APO / FPO Military Mail Explained

What is an APO address or an FPO address? APO stands for "Army Post Office," and is associated with Army or Air Force installations. FPO stands for "Fleet Post Office," and is associated with Navy installations and ships.

What does "APO" mean?
"APO" stands for "Army Post Office". It is normally followed by a number which serves as a code for a particular military unit or installation. APOs were often mobile, and moved with the units to which they were attached. Thus, a cover with an APO cancellation could have been mailed from any of several different locations, depending on the date. Other abbreviations that mean basically the same thing are MPO (Military Post Office) and BFPO (British Forces Post Office).

Military addresses must show the grade, full name with middle name or initial, and PSC number, unit number, or ship name. Replace the city name with "APO " or "FPO," and the state with "AA," "AE," or "AP," and use a special ZIP Code.

All APO / FPO shipments must be made by using the United States Post Office (USPS).

Please note that some items cannot be shipped by APO / FPO. If you have questions, please contact us before placing any order so we can answer your question.
