, various other names in other faith traditions, each with their own constraints as to what constitutes, who can enter into, a valid religious marriage; some countries do not recognize locally performed religious marriage on its own, require a separate civil marriage for official purposes. Conversely, civil marriage does not exist in some countries governed by a religious legal system, such as Saudi Arabia, where marriages contracted abroad might not be recognized if they were contracted contrary to Saudi interpretations of Islamic religious law. In countries governed by a mixed secular-religious legal system, such as in Lebanon and Israel, locally performed civil marriage does not exist within the country, preventing interfaith and various other marriages contradicting religious laws from being entered into in the country, civil marriages performed abroad are recognized by the state if they conflict with religious laws.
The act of marriage creates normative or legal obligations between the individuals involved, any offspring they may produce or adopt. In terms of legal recognition, most sovereign states and other jurisdictions limit marriage to opposite-sex couples and a diminishing number of these permit polygyny, child marriages, forced marriages. In modern times, a growing number of countries developed democracies, have lifted bans on and have established legal recognition for the marriages of interfaith and same-sex couples; some cultures allow the dissolution of marriage through annulment. In some areas, child marriages and polygamy may occur in spite of national laws against the practice. Since the late twentieth century, major social changes in Western countries have led to changes in the demographics of marriage, with the age of first marriage increasing, fewer people marrying, more couples choosing to cohabit rather than marry. For example, the number of marriages in Europe decreased by 30% from 1975 to 2005.
In most cultures, married women had few rights of their own, being considered, along with the family's children, the property of the husband. In Europe, the United States, other places in the developed world, beginning in the late 19th century and lasting through the 21st century, marriage has undergone gradual legal changes, aimed at improving the rights of the wife; these changes included giving wives legal identities of their own, abolishing the right of husbands to physically discipline their wives, giving wives property rights, liberalizing divorce laws, providing wives with reproductive rights of their own, requiring a wife's consent when sexual relations occur. These changes have occurred in Western countries. In the 21st century, there continue to be controversies regarding the legal status of married women, legal acceptance of or leniency towards violence within marriage, traditional marriage customs such as dowry and bride price, for
United States Census Bureau
The United States Census Bureau is a principal agency of the U. S. Federal Statistical System, responsible for producing data about the American people and economy; the Census Bureau is part of the U. S. Department of Commerce and its director is appointed by the President of the United States; the Census Bureau's primary mission is conducting the U. S. Census every ten years, which allocates the seats of the U. S. House of Representatives to the states based on their population; the Bureau's various censuses and surveys help allocate over $400 billion in federal funds every year and it helps states, local communities, businesses make informed decisions. The information provided by the census informs decisions on where to build and maintain schools, transportation infrastructure, police and fire departments. In addition to the decennial census, the Census Bureau continually conducts dozens of other censuses and surveys, including the American Community Survey, the U. S. Economic Census, the Current Population Survey.
Furthermore and foreign trade indicators released by the federal government contain data produced by the Census Bureau. Article One of the United States Constitution directs the population be enumerated at least once every ten years and the resulting counts used to set the number of members from each state in the House of Representatives and, by extension, in the Electoral College; the Census Bureau now conducts a full population count every 10 years in years ending with a zero and uses the term "decennial" to describe the operation. Between censuses, the Census Bureau makes population projections. In addition, Census data directly affects how more than $400 billion per year in federal and state funding is allocated to communities for neighborhood improvements, public health, education and more; the Census Bureau is mandated with fulfilling these obligations: the collecting of statistics about the nation, its people, economy. The Census Bureau's legal authority is codified in Title 13 of the United States Code.
The Census Bureau conducts surveys on behalf of various federal government and local government agencies on topics such as employment, health, consumer expenditures, housing. Within the bureau, these are known as "demographic surveys" and are conducted perpetually between and during decennial population counts; the Census Bureau conducts economic surveys of manufacturing, retail and other establishments and of domestic governments. Between 1790 and 1840, the census was taken by marshals of the judicial districts; the Census Act of 1840 established a central office. Several acts followed that revised and authorized new censuses at the 10-year intervals. In 1902, the temporary Census Office was moved under the Department of Interior, in 1903 it was renamed the Census Bureau under the new Department of Commerce and Labor; the department was intended to consolidate overlapping statistical agencies, but Census Bureau officials were hindered by their subordinate role in the department. An act in 1920 changed the date and authorized manufacturing censuses every two years and agriculture censuses every 10 years.
In 1929, a bill was passed mandating the House of Representatives be reapportioned based on the results of the 1930 Census. In 1954, various acts were codified into Title 13 of the US Code. By law, the Census Bureau must count everyone and submit state population totals to the U. S. President by December 31 of any year ending in a zero. States within the Union receive the results in the spring of the following year; the United States Census Bureau defines four statistical regions, with nine divisions. The Census Bureau regions are "widely used...for data collection and analysis". The Census Bureau definition is pervasive. Regional divisions used by the United States Census Bureau: Region 1: Northeast Division 1: New England Division 2: Mid-Atlantic Region 2: Midwest Division 3: East North Central Division 4: West North Central Region 3: South Division 5: South Atlantic Division 6: East South Central Division 7: West South Central Region 4: West Division 8: Mountain Division 9: Pacific Many federal, state and tribal governments use census data to: Decide the location of new housing and public facilities, Examine the demographic characteristics of communities and the US, Plan transportation systems and roadways, Determine quotas and creation of police and fire precincts, Create localized areas for elections, utilities, etc.
Gathers population information every 10 years The United States Census Bureau is committed to confidentiality, guarantees non-disclosure of any addresses or personal information related to individuals or establishments. Title 13 of the U. S. Code establishes penalties for the disclosure of this information. All Census employees must sign an affidavit of non-disclosure prior to employment; the Bureau cannot share responses, addresses or personal information with anyone including United States or foreign government
San Gabriel Mountains
The San Gabriel Mountains are a mountain range located in northern Los Angeles County and western San Bernardino County, United States. The mountain range is part of the Transverse Ranges and lies between the Los Angeles Basin and the Mojave Desert, with Interstate 5 to the west and Interstate 15 to the east; this range lies in, is surrounded by, the Angeles National Forest, with the San Andreas Fault as the northern border of the range. The highest peak in the range is Mount San Antonio referred to as Mt. Baldy. Mount Wilson is another famous peak, famed for the Mount Wilson Observatory and the antenna farm that houses many of the transmitters for local media; the observatory may be visited by the public. On October 10, 2014, President Obama designated the area the San Gabriel Mountains National Monument. To date, The Trust for Public Land has protected more than 3,800 acres of land in the San Gabriel Mountains, its foothills and the Angeles National Forest. Much of the range features rolling peaks.
The range lacks craggy features, but contains a large number of canyons and is very rugged and difficult to traverse. The San Gabriel Mountains are in effect a large fault block, uplifted and dissected by numerous rivers and washes; the highest elevation, Mount San Antonio at 10,064 feet, rises towards the eastern extremity of the range which extends from the Cajon Pass on the east, where the San Gabriel Mountain Range meets the San Bernardino Mountain Range, westward to meet the Santa Susanna range at Newhall Pass. North of San Fernando, the San Gabriel Mountains crest abruptly up to 4,000 feet. Pacoima and Big Tujunga Canyons cut through the range just east of San Fernando, carrying runoff into the San Fernando Valley. Little Tujunga Canyon Road bridges the range in this area, connecting the San Fernando Valley to the Santa Clara River valley in the north. Towering over Big Tujunga Canyon north of Big Tujunga Reservoir is Mount Gleason, which at 6,502 feet, is the highest in this region of the San Gabriels.
South of the gorge are the southern "foothills" of the mountains, which rise abruptly 4,000 feet above the Los Angeles Basin and give rise to the Arroyo Seco, a tributary of the Los Angeles River. Southeast of Big Tujunga Canyon, the southern front range of the San Gabriels grows in elevation, culminating in notable peaks such as Mount Wilson at 5,710 feet. On the north the range is abruptly dissected by the canyon of the West Fork San Gabriel River. Further north the range slopes up into the towering main crest of the San Gabriels, a sweeping arc-shaped massif 30 miles in length that includes most of the highest peaks in the range: Waterman Mountain, at 8,038 feet. On the north slopes of the San Gabriel crest, the northern ranks of mountains drop down incrementally to the floor of the Mojave Desert in a much more gradual manner than the sheer southern flank; the Angeles Crest Highway, one of the main routes across the San Gabriels, runs through this area from west to east. Little Rock, Big Rock and Sheep Creeks drain off the northern part of the mountains, forming large alluvial fans as they descend into the Mojave.
To the east, the San Andreas Fault cuts across the range, forming a series of long and narrow depressions, including Swarthout Valley and Lone Pine Canyon. South of Mount San Antonio, San Antonio Creek drains the mountains, cutting the deep San Antonio Canyon. East of San Antonio Canyon, the range loses elevation, the highest peaks in this section of the mountain range are in the south, rising above the Inland Empire cities of Claremont and Rancho Cucamonga. However, there are still several notable peaks in this region, including Telegraph Peak, at 8,985 feet, Cucamonga Peak, at 8,859 feet, Ontario Peak, rising 8,693 feet. Lytle Creek, flowing southeast, drains most of the extreme eastern San Gabriels; the range terminates at Cajon Pass, through which runs Interstate 15, beyond which rise the higher San Bernardino Mountains. The Range is bound on the north by the Antelope Valley and the Mojave Desert and to the south by the communities of greater Los Angeles area. In the western portion of the San Gabriel Mountain Range, the Sierra Pelona Ridge stretches from Soledad Canyon, formed by the Santa Clara River.
The Sierra Pelona Ridge includes Liebre Mountain, Sawmill Mountain, Grass Mountain, Redrock Peak, Burnt Peak, most of, part of the Angeles National Forest, but features several rural communities. Melting snow and rain runoff on the south side of the San Gabriels' highest mountains give rise to its largest river, the San Gabriel River. Just to the west of Mount Hawkins, a north-south divide separates water running down the two main forks of the river and their tributaries; the West Fork, beginning at Red Box Saddle, runs 14 miles eastward, the East Fork, starting north of Mount San Antonio, flows 18 miles south and west through a steep and precipitous gorge. The two meet at San Gabriel Reservoir, turn south, boring through the southern portion of the San Gabriels, emptying out of the mountains near Azusa into the urban San Gabriel Valley, to the Pacific Ocean near Seal Beach. San Gabriel Mountains peaks within the Angeles National Forest include: Mount San Antonio, 10,064 ft Pine Mountain, 9,648 ft Dawson Peak, 9,575 ft
The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
Los Angeles County, California
Los Angeles County the County of Los Angeles, in the Los Angeles metropolitan area of the U. S. state of California, is the most populous county in the United States, with more than 10 million inhabitants as of 2017. As such, it is the largest non–state level government entity in the United States, its population is larger than that of 41 individual U. S. states. It is the third-largest metropolitan economy in the world, with a Nominal GDP of over $700 billion—larger than the GDPs of Belgium and Taiwan, it has 88 incorporated cities and many unincorporated areas and, at 4,083 square miles, it is larger than the combined areas of Delaware and Rhode Island. The county is home to more than one-quarter of California residents and is one of the most ethnically diverse counties in the U. S, its county seat, Los Angeles, is California's most populous city and the nation's second largest city with about 4 million people. Los Angeles County is one of the original counties of California, created at the time of statehood in 1850.
The county included parts of what are now Kern, San Bernardino, Inyo, Tulare and Orange counties. In 1851 and 1852, Los Angeles County stretched from the coast to the border of Nevada; as the population increased, sections were split off to organize San Bernardino County in 1853, Kern County in 1866, Orange County in 1889. Prior to the 1870s, Los Angeles County was divided into townships, many of which were amalgamations of one or more old ranchos, they were: Azusa El Monte Azusa and El Monte Townships were merged for the 1870 census. City of Los Angeles Los Angeles Township Los Nietos San Jose San Gabriel Santa Ana. For the 1870 census, Annaheim district was enumerated separately. San Juan. San Pedro. Tejon When Kern County was formed, the portion of the township remaining in Los Angeles County became Soledad Township According to the U. S. Census Bureau, the county has an area of 4,751 square miles, of which 4,058 square miles is land and 693 square miles is water. Los Angeles County borders 70 miles of coast on the Pacific Ocean and encompasses mountain ranges, forests, lakes and desert.
The Los Angeles River, Rio Hondo, the San Gabriel River and the Santa Clara River flow in Los Angeles County, while the primary mountain ranges are the Santa Monica Mountains and the San Gabriel Mountains. The western extent of the Mojave Desert begins in the Antelope Valley, in the northeastern part of the county. Most of the population of Los Angeles County is located in the south and southwest, with major population centers in the Los Angeles Basin, San Fernando Valley and San Gabriel Valley. Other population centers are found in the Santa Clarita Valley, Pomona Valley, Crescenta Valley and Antelope Valley; the county is divided west-to-east by the San Gabriel Mountains, which are part of the Transverse Ranges of southern California, are contained within the Angeles National Forest. Most of the county's highest peaks are in the San Gabriel Mountains, including Mount San Antonio 10,068 feet ) at the Los Angeles-San Bernardino county lines, Mount Baden-Powell 9,399 feet, Mount Burnham 8,997 feet and Mount Wilson 5,710 feet.
Several lower mountains are in the northern and southwestern parts of the county, including the San Emigdio Mountains, the southernmost part of Tehachapi Mountains and the Sierra Pelona Mountains. Los Angeles County includes San Clemente Island and Santa Catalina Island, which are part of the Channel Islands archipelago off the Pacific Coast. East: Eastside, San Gabriel Valley, portions of the Pomona Valley West: Westside, Beach Cities South: South Bay, South Los Angeles, Palos Verdes Peninsula, Gateway Cities, Los Angeles Harbor Region North: San Fernando Valley, Crescenta Valley, portions of the Conejo Valley, portions of the Antelope Valley and Santa Clarita Valley Central: Downtown Los Angeles, Mid-Wilshire, Northeast Los Angeles Angeles National Forest Los Padres National Forest Santa Monica Mountains National Recreation Area Los Angeles County had a population of 9,818,605 in the 2010 United States Census; the racial makeup of Los Angeles County was 4,936,599 White, 1,346,865 Asian, 856,874 African American, 72,828 Native A
A ZIP Code is a postal code used by the United States Postal Service in a system it introduced in 1963. The term ZIP is an acronym for Zone Improvement Plan; the basic format consists of five digits. An extended ZIP+4 code was introduced in 1983 which includes the five digits of the ZIP Code, followed by a hyphen and four additional digits that reference a more specific location; the term ZIP Code was registered as a servicemark by the U. S. Postal Service, but its registration has since expired; the early history and context of postal codes began with postal district/zone numbers. The United States Post Office Department implemented postal zones for numerous large cities in 1943. For example: The "16" was the number of the postal zone in the specific city. By the early 1960s, a more organized system was needed, non-mandatory five-digit ZIP Codes were introduced nationwide on July 1, 1963; the USPOD issued its Publication 59: Abbreviations for Use with ZIP Code on October 1, 1963, with the list of two-letter state abbreviations which are written with both letters capitalized.
An earlier list in June had proposed capitalized abbreviations ranging from two to five letters. According to Publication 59, the two-letter standard was "based on a maximum 23-position line, because this has been found to be the most universally acceptable line capacity basis for major addressing systems", which would be exceeded by a long city name combined with a multi-letter state abbreviation, such as "Sacramento, Calif." along with the ZIP Code. The abbreviations have remained unchanged, with the exception of Nebraska, changed from NB to NE in 1969 at the request of the Canadian postal administration, to avoid confusion with the Canadian province of New Brunswick. Robert Moon is considered the father of the ZIP Code; the post office only credits Moon with the first three digits of the ZIP Code, which describe the sectional center facility or "sec center." An SCF is a central mail processing facility with those three digits. The fourth and fifth digits, which give a more precise locale within the SCF, were proposed by Henry Bentley Hahn Sr.
The SCF sorts mail to all post offices with those first three digits in their ZIP Codes. The mail is sorted according to the final two digits of the ZIP Code and sent to the corresponding post offices in the early morning. Sectional centers do not deliver mail and are not open to the public, most of their employees work the night shift. Mail picked up at post offices is sent to their own SCF in the afternoon, where the mail is sorted overnight. In the case of large cities, the last two digits coincide with the older postal zone number thus: In 1967, these became mandatory for second- and third-class bulk mailers, the system was soon adopted generally; the United States Post Office used a cartoon character, which it called Mr. ZIP, to promote the use of the ZIP Code, he was depicted with a legend such as "USE ZIP CODE" in the selvage of panes of postage stamps or on the covers of booklet panes of stamps. In 1971 Elmira Star-Gazette reporter Dick Baumbach found out the White House was not using a ZIP Code on its envelopes.
Herb Klein, special assistant to President Nixon, responded by saying the next printing of envelopes would include the ZIP Code. In 1983, the U. S. Postal Service introduced an expanded ZIP Code system that it called ZIP+4 called "plus-four codes", "add-on codes", or "add-ons". A ZIP+4 Code uses the basic five-digit code plus four additional digits to identify a geographic segment within the five-digit delivery area, such as a city block, a group of apartments, an individual high-volume receiver of mail, a post office box, or any other unit that could use an extra identifier to aid in efficient mail sorting and delivery. However, initial attempts to promote universal use of the new format met with public resistance and today the plus-four code is not required. In general, mail is read by a multiline optical character reader that instantly determines the correct ZIP+4 Code from the address—along with the more specific delivery point—and sprays an Intelligent Mail barcode on the face of the mail piece that corresponds to 11 digits—nine for the ZIP+4 Code and two for the delivery point.
For Post Office Boxes, the general rule is. The add-on code is one of the following: the last four digits of the box number, zero plus the last three digits of the box number, or, if the box number consists of fewer than four digits, enough zeros are attached to the front of the box number to produce a four-digit number. However, there is no uniform rule, so the ZIP+4 Code must be looked up individually for each box; the ZIP Code is translated into an Intelligent Mail barcode, printed on the mailpiece to make it easier for automated machines to sort. A barcode can be printed by the sender, it is better to let the post office put one on. In general, the post office uses OCR technology, though in some cases a human might have to read and enter the address. Customers who send bulk mail can get a discount on postage if they have printed the barcode themselves and have presorted the mai
