What Is a Wall-Mount Mailbox?

A wall-mount mailbox is a post box that attaches to your home’s exterior wall, typically near the front porch. These mailboxes are great for urban homes, modern builds, townhouses, and any residence where curbside delivery isn't practical or required. Unlike post-mount mailboxes by the street, wall-mount mailboxes are used in door-to-door delivery zones.

Are Wall-Mount Mailboxes Approved by the USPS?

Yes – wall-mount mailboxes are USPS-approved as long as they meet certain size and accessibility guidelines. According to the USPS Domestic Mail Manual, wall-mounted mailboxes must be easily accessible to the mail carrier and positioned near the front entrance.

The USPS does not require prior approval for wall-mount mailboxes like it does for curbside post-mount mailbox designs, but they do require that the modern mailbox:

• Is large enough to hold daily mail volume (including magazines and small packages)
• Has a secure flap or covering to protect mail contents from weather
• Can be accessed without any obstruction

Pro Tip: All Post & Porch modern wall-mount mailboxes exceed USPS standards and are designed for daily use in both standard and high-volume households. Large mailbox, who?

Where Should I Install a Wall-Mount Mailbox?

The USPS says to place your wall-mount mailbox within easy reach of the mail carrier, typically near the main entryway, at a height between 41 and 45 inches from the ground.

This placement makes delivery easy and keeps your mail ultra-secure and dry. The mailbox should also be clearly visible and not blocked by doors, planters, or decor. If you’re mounting your mailbox on siding or brick, use appropriate fasteners – like masonry screws or wall anchors – and weatherproof sealant around any holes to prevent moisture intrusion.

Are Wall-Mount Mailboxes Secure?

Wall-mount mailboxes can be secure – especially when you choose a locking mailbox.

Security depends on the construction quality and design of the locking mailbox. Cheap, lightweight post boxes are easy to pry open. That’s why Post & Porch offers heavy-gauge steel wall-mounted mailboxes with integrated locking features.

These wall-mount locking mailboxes help protect:

• Sensitive letters and packages
• Small parcels
• Checks, statements, and prescriptions
• Peace of mind

A locking mailbox is especially important if you travel often or receive valuable items.

What Size Wall-Mount Mailbox Do I Need?

Choose a wall-mount mailbox size based on your typical mail volume and delivery habits.

Here’s a quick guide on choosing the size of a wall-mount mailbox:

• Standard Mailbox Size: Great for daily letters, envelopes, and magazines

Do Wall-Mount Mailboxes Work in All Weather Conditions?

Wall-mount mailboxes will only maintain their look if they’re made from high-quality, weather-resistant materials. Low-end mailboxes often rust, fade, or leak in rain or snow.

To prevent this, choose a wall-mount mailbox that’s:

• Powder-coated for rust resistance
• Sealed to prevent water intrusion
• Made from 14-gauge steel or aluminum

Every Post & Porch wall-mounted mailbox is built to withstand drastic rain, extreme snow, high winds, and UV rays, keeping your mail dry and your curb appeal intact.

Can I Use a Wall-Mount Mailbox in a Rural Area?

Using a wall-mount mailbox in a rural area depends on your mail delivery type.

Most rural areas use curbside delivery, which requires a post-mount mailbox positioned at the road’s edge. Wall-mounted mailboxes are generally used in areas with door-to-door service.

If you're unsure about using a wall-mount mailbox in your rural area, contact your local postmaster to confirm what type of post box is approved for your specific address.
