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.
At each APO, FPO, or DPO, there is an equivalent to a-real-honest-to-goodness-Post Office staffed by members of the respective branch of service. While the layout of each APO/FPO/DPO varies by location, suffice it to say they look and operate just like a real Post Office. In fact, they have to, since we are talking about U.S. Mail. Each APO/FPO/DPO address holder has a mail lock box in which their mail is slotted. Since parcels can't fit in these boxes, delivery or notification slips, just like real ones, are put in the boxes whenever a parcel arrives.
