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 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 via First-Class Mail, Priority Mail or Priority Mail Express, it will move from major airport gateways in the U.S. to overseas airport gateways on commercial U.S.-owned aircraft. From the overseas airport gateways, mail is then moved by various methods to the designated Post Office facilities for delivery to the individual service member.
  • The MPSA provides service to 110 countries.
  • There are 224 land-based Post Office facilities and 143 on ships.
  • There are 952 ZIP Codes for military mail around the world, with more than 1.2 million delivery points.
