Naval Post Office Facilities

Navy Numbers

Navy numbers were disguised mailing addresses established by the US Navy in early 1942 for security purposes. Initially Navy numbers were assigned to individual naval facilities at each location. Later the Navy recalled or inactivated many of these numbers and all facilities at a location were directed to use the General Navy number assigned for that location.

U.S. NAVY Post Office Branch numbers

The U.S. Navy Post Office Branch numbers are identification numbers assigned to each U.S. Naval shore base or other unit. The numbers were assigned by the U.S. Civil Post Office in New York. The branch numbers were used for accounting purposes by the civil post office. The were called "Branch numbers" because each of the Naval post office facilities were a branch of the New York Post Office. The 11.000 block of numbers were reserved for post offices assigned to U.S. Coast Guard activities.
