step 1: gather your tools and materials (it’s easier than you think)

Unlike a post-mounted mailbox, installing a wall mount mailbox doesn’t require digging holes or pouring concrete. most wall mount mailboxes are designed for simple installation and often come with the necessary mounting hardware included.

here’s what you’ll need:

  • materials:
    • your wall mount mailbox
    • mounting hardware (bracket, support beams, screws, or bolts)
    • house numbers or address decals (optional for personalization)
  • tools:
    • drill
    • drill bit (masonry or rock bit if installing into brick or concrete)
    • level
    • tape measure
    • pencil, chalk, or marker

Before starting, inspect all the pieces in your mailbox kit to make sure nothing is missing or damaged. having everything on hand will make the process smooth and stress-free.

step 2: check with your local United States Postal Service Postmaster before you begin

One of the most important - and often overlooked - steps is getting approval from your local postmaster before installing your wall mount mailbox.

Unlike post-mounted mailboxes, which follow national placement guidelines, wall-mounted mailboxes fall under local USPS rules. your postmaster will confirm:

  • if wall mount mailboxes are allowed in your area
  • the correct placement for your home or business
  • whether you need to provide usps with a key if your mailbox has a lock

Tip from US Post Company: always consult the US Postal Service first. installing without approval could result in delayed or refused mail delivery.

step 3: measure for the perfect height

Your wall mount mailbox should be easy for both you and your postal carrier to access. the usps typically recommends a height of 41 to 45 inches from the ground to the bottom of the mailbox.

when measuring, consider obstacles like:

  • porch stairs
  • decorative plants or landscaping
  • railings, statues, or outdoor furniture
  • window and door clearance

The goal is to choose a location that is both convenient and compliant, while also enhancing your home’s exterior design.

step 4: mark your wall for easy installation

  1. hold the mailbox against the wall.
  2. use a pencil or marker to mark the location of the mounting holes.
  3. double-check alignment with a level to ensure your mailbox won’t be crooked.

Taking a few extra minutes to get this step right will save you from having to redo holes later.

step 5: drill the mounting holes with confidence 

With your marks in place, it’s time to drill.

  • for wood or siding walls, use a standard drill bit.
  • for brick, stucco, or concrete, use a masonry bit.

Drill into each marked spot carefully, ensuring your holes are deep enough to securely hold the mounting screws or anchors.

step 6: secure the mounting hardware for long-lasting strength

Now that the holes are ready, attach the mounting hardware. depending on your mailbox model and wall surface, this may include:

  • brackets
  • anchors
  • support beams

Follow the manufacturer’s instructions for your specific mailbox model. tighten everything securely, but avoid overtightening which could crack siding or damage brick.

step 7: hang your wall mount mailbox (the fun part!)

  1. position the mailbox against the hardware.
  2. drive screws into the bracket holes.
  3. start by inserting screws lightly, then check alignment with a level before tightening fully. 

Your wall mount mailbox should sit flush against the wall without gaps. if it feels uneven, loosen slightly, adjust, and retighten.

step 8: add finishing touches to personalize your mailbox

Congratulations!  Your wall mount mailbox is officially installed! now it’s time to add finishing touches:

  • install house numbers or your street address on the mailbox for easy identification
  • consider weatherproofing accessories like a mailbox cover or sealant for extra durability
  • for a polished look, match your mailbox finish with other exterior hardware such as door handles, light fixtures, or house numbers

These small details not only boost curb appeal but also make it easier for your carrier to locate your home.
