When you are seeking USPS delivery to your new wall-mounted mailbox, there are regulations that must be followed and some considerations to make before installation day. If these regulations are not met, then the USPS employee may not be able to legally deliver your mail.

Thankfully, the regulations for wall-mounted mailboxes are simpler than those for other types. There are a few requirements you must meet to receive USPS delivery.

  • Ensure that if you are replacing your curbside mailbox with a wall-mounted one, that you let your postmaster know. You will need the postmater’s permission to change your mailbox type.
  • Make sure that your mailbox is large enough to hold at least one day’s worth of mail. This should include items like envelopes, magazines, postcards, and catalogs. There are no specific size requirements from the USPS, but check your local codes and regulations.
  • Install your mailbox only for items that are paid for with postage. These boxes cannot accept items such as newspapers.
  • Ensure that your mailbox is easy for your postal carrier to see. This usually means that your unit is placed near your front door, and not behind any obstructions such as shrubs and other decorations.
  • Ensure that the flap if working properly and allows delivery.
  • Make sure your mail carrier has safe, easy access to your mailbox. Aggressive dogs, children’s toys in the walkway, an icy walkway, and other obstructions must be avoided.

It’s also a good idea to make sure that your wall-mounted mailbox is between 41 and 45 inches from the ground surface or the surface of your porch or deck. Curbside mailboxes are required to be at this height for ease of delivery, and your delivery person will appreciate all you do to make their job easier despite this not being a requirement. If you have any questions about the proper place for your mailbox, contact your postmaster.
