Federal Shipping Laws & Carrier Policies

Shipping Firearms & Ammunition

Federal rules and carrier requirements for shipping firearms, firearm parts, ammunition, and NFA firearms through UPS, FedEx, and USPS.

Shipping Firearms and Ammunition

Nonlicensees, FFLs & Shipping Carriers

Nonlicensee: An individual shipping a firearm who does not hold an FFL.

FFL: A federally licensed manufacturer, importer, dealer, collector, or other licensed firearms business operating within its authorized activities.

Common or contract carrier: A shipping company such as UPS or FedEx.

Mailable: An item that USPS permits to be sent through the United States Postal Service. For firearms, the type of firearm, sender, recipient, unloaded condition, packaging, and applicable postal requirements determine whether the firearm is mailable.

Firearm Parts: Under federal law, barrels, stocks, braces, handguards, grips, triggers, springs, sights, optics, magazines, and muzzle brakes are not firearms by themselves. Firearms under federal law include regulated frames and receivers, silencers and regulated silencer components, and machine-gun conversion devices. Certain unfinished frames, receivers, and parts kits are also classified as firearms under federal law.

Unregistered: An NFA firearm that is not recorded in the National Firearms Registration and Transfer Record. Completing ATF Form 4473 does not register a firearm under the NFA.

Shipping Firearms Is Legal When All Requirements Are Met

Firearms, firearm parts, and ammunition may be shipped only when the transaction, packaging, destination, and shipping method comply with state and federal laws and the selected carrier's policies.

When To Use An FFL

A licensed dealer can assist with lawful shipping for interstate transfers, repairs, returns to manufacturers, gunsmith work, Cerakote, stippling, optics cuts, milling, machining, and similar services when:

  • The firearm is a handgun, frame, receiver, or an NFA firearm, which still includes silencers, short-barreled rifles (SBRs), short-barreled shotguns (SBSs), Any Other Weapons (AOWs), machine guns, or destructive devices.
  • Shipping to an out-of-state buyer's receiving FFL.
  • Shipping for gunsmith or armorer work, returning a firearm to its manufacturer for repair, or shipping to a business performing firearm customization.

Shipping Guidance

Shipping Firearms Under Federal Law

A nonlicensee may ship a firearm directly to an FFL in any state. Federal law does not require another FFL to ship it. Contact the receiving FFL for its shipping requirements.

A nonlicensee may ship a firearm to themselves in another state for lawful activities. Another lawful individual may hold the package but cannot open it. This includes moving to another state, subject to the destination state's laws, including firearm and magazine capacity restrictions.

Certain antique firearms are excluded from the Gun Control Act's firearm definition, including qualifying firearms manufactured in or before 1898 and qualifying replicas.

Parts that are not firearms under federal law may be shipped without an FFL when the shipment complies with applicable law and the carrier accepts the item.

State Shipping Restrictions

Federal law does not override state firearm, ammunition, magazine, or firearm-part shipping restrictions. Some states require dealer delivery, purchaser verification, or prohibit certain items. For example, California requires most sales or transfers of unattached firearm barrels to be completed through a licensed California firearm dealer. Check the destination state's laws before shipping.

Federal Restrictions

  • A nonlicensee cannot ship a firearm directly to an individual who resides in another state for an ordinary private transfer. The receiving FFL must complete the applicable transfer process before delivering the firearm to the buyer or transferee.
  • The firearm and transaction must comply with the destination state's laws.
  • Federal law requires notice to a common or contract carrier in specified firearm shipments and prohibits outside package markings identifying the contents as a firearm.

ATF — NFA Firearm Shipping

  • ATF's October 9, 2026 nationwide nonenforcement policy does not remove silencers, SBRs, SBSs, or AOWs from the NFA. ATF has currently chosen not to enforce specific NFA provisions involving interstate transportation of NFA firearms. Federal transfer restrictions, state laws, and carrier requirements still apply.
  • Interstate transportation of an SBR or SBS requires prior ATF authorization on Form 5320.20, including unregistered SBRs and SBSs. This can be completed by mailing a paper form or online through ATF eForms.
  • Machine guns and destructive devices remain subject to their applicable NFA interstate transportation requirements.

Shipping Carrier Policies

USPS — Firearms & Ammunition

Allowed USPS Shipments

Firearms — Nonlicensee

  • A nonlicensee may mail an unloaded, mailable rifle or shotgun directly to an FFL in any state. The receiving FFL must agree to accept the shipment. Use secure packaging and a service with tracking and signature capture.
  • A nonlicensee may mail an unloaded, mailable rifle or shotgun to themselves in another state for lawful activities. A person holding the package for the nonlicensee must not open the package.
  • Parts that are not firearms under federal law, including stocks, handguards, sights, grips, triggers, and certain barrels, may be mailed when permitted by the destination state's laws.
  • Certain nonfirearm air guns may be mailed when applicable postal, adult-signature, and state-law requirements are met.

Firearms — FFL Dealer

  • Unloaded, mailable handguns, rifles, and shotguns may be mailed between authorized FFL dealers, manufacturers, and importers under the applicable USPS requirements. An FFL may also receive a qualifying rifle or shotgun mailed directly by a nonlicensee.

Ammunition

  • Empty, unprimed cartridge cases and shotgun hulls may be mailable when compliant with USPS requirements.

USPS Restrictions & NFA Firearms

Ammunition cannot be mailed with a firearm.

  • Nonlicensees cannot mail handguns.
  • Firearms must be unloaded; USPS may request inspection or certification. Outer packaging cannot identify the contents as a firearm.
  • Loaded small-arms ammunition, primers, blank cartridges, and regulated propellant powders are nonmailable.
  • Regulated frames, receivers, silencers, regulated silencer components, and machine-gun conversion devices are firearms under federal law and are subject to applicable USPS firearm mailing restrictions.
  • ATF's October 9, 2026 nonenforcement policy does not change USPS restrictions. Concealable SBRs and SBSs remain nonmailable under postal rules. Mailing other NFA firearms depends on postal classification, sender, recipient, and federal authorization.
  • Interstate transportation of an SBR or SBS requires prior ATF authorization on Form 5320.20.
  • State restrictions also apply. California requires most unattached firearm barrel transfers to be completed through a California FFL; other states restrict particular firearms, parts, and magazines.
