What to Look For in a Mailbox


Tampering with U.S. mail is actually a federal crime, but that won't stop anyone from opening your mailbox to retrieve not just your mail but your personal information, too. A mailbox with a key or locking system is your best protection again stolen letters or identity theft. Be sure to look for one with a locking system that will still allow the mail carrier to deliver your mail.


Mailboxes on posts are particularly prone to accidents. Cars and bicycles run into them, trees fall on them, and strong winds can blow them down. Consider this when you choose both the box itself and the support you plan to attach it to. Wrought iron is lovely and might work on a quiet residential street. If you live on a winding country road you probably want to use wood or stone. The support post should be anchored into the ground no matter what type you choose. A metal box will weather the elements better than plastic.

Convenience and Compliance

Most of us probably check our mail every day, so it's worth the effort to make it easy on ourselves. If you receive a lot of large letters or packages, make sure your mailbox can handle the volume. If your street has a lot of traffic you can avoid stepping into the roadway with a mailbox that opens from both ends.

Be sure to find out and stick to the recommendations and requirements issued by the USP. When purchasing a new mailbox, look for one that is labeled as USP approved.

  • How do you install a mailbox?

    Place your mailbox at the street end of your driveway or next to your front door. For street boxes, you will need to anchor a sturdy support post in the ground no more than 24" deep. The post should be tall enough for the bottom of the mailbox to sit between 41" and 45" in height above the street surface. Place the post 6" to 8" back from the curb or street. A wall mounted mailbox must by 30" above the floor level at the exterior of the house. The slot must be 1 1/2" high by 7" wide. Horizontal slots must be hinged and vertical slots must be placed opposite the front door hinges.

  • How high should a mailbox be?

    The bottom of a street mounted mailbox should sit between 41" and 45" above the street surface. A wall mounted mailbox should be place 30" above the floor outside the home. For example: If your home has a front porch, measure up from that surface.

  • How do you paint a mailbox

    First remove any moving parts such as a flag. Clean the surface thoroughly with a mild detergent. Dry completely before applying a coat of primer. Primer paint formulated specifically for outdoor aluminum or plastic objects is available and recommended. Once your primer coat is completely dry, apply an outdoor paint.
