For damaged or malfunctioning mailboxes, please reach out to your local post office. They can guide you on repairs or replacements.

Before installing a new mailbox or replacing an old one, it’s important to follow specific guidelines set by the U.S. Postal Service (USPS). Because mail delivery is a federal service, USPS rules govern mailbox size, placement, construction, and approval—whether you live in a single-family home, apartment, or new development.

While the City of Mount Vernon does not regulate mailbox installation, we’re happy to help point you to the right resources. 

We recommend:

• Contacting your local post office: They can provide specific guidance and answer any questions you may have. Always consult your local postmaster to confirm compliance.
