How Do I...
Placing the Mailbox
Here are some helpful guidelines to follow when installing your mailbox:
If you are attaching the box to your house, make sure the postal carrier can reach it easily from your sidewalk, steps, or porch.
If your mailbox is on a different street from your house or apartment, put your full street address on the box.
Place your mailbox 6" to 8" back from the curb. If you do not have a raised curb, contact your local postmaster for guidance.
Position your mailbox 41" to 45" above ground level.
Put your house or apartment number on the mailbox.
Installing the 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.
