Shipping Guns via USPS? FFL Rules Explained

Last updated 4 days ago. Our resources are updated regularly but please keep in mind that links, programs, policies, and contact information do change.

A handgun headed to a licensed gunsmith can be a lawful repair shipment without being an eligible parcel for the post office. The United States Postal Service (USPS) permits ordinary owners without a federal firearms license to mail eligible rifles and shotguns, but its published handgun rules require specific authorized senders and recipients.

On January 15, 2026, the Justice Department’s Office of Legal Counsel concluded that the department could not constitutionally enforce the handgun-mailing ban against protected firearms. USPS’s August 2026 rulebook nevertheless retains the handgun restrictions and their limited exceptions. A change in federal prosecutors’ position has not, by itself, supplied an ordinary owner’s missing mailing route.

The Postal Service has proposed giving lawful handguns the same mailing treatment as rifles and shotguns, while keeping federal transfer laws in place. Mailing a gun requires a lawful recipient and a postal route that permits both the firearm and its sender.

Start with the firearm, not the license

The August 2026 edition of USPS’s Publication 52, Hazardous, Restricted, and Perishable Mail still lists handguns and other concealable firearms as nonmailable except between specified authorized parties. A federal firearms license (FFL) is not a universal pass through that exception.

USPS categorizes pistols, revolvers and concealable firearms, including short-barreled rifles and shotguns, as handguns. For its rifle and shotgun category, a rifle’s barrel must be at least 16 inches long and a shotgun’s at least 18 inches, with either weapon at least 26 inches overall and not concealable on a person. A shoulder-fired weapon can therefore fall on the handgun side of the postal distinction.

Ordinary handgun parts are mailable, but that permission excludes handgun frames, receivers and components regulated under federal firearms law. Shipping a disassembled gun calls for checking the regulated component, not merely calling the parcel a box of parts.

For concealable air guns that fall outside the firearm definition, USPS requires Adult Signature service and compliance with state and local regulations. The delivery requirement follows the postal category, not just whether the object looks like a firearm.

Match the firearm to its recipient

USPS permits eligible unloaded rifles and shotguns subject to federal firearms regulations and state and local laws. The destination then determines the mailing conditions.

Only the rifle or shotgun owner may open the interstate self-addressed parcel. The temporary custodian is a place to receive the package, not a substitute buyer.

For an ordinary sale to an unlicensed resident of another state, the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) says the firearm generally must go to an FFL in the buyer’s home state, where the buyer completes ATF Form 4473 and a National Instant Criminal Background Check System (NICS) check. Addressing that sale to the buyer’s house does not make it a shipment to oneself. A same-state transfer also requires that the seller not know or have reasonable cause to believe the recipient is barred from possessing a firearm, and state laws may impose additional restrictions.

Federal regulations allow an eligible person to send a firearm to a licensed importer, manufacturer or dealer for a lawful purpose and allow that business to return the firearm, or a replacement of the same kind and type, to the original sender across state lines. That return exception answers a transfer-law question, not whether a particular handgun parcel qualifies for USPS. For a repair, settle both the outbound route and the return carrier before sending the firearm.

A business FFL and a collector FFL are different

USPS’s business-license definition covers firearm manufacturers, importers and dealers, including gunsmiths and pawnbrokers, while its collector category covers acquiring and holding curios or relics. Curios or relics have special collector interest beyond sporting or defensive use, and may qualify through age of at least 50 years excluding replicas, museum-curator certification, or substantial value from rarity or historical association. The business role matters because the handgun trade exception requires qualifying parties at both ends.

A qualifying business mailer must file signed PS Form 1508, Statement by Shipper of Firearms, with the postmaster, confirming its licensed status, the trade or repair purpose, and, to the best of its knowledge, the recipient’s qualifying business license. The form records eligibility rather than creating it. An owner without the required business license cannot turn an ordinary handgun shipment into an eligible one by filling out the business form.

A curio-and-relic handgun may be mailed between licensed collectors only if it also meets USPS’s antique-firearm definition. That definition includes qualifying black-powder muzzle loaders that cannot use fixed ammunition, subject to specified conversion and frame-or-receiver exclusions, and certain ignition-system firearms made on or before 1898 or qualifying replicas. Old, collectible and antique are not interchangeable tests for a postal exception. Check the exact definition before treating a collector’s license as sufficient.

USPS also provides official-duty handgun routes involving licensed businesses or authorized government agents, prescribed certification and listed official-duty recipients. Those narrow government routes are not permission for a public employee’s personal handgun shipment.

Prepare the parcel and choose the service

USPS may require a rifle or shotgun package to be opened, or written certification, to confirm that the firearm is unloaded and eligible for mailing. Resolve acceptance requirements before sealing the package for the last time. Mailable firearms must be properly and securely packaged under USPS’s general packaging requirements. No markings on the outside wrapper or container may reveal that a mailable parcel contains a firearm.

Small-arms ammunition regulated as a Class 1 explosive, associated primers and blank cartridges, and firearm propellant powder are prohibited in USPS mail. Putting prohibited ammunition in a separate parcel does not create a postal shipping option.

USPS’s general firearm rule requires tracking and signature capture unless the shipment is between licensed dealers, manufacturers or importers. For rifles and shotguns mailed between those licensed businesses, USPS recommends tracking and signature capture rather than requiring them under that exception. Choose the service for the actual route rather than assuming every firearm parcel follows the same delivery rule.

International mail adds destination-country restrictions to the domestic firearm rules and prohibits many categories, including ordinary nonautomatic and semiautomatic rifles, revolvers and pistols, with a narrow exception for qualifying firearms of .50 caliber or less made before 1898. A domestic permission should never be treated as permission to mail the same gun abroad.

Verify the recipient and the carrier

ATF’s FFL eZ Check verifies a business license using its first 3 and last 5 digits. The system does not validate Type 03 collector or Type 06 ammunition-manufacturer licenses, so an error for those types does not establish that the license is invalid. A license check helps establish the recipient’s status, but it does not approve the sender’s postal route.

FedEx’s posted firearm policy requires an FFL, account approval and a Firearms Shipping Compliance Agreement, and prohibits firearm shipping by customers who lack an FFL. A private carrier is therefore not an automatic walk-in alternative for an unlicensed handgun owner. Ask a licensed business about a carrier-approved shipment rather than assuming that federal permission obliges a delivery company to accept it.

United Parcel Service (UPS) accepts firearm products under an approved shipping agreement from licensed importers, manufacturers, dealers or collectors to authorized recipients. An approved UPS shipper may provide a label to a customer returning firearm products to that shipper or another UPS-agreed address. Customers may tender those packed, prelabeled parcels at UPS Customer Centers or The UPS Store, or schedule a UPS pickup, with the approved shipper responsible for compliance. For a repair, ask the receiving business whether its approved agreement provides that customer-return route. A business-supplied return label is a limited route under that business’s agreement, not permission to buy an unrestricted firearm label.

For an interstate or foreign firearm shipment by a common or contract carrier to someone other than a licensed importer, manufacturer, dealer or collector, federal law requires written notice of the contents to the carrier. The same law bars a carrier from requiring an exterior firearm label and requires written acknowledgment of receipt for an interstate or foreign firearm delivery. Notice to the carrier and a label visible to everyone handling the box are different requirements.

Postmasters cannot give legal opinions on firearm shipments and are directed to refer customers seeking further information to ATF. Postal acceptance alone is not a substitute for checking the applicable transfer laws. A mailer can appeal a postmaster’s decision in writing to the Pricing and Classification Service Center, then appeal that center’s initial ruling to the USPS headquarters director of Product Classification.

The statute, the enforcement opinion and the proposed change

The federal handgun-mailing statute, 18 U.S.C. Section 1715, still states a penalty of a fine, up to 2 years in prison, or both for knowingly mailing a firearm it declares nonmailable. But the Justice Department’s January 15, 2026 opinion says the department may not constitutionally enforce that section against protected firearms, including handguns, and that USPS should conform its regulations. The penalty text therefore cannot be presented as a blanket description of the department’s announced enforcement position.

The Office of Legal Counsel argues that the restriction conflicts with the nation’s historical tradition of firearm regulation and burdens protected arms. The office reasons that continued enforcement makes lawful owners use burdensome workarounds or forgo transporting, receiving and maintaining their firearms, chilling the exercise of constitutional rights. Its constitutional argument therefore concerns the practical exercise of a protected right, not just a preference for cheaper postage.

As of April 23, 2026, the public docket in Shreve v. U.S. Postal Service, in the U.S. District Court for the Western District of Pennsylvania, recorded competing requests for judgment and an additional plaintiffs’ reply brief. The court granted permission for that additional reply on the same day. Those filings ask for a decision, rather than establish that the court adopted either constitutional position.

On March 2, 2026, New York Attorney General Letitia James and the attorneys general of New Jersey and Delaware sought to intervene to defend the statute. James’s coalition argued that the law regulates a method of transferring firearms rather than the right to keep or bear them. The coalition pointed to postal restrictions that, until 1879, allowed papers or a limited list of mailable goods that excluded firearms.

The coalition also argued that USPS has no legal obligation to ensure packages obey state gun laws, and that removing the restriction would force states to build costly new investigative and tracking systems. The disagreement concerns both the constitutional boundary and who would bear the enforcement burden of a broader mailing route.

USPS’s proposal, Revised Mailing Standards for Firearms, set May 4, 2026 as the public-comment deadline. That comment deadline has passed. The proposal would expand handgun mailing while retaining the requirement that firearms be unloaded and that mailers obey nonpostal firearm laws, including the Gun Control Act. The published August rulebook, rather than the proposal alone, supplies the mailing routes described above.

Even a broader postal rule would change how the parcel travels, not erase the separate restrictions on who may receive the firearm. The practical next step is to establish the lawful recipient first, then arrange a shipping route the sender and carrier can actually use.
