How much postage is required for APO/FPO mail?
You only have to provide normal, domestic postage on mail going to an APO or FPO address. The United States Post Office delivers APO and FPO mail to a military port, located on the East Coast or West Coast of the United States (depending on where the member is stationed/deployed), and the military takes over from there, transporting the mail via military cargo aircraft to the overseas location/Navy ship.
