Telephone numbers in the Philippines
Telephone numbers in the Philippines follow an open telephone numbering plan and an open dial plan. Both plans are regulated by the National Telecommunications Commission, an agency under the Department of Information. The Philippines is assigned an international dialling code of 63 by ITU-T, telephone numbers are fixed at seven digits, with area codes fixed at one, two, or three digits. Mobile phone numbers are always 10 digits, when making long-distance calls in the Philippines, the prefix 0 for domestic calls and 00 for international calls are used. Some smaller carriers concentrated within a geographic area may issue four- or five-digit area codes. Occasionally, an area may change area codes. For example, the City of Bacoor in Cavite has been included in the coverage area of area code 2 per the National Telecommunications Commissions Memorandum Order No. 08-09-2011, although almost all fixed-lines in the city use the old 46 area code due to the poor compliance of PLDT. Sometimes area codes are shared by a number of government entities to maximise their use.
In extreme cases, area codes are shared across an island like in Leyte and Samar, or even entire regions, in order to identify the calls point of origin, the three-digit telephone exchange prefix is checked. Since the Philippines employs an open plan, telephone numbers dialled within a given area code do not require the area code. When dialling other area codes, the long distance access prefix 0 is added, but when dialling from overseas. However, the code indicates the service provider and not necessarily a geographic region. Unlike fixed-line telephones, the telephone dialling format is always observed when using a mobile phone. Therefore, mobile phone numbers always have the format +63 xxx-xxxx for international callers and 0 xxx-xxxx for domestic callers. Some of the first area codes to be assigned for mobile phones were 912 for Mobiline/Piltel,915 for Islacom,917 for Globe Telecom,918 for Smart Communications, and 973 for Express Telecom. As service began growing rapidly since the 1990s, new codes have been added to meet demand as existing codes have since been exhausted, newer codes often come immediately after the last code exhausted, but this might not be the case if the next code is already in use.
955/956 are the latest codes and are used for Globe & TM, areas codes are grouped by provider with no single contiguous block of codes for a single provider

Telephone numbers in Kazakhstan
Telephone numbers in Kazakhstan are under a unified numbering plan with Russia with the country calling code +7. Historically, +7 was used as the Soviet Union country calling code, following the break-up of the Soviet Union, all former republics except Russia and Kazakhstan switched to new country codes. As in Russia, Kazakhstan employs a four-level open dialing plan, the international dialing prefix is 8~10 - callers dial 8, wait for a tone, and dial 10, followed by the country code, area code and number. The long distance dialing prefix is 8 - callers dial 8, wait for a tone, under an agreement with Russia on 11 June 2006, Kazakhstan is assigned zone codes 6xx and 7xx under the unified plan. Land lines are in zone codes from 710 to 729, mobiles are in zone codes 70x and 77x. Previously, land lines used zone codes in the 3xx range, as zone codes 3xx are assigned to Russia, zone codes 3xx in Kazakhstan were changed by substituting the leading 3 with 7
Telephone numbers in China
Land lines and mobile telephone numbers have different structures, land lines use area codes, while mobile phones do not. Land line phone numbers in cities have 8 digits after the two digit area code, whereas in other areas no less than 7 digits after a three digit area code. Mobile phone numbers have 11 digits without area codes, dialing a land line from another land line within the same area does not require dialing the area code. When making a long distance call from a land line phone, the trunk prefix 0 must be dialed first, followed by the area code. Calling a mobile phone from a land line requires the addition of the 0 in front of the phone number if they are not in the same area as well. Mobile to land line calls require the 0 and the area code, Mobile to mobile calls does not require the 0. The 0 is never needed when dialing from outside mainland China, the Special Administrative Regions of Hong Kong and Macau are not part of this numbering plan, and use the country codes +852 and +853, respectively.
In addition, the PRC numbering plan reserves space for Taiwan, PRC claims Taiwan and several islands off Fujian which are under the control of the Republic of China. Currently phone numbers in these areas are under the international calling code of +886. In mainland China, mobile numbers have 11 digits in the format 1xx-xxxx-xxxx. As the fourth digit was introduced later, thus it is 0 for all old numbers, in further extensions, non-139,138,130 numbers were introduced. The fifth to seventh digit sometimes relates to age and location, even earlier, before GSM age, mobile phones had numbers starting with 9. Those numbers were eventually translated into 1390xx9…, where xx were local identifiers, Mobile service providers can be identified by the first three or four digits as follows, * Formerly China Unicom Note,170 and 171, are allocated to Mobile virtual network operator. Beijing –10 These are area codes for the municipalities of Shanghai and Chongqing, all of these cities have upgraded to an 8-number system in the past decade.

Additionally, numbers starting 400 are shared-pay numbers, the provincial capital and Tieling, Benxi, uses code 24. The provincial capital of Nanjing uses code 25, all telephone numbers are 8-digit in Jiangsu. All area codes with prefix 6 were assigned in recent years and this prefix was reserved for Taiwan during the cold war years
