FedEx Corporation, formerly Federal Express Corporation and later FDX Corporation, is an American multinational conglomerate holding company focused on transportation, e-commerce and business services based in Memphis, Tennessee. The name "FedEx" is a syllabic abbreviation of the name of the company's original air division, Federal Express, which was used from 1973 until 2000. FedEx today is best known for its air delivery service, FedEx Express, which was one of the first major shipping companies to offer overnight delivery as a flagship service. Since then, FedEx also started FedEx Ground, FedEx Office, FedEx Supply Chain, FedEx Freight, and various other services across multiple subsidiaries, often meant to respond to its main competitor, UPS. The company is the fifth largest American-headquartered employer globally with 547,000 employees, and FedEx is also one of the top contractors of the US government and assists in the transport of some United States Postal Service packages through their Air Cargo Network contract.

Package delivery or parcel delivery is the delivery of shipping containers, parcels, or high-value mail as single shipments. The service is provided by most postal systems, express mail, private courier companies, and less-than-truckload shipping carriers. Package delivery is different in each country, and how packages are delivered is closely connected with the cost for delivering to that country as well as population. In 2019, China, The United States, and Japan were the leaders in package delivery while Latvia, Macau, and Iceland were the bottom three. The population of the bottom three barely totals 2 million while the population of the top three tops totals more than 2 billion. Package delivery is an every day occurrence in the US while many other countries do not have this luxury.
