Messages: 10,314. FPO most definitely stands for Fleet Post Office, they mostly service Navy and Marine personnel, however there are times when FPO's service Air Force and Army. APO stands for Army or Air Force Post Office. The same is true as above, however they ocassionally service Navy and Marine personnel.
What is an APO/FPO/DPO address? The concept of getting mail overseas to and from military personnel stationed overseas dates back many years. In formalizing this activity, the U.S. Postal Service (USPS) and the Department of Defense (DoD) negotiated an agreement called Overseas Military Mail, which exists to this day.
