Residential Mailbox Rules

If you are looking to buy a new mailbox or to do some work and upgrade your current mailbox, follow the rules and regulations set forth by the United States Postal Service to ensure that you still receive your mail.

Get approval from your local post office before moving your mailbox or mailbox support.

Your mailbox should have your name on it. Your name should be at least 1 inch high; however, you are not allowed to have advertising on your mailbox.

Mailbox Height

Your mailbox should be approximately 41 to 45 inches in height from the road surface. If you are not able to put your mailbox at this height, contact the local post office branch for approval.
