other East Coast ships use FPO AE. Ships homeported
on the West Coast (Pacific Fleet) are assigned an FPO
AP (Armed Forces Pacific) address.
APO/FPO ADDRESSES (OVERSEAS
Like ships ZIP Codes, overseas activities also are
assigned their own unique ZIP + 4 codes. The list of all
APO/FPO (overseas activities) and address formats
are provided in section 12 of Publication 65-A. The
foreign locality should not be used in the address
format so that mail will qualify to be sent at the
domestic rate of postage. A higher rate of postage is
charged if the foreign country is used in conjunction
with an APO/FPO overseas address. See Module A of
the DMM for special instructions on addressing
overseas military mail.
When a ship changes its gateway address for
certain reasons (overhaul, operational homeport
change, and so forth), both the FPO gateway and
primary first five digits may change to accommodate
the geographical move. However, the four-digit
add-on will never change until the ship is
decommissioned. A ship is authorized to change its
primary five-digit ZIP Code when it changes homeport
due to extensive overhaul for more than 12 months.
OTHER MOBILE UNITS
Mobile units other than ships (staffs, squadrons,
and so forth) are also assigned a ZIP + 4 code. Even
