The United States Postal Service (USPS) has regulations that govern the mounting of curbside residential mailboxes. The USPS requires a standardized curbside mail receptacle. Every mailbox designed for delivery in a city, or rural route or highway is a designated authorized depository under the law.

Safety and Convenience

When mounting a curbside mailbox, you must position it in such a way that it could be served quickly without the mail carrier leaving the vehicle. A mailbox must be mounted on the right-hand side of the road in the carrier's direction of travel, where driving on the left side would expose the carrier to traffic hazards or would be in violation of traffic laws and regulations.

Installation of the Mailbox

The bottom of the box must be at a vertical height of 41-45 inches from the road surface. You must seek the approval of the USPS before changing the location of the mailbox. The mailbox must be set back 6 to 8 inches from the front face of the curb. It must also be placed to conform to any additional state laws.

Advertising

Advertising on the mailbox or the supporting post is not allowed. You are allowed to attach a receptacle for newspaper delivery next to a USPS mailbox. It should, however, not touch or use any part of the mailbox for support. It must not interfere with the mail carrier's access to the mailbox. The USPS does not regulate mailbox supports unless they pose danger to its staff. But it is advisable to position a box in such a way that it can bend or fall away if struck.
