All residential mailboxes can be installed as a do-it-yourself project so long as you understand the regulations that you must follow when installing. For wall-mounted mailboxes, it is only necessary to ensure the mailbox is in an easy-to-see, easy-to-access location such as near your front door. Using mounting hardware, the wall-mounted unit is simply drilled into the wall.

For curbside mailboxes, both single-unit and multi-unit, the process is a bit more involved. Once you have reviewed USPS regulations, checked with your postmaster, and checked with your community for any additional rules (if applicable) you may begin the installation process.

  • Step One. Digging A Hole In The Right Spot. The first thing you’ll need to do is find a location that’s between six and eight inches back from the road or the curb. A tape measure or ruler will assist you during this task. If you’re installing a multi-unit mailbox with more than one post, you’ll need to take additional measurements to ensure that each post meets the requirements. Once completed, dig the hole or holes needed and ensure that each one is between 12 and 24 inches deep.
  • Step Two. Double-Checking. Placing your mailbox post or posts into the holes you’ve dug is a good way to ensure they’re at the correct depth and at just the right distance from the curb or road. Measure the top of the post to make sure it’s going to be 41 to 45 inches from the ground because this is where your mailbox will go.
  • Step Three. Bury The Post or Postss. Using dirt or by pouring concrete, bury the posts at the appropriate depth. It’s a good idea to fill in the hole so the dirt or concrete is a few inches above the ground’s surface. This will help to keep your mailbox stable.
  • Step Four. Attach Your Mailbox To the Post. Follow the manufacturer’s instructions for attaching the mailbox to the top of the post, and any instructions for accessories. Ensure any poured concrete is dry before doing this. Add your address using stickers if needed, and ensure it’s on the front door or the flag side of your box.
