The Short Answer

No, federal law does not resolve neighbor mail disputes; the USPS has authority over delivery but cannot adjudicate private property or access disagreements.

What the Law Says

Federal law governs the operation and protection of the U.S. mail system—but it does not empower federal agencies to mediate private disputes over mailbox placement, shared driveways, or alleged mail interference between neighbors.

The U.S. Postal Service (USPS) is an independent agency established by the Postal Reorganization Act of 1970 (39 U.S.C. § 101 et seq.), granting it operational control over mail delivery—but not jurisdiction over land use or trespass issues between private parties.

Criminal statutes like 18 U.S.C. § 1701 prohibit obstructing or impeding the mail, but enforcement requires proof of willful, intentional interference—not mere disagreement over where a mailbox sits or who retrieves mail from a shared location.

Civil remedies for mailbox access or property encroachment fall exclusively under state law (e.g., trespass, nuisance, or easement claims); no federal statute creates a private right of action for neighbors to sue each other over routine delivery disagreements.
