Q: What are the most important APO shipping restrictions to know before sending packages to military addresses?
For more information, see our complete guide: how to ship a package.
A: Only USPS delivers to APO/FPO addresses, packages must weigh under 70 pounds, and prohibited items include all perishables, alcohol, batteries over 100Wh, and firearms. As of January 2026, you cannot address mail to “Any Service Member” — every package must be addressed to a specific person with their rank and unit.
APO shipping restrictions determine what you can send to military personnel stationed overseas through Army Post Office (APO), Fleet Post Office (FPO), and Diplomatic Post Office (DPO) addresses. These restrictions protect military operations, comply with international shipping laws, and ensure packages reach service members safely.
The military mail network serves over 800 US military bases across 70+ countries in 2025, processing millions of packages annually. Understanding these rules prevents delivery delays, package returns, and compliance issues that affect 30% of incorrectly addressed military shipments.

What Items Are Prohibited from APO/FPO Shipping in 2026?
The USPS maintains strict prohibited items lists for military addresses due to security concerns and international regulations. These restrictions have been updated significantly in 2025 with enhanced AI-powered parcel scanning at sorting centers that detects non-compliant packages faster than ever before.
Completely prohibited items include:
- All perishable foods and beverages
- Alcohol and alcohol-containing products (hand sanitizer, mouthwash, fragrances)
- Batteries over 100Wh, power banks, UPS battery backup systems, jump starters
- Aerosols and flammable substances
- Firearms, ammunition, and firearm accessories
- Vaping products, tobacco, and e-cigarettes
- Knives and sharp objects
- Fireworks and explosive materials
- E-bikes and motorized vehicles
- Lottery tickets and gambling materials
- Drug paraphernalia
- Obscene or political materials
Electronics restrictions: FRS radios and GPS units are prohibited in many regions. Lithium batteries under 100Wh require special packaging documentation and must be installed in devices.
Mini Q&A:
- Can I ship coffee or snacks? Non-perishable coffee beans and sealed snacks are allowed, but anything requiring refrigeration is prohibited.

FAQ: APO Shipping Restrictions
What are the most important APO shipping restrictions to know?
Only USPS delivers to APO/FPO addresses, packages must stay under 70 pounds, and prohibited items include perishables, alcohol, aerosols, firearms, and batteries over 100Wh. Every package must be addressed to a specific service member by name, rank, and unit.
APO, FPO, and DPO: What Each Designation Means
The three military and diplomatic address types are not interchangeable, and the restrictions shift with each. APO (Army Post Office) serves Army and Air Force installations, FPO (Fleet Post Office) serves Navy and Marine Corps units including ships at sea, and DPO (Diplomatic Post Office) serves State Department personnel at embassies. A shipment to a ship-based FPO can face tighter size and hazmat limits than one to a fixed APO base, because storage and handling aboard a vessel differ from a land installation. Always ship to the exact APO/FPO/DPO designation on the recipient’s address rather than assuming their physical country.
Customs Forms and Country-Specific Restrictions
Every APO/FPO/DPO parcel crosses an international boundary in practice and requires a customs declaration (PS Form 2976 or 2976-R depending on value and size), even though you pay domestic postage. Critically, the prohibited-items list is not uniform — USPS publishes country-specific restrictions keyed to the ZIP code region serving each installation, because host-nation law applies. Items freely mailable to one APO ZIP can be banned at another: pork products, alcohol, religious materials, and certain publications are restricted to specific regions. Check the destination ZIP’s individual listing before packing, not just the general APO rules.
Addressing APO/FPO Mail So It Does Not Bounce
APO/FPO addresses use a rigid format that automated sorting depends on: the unit and box number, then “APO” or “FPO” in place of the city, then AA, AE, or AP as the “state” (AA for the Americas, AE for Europe/Middle East/Africa, AP for the Pacific), then the ZIP. Never write the host country name anywhere on the parcel — doing so can divert it into the international mail stream and out of the military postal system, which is both slower and subject to foreign customs. The absence of a country line is a feature, not an omission.
Size, Weight, and Flat-Rate Limits for APO/FPO
APO/FPO parcels move under USPS rules, and the size and weight caps are the same domestic package limits — but there is a military-specific advantage worth knowing: USPS offers a discounted flat-rate box for APO/FPO/DPO destinations, and provides free shipping supplies and a small per-box price reduction for military mail. Oversized or overweight parcels that exceed package limits cannot go this route at all. Consolidating a care package into a single properly sized flat-rate box, rather than several loose parcels, is usually both cheaper and faster through the military postal system, which handles boxed, well-labeled mail more efficiently than odd-shaped items.
Transit Times and Tracking Limits to APO Addresses
Delivery to an APO/FPO address is measured to the military postal gateway, not to the service member’s hand — once mail reaches the overseas military postal system it moves on military logistics that USPS tracking cannot see into. That is why tracking often goes quiet after the parcel reaches the gateway city and why arrival dates are less predictable than domestic delivery. Ships at sea (FPO) and forward-deployed units add the most variability. Plan care packages and time-sensitive items with a generous buffer, and set expectations that the tracking will stop updating well before the parcel actually arrives.

Why APO/FPO Uses Domestic Postage but Foreign Rules
The confusing thing about APO/FPO shipping is that it is priced as domestic mail yet governed partly by the restrictions of the country where the base physically sits. You buy a domestic label to a stateside-style ZIP, but the parcel clears through the military postal system and lands somewhere overseas, so an item that ships freely within the US can still be barred because the host nation prohibits it. That is why two APO addresses can carry different rules for the same product — one base’s host country may restrict alcohol, tobacco, or certain electronics that another’s does not. Checking the specific APO/FPO ZIP’s restriction list, not just the general USPS prohibited-items list, is what prevents a return or a seizure.
Mailing Windows and the Holiday APO Deadlines
Military mail runs on its own calendar, and the recommended send-by dates for APO/FPO destinations fall weeks earlier than domestic ones, especially around the winter holidays. Space-available and economy parcel services to distant commands close first, followed by the faster military-postal tiers, so a gift that would arrive in days domestically needs a much longer runway to an APO address. Building in that buffer — and shipping to the earlier of the two published deadlines when a base spans multiple service tiers — is the difference between an on-time arrival and a parcel that clears the military postal hub after the occasion has passed.
Customs Form 2976 and What Goes on It
Nearly every APO/FPO parcel needs a customs declaration, and getting it right is what keeps the package moving. The declaration lists each item, its quantity, and its value, and it must describe contents specifically — “gift” or “clothing” alone invites a hold, while “two cotton t-shirts” clears cleanly. Because the form doubles as the parcel’s clearance document through the military postal system, an accurate, itemized declaration is not paperwork for its own sake; it is what lets an APO shipment pass inspection without being opened, delayed, or bounced back to the sender.
