Military mail looks like domestic mail and behaves like something in between. Getting it wrong is easy, and the people waiting on the other end are the ones who pay for the mistake.
Here is what actually applies.
The good news: domestic rates
An APO, FPO or DPO address is treated as a domestic destination for pricing. A letter to a service member overseas takes ordinary domestic postage — a standard Forever stamp for a one-ounce letter — not international rates.
That is the single most useful fact here, and it is the one most people get backwards. Do not put Global Forever stamps on APO mail; you are simply overpaying.
The catch: it is addressed differently
Military addresses do not use a foreign country. The format replaces city and state with the APO/FPO/DPO designation and a regional code:
- Recipient's full name, including rank where applicable
- Unit and box number
- APO, FPO or DPO, followed by AA, AE or AP, then the ZIP
Never write the host country on the envelope. Adding it pushes the piece into international handling, which is slower and priced differently — the opposite of what you want.
Customs forms for anything but a letter
Letters and postcards go as they are. Anything with contents — a package, a padded mailer, most large envelopes — needs a customs declaration, even though the rate is domestic.
Restrictions vary by destination and change with circumstances. Some items are prohibited outright at particular APO/FPO locations, and that list is worth checking before packing rather than after.

Timelines: plan generously
Mail to a military address travels the domestic network, then enters the military postal system, and the second leg is the unpredictable one. Transit depends on the destination and on operational circumstances nobody publishes a schedule for.
The practical rule is to allow considerably longer than a domestic equivalent, and to build in real margin for holidays. Deadlines for holiday delivery to APO/FPO addresses fall much earlier than domestic ones — often by weeks — and they are published in advance each year. Missing them is the most common disappointment in military mail.
Scams that target military families
This audience gets targeted specifically, and "deployment sale" discount postage is a recurring pattern.
Genuine stamps carry phosphor tagging that sorting equipment verifies on every piece; untagged stock is pulled rather than delayed. For mail already facing a long, uncertain journey, that is the worst possible failure point.
Legitimate secondary-market sourcing supports roughly 10–20% off. Anything deeper, especially wrapped in patriotic framing, deserves the opposite of trust. The USPS Office of Inspector General and the FTC publish current fraud patterns.
| Audit point | Verified source | "Discount" risk |
|---|---|---|
| Phosphor tagging | Correct spec | Weak or absent |
| Audit trail | Commercial invoice | None / social payment |
| Business address | Verifiable US commercial | Hidden |
If you send regularly
Families and organizations that mail to deployed members every month should buy postage ahead. Forever stamps hold their value against rate increases, and having stock on hand removes one errand from an already long list. Rate changes are published by the Postal Regulatory Commission, with figures in the USPS Notice 123 charts; the governing regulations sit in CFR Title 39.
Where to buy
The USPS official store, or a specialist such as Forever Stamp Center for quantity at a defensible discount. For a local drop, the USPS location finder.
The short version
Domestic rates, domestic stamps. Never write the host country. Customs form for anything that is not a plain letter. Allow far more time than you think, and watch the holiday cut-offs.
