Where to Place the Mailbox
Here are some helpful guidelines to follow when placing your mailbox:
- Position your mailbox 41″ to 45″ from the road surface to the bottom of the mailbox or point of mail entry.
- Place your mailbox 6″ to 8″ back from the curb. If you do not have a raised curb, contact your local postmaster for guidance.
- Put your house or apartment number on the mailbox.
- If your mailbox is on a different street from your house or apartment, put your full street address on the box.

Installing the Mailbox Post
The best mailbox supports are stable but bend or fall away if a car hits them. The Federal Highway Administration recommends:
- A 4″ x 4″ wooden support or a 2″-diameter standard steel or aluminum pipe.
- Avoid unyielding and potentially dangerous supports, like heavy metal pipes, concrete posts, and farm equipment (e.g., milk cans filled with concrete).
- Bury your post no more than 24″ deep.
Mailbox Installation from USPS
Mailboxes are a tolerated obstruction when placed in the right-of-way.
Mailbox installations can not pose an undue hazard to traffic.
