Is tampering with a neighbor's mailbox a federal offense?

What the Law Says

Federal law treats mailboxes as protected instruments of the U.S. Postal Service, regardless of ownership or location.

Under 18 U.S.C. § 1705, it is illegal to 'willfully or maliciously injure, deface, destroy, or remove' any letter box or other receptacle intended or used for receipt or delivery of mail. This applies even to curbside mailboxes on private property.

The statute covers acts like breaking, painting over, blocking, or removing a neighbor’s mailbox — whether done out of anger, prank, or dispute. Intent matters: accidental damage is not criminal, but deliberate or reckless conduct is prosecutable.

Courts have consistently upheld that mailbox tampering violates federal jurisdiction because the Postal Service operates under Congress’s constitutional authority to establish post offices and post roads (U.S. Const., Art. I, § 8, cl. 7). Even local disputes don’t exempt offenders from federal prosecution.

Statutory Text
