Military Postal Service Agency


An extension of the U.S. Postal Service, the Military Postal Service Agency (MPSA) provides Department of Defense personnel, their family members and other authorized users with mail services around the world.

  • The Military Postal Service Agency (MSPA) is the managing authority over Military Postal Service (MPS) operations.
  • MPS customers receive virtually the same level of service as if they were at home in the United States. Differences are based on the country in which they are stationed and the type of military operation in which they are involved.
  • Until 1980, each military service and government agency managed its own mail program. In 1980, the MPSA was formed and the Department of Defense designated the Secretary of the Army as the single military mail manager.
  • Created to link all the partners together with a common goal, the MPS provides postal services to military personnel around the world.
  • Military mail moves within the United States via the Postal Service transportation network to major postal mail processing facilities.
  • If the mail is First-Class, Priority Mail or Priority Mail Express, it will move from the major airport gateway in the U.S. to an overseas airport gateway on commercial U.S.-owned aircraft to overseas locations. From the overseas airport gateways, mail is then moved by various methods to the designated Post Offices for delivery to the individual.
  • The Military Postal Service Agency provides service to 103 countries.
  • There are 205 land-based Post Offices and 143 on ships.
  • There are 14,103 ZIP Codes for military mail around the world, with more than 1.2 million delivery points.
