USPS

The United States Postal Service (USPS; also known as the Post Office, U.S. Mail, or Postal Service) is an independent agency of the executive branch of the United States federal government responsible for providing postal service in the United States, including its insular areas and associated states. It is one of the few government agencies explicitly authorized by the United States Constitution.


The USPS traces its roots to 1775 during the Second Continental Congress, when Benjamin Franklin was appointed the first postmaster general, he also served a similar position for the colonies of the Kingdom of Great Britain. The Post Office Department was created in 1792 with the passage of the Postal Service Act. It was elevated to a cabinet-level department in 1872, and was transformed by the Postal Reorganization Act of 1970 into the United States Postal Service as an independent agency. Since the early 1980s, many direct tax subsidies to the USPS (with the exception of subsidies for costs associated with disabled and overseas voters) have been reduced or eliminated.


The USPS, as of 2019, has 469,934 career employees and 136,174 non-career employees. The Postal Service is legally obligated to serve all Americans, regardless of geography, at uniform price and quality. The Post Office has exclusive access to letter boxes marked "U.S. Mail" and personal letterboxes in the United States, but has to compete against private package delivery services, such as United Parcel Service, FedEx, and Amazon.


The tracking numbers of USPS Express Mail are 13 characters long, begin with two letters, and end with "US".
