In a proposed rule set to appear in the Federal Register Thursday, the USPS said it plans to revise its mailing standards to follow guidance from the DOJ’s Office of Legal Counsel. The opinion concluded that federal law barring the mailing of concealable firearms, including handguns, is unconstitutional when applied to weapons protected under the Second Amendment.

Currently, handguns are generally nonmailable except under limited circumstances. The new proposal would allow handguns to be shipped under similar conditions as rifles and shotguns, provided they are unloaded, properly packaged, and shipped in compliance with federal, state, and local laws.

Postal officials emphasized that the agency consulted federal attorneys to draft the updated standards and is deferring to the DOJ’s legal interpretation. Changes would amend Publication 52, which governs hazardous, restricted, and perishable mail.

Despite the expansion, several safeguards remain. Unlawful firearms, such as machine guns and certain modified weapons, would still be prohibited. Packages cannot bear markings indicating they contain firearms, and most shipments must include tracking and signature confirmation.

Federally licensed gun dealers would largely continue unrestricted mailing, while nonlicensed sellers would still face conditions for interstate shipments. Exceptions also apply for law enforcement and government personnel, who could mail restricted handguns under specific conditions, including required affidavits for official use.

The Postal Service will accept public comments on the proposed rule for 30 days after publication. Officials stressed that feedback should address clarity and usability of the rules, rather than the constitutional issues highlighted by the DOJ.

If implemented, the revisions could reshape nationwide firearms shipping, broadening access while maintaining oversight and safety measures.
