Domestic prices, even overseas
Per the guide, shipping to an APO, FPO or DPO is charged at domestic postage prices regardless of where in the world the unit is stationed. The military ZIP does the routing.

Shipping to an APO address, by the book
Mail for service members overseas moves through a system of its own, and it is a USPS system: APO, FPO and DPO addresses are military mail lanes that the private parcel carriers do not serve. We checked the rules against the USPS military shipping guide on 2026-07-27 and summarized them here without decoration.

One carrier by design
Military mail is postal territory end to end, so this page trades rate tables for accurate rules.
What the USPS military guide actually says
Everything in this list comes from the USPS military and diplomatic mail guide, checked 2026-07-27. Where the guide is specific, we kept its specifics.
Customs forms come standard
Most APO and FPO parcels need one. USPS points shippers to its online tools, which select the right form, or to PS Form 2976-R filled out before visiting a retail counter.
The address is a format, not a place
Use the member’s name, rank and unit, then the APO or FPO designation with the state code AA, AE or AP and the ZIP. City and country names stay off the parcel.
Named recipients only
The guide is explicit that mail addressed to Any Service Member is no longer accepted. Every parcel needs a specific person on the first line.
DPO parcels have a size cap
Diplomatic post office shipments are limited to 27 inches in length and 14 in width and height, per the guide. Check the destination type before packing long items.
Restrictions vary by ZIP
Individual military ZIPs carry their own content restrictions depending on the host country. USPS surfaces these per destination, and they change, so check close to the send date.
Where our calculator honestly fits
SMKlog’s checkout compares USPS, UPS and FedEx on standard domestic lanes, and an APO lane is by definition a USPS-only affair, so the comparison we exist for does not apply to the military leg. Where we do help: pricing the stateside errands around a deployment, sending gear to a family home before a move, a care package to a base address in the continental US with a street address, or the return trip when belongings come back to a civilian ZIP. Those are ordinary parcels, and they quote in under a minute.
APO and FPO shipping questions
Can UPS or FedEx ship to an APO address?
No, military mail lanes are served by USPS. APO, FPO and DPO parcels enter the postal system and are handed to the military mail network from there.
Do I pay international rates for an APO parcel?
No. Per the USPS military guide, checked 2026-07-27, domestic prices apply to APO, FPO and DPO destinations even when the unit is overseas.
Is a customs form required for APO shipments?
For most of them, yes. USPS online tools pick the correct form during label creation, or PS Form 2976-R can be completed before visiting a retail counter.
How should an APO address be written?
Name, rank and unit on the top lines, then APO or FPO with the state code AA, AE or AP and the military ZIP. Leave the country and city off, and always name a specific recipient.
