Types of Mailboxes and Mailbox Posts
In addition to standard roadside boxes, there are different mailboxes designs to consider:
- Lockable Mailboxes: A locking mailbox allows the postal carrier to deliver mail through a slot or door but requires a key to retrieve the mail. Some locking mailboxes include a clip to hold outgoing mail in an unsecured part of the mailbox, while others cannot hold outgoing mail.
- Mailboxes Sized to Receive Small Packages: Depending on the model, these mailboxes can receive letters, larger padded envelopes and some boxes. You can also find drop boxes designed to receive only parcels.
- Decorative Mailboxes: You can find mailboxes in colors such as red or green, and unique mailboxes with the look of rubbed bronze, pewter and more. At Lowe’s, we carry many types of decorative mailboxes including metal mailboxes and plastic mailboxes. The most popular colors include gray, white and black mailboxes.
- Wall-Mount Mailboxes or Mail Slots: A wall-mount mailbox mounts on to a home’s exterior wall while a mail slot mounts on to an exterior door. These alternatives to roadside mailboxes are allowed in some areas.
Check with your local postmaster to see what types of mailboxes are suitable for your area. Your neighborhood or homeowners association may also have guidelines and requirements for mailbox designs.
The steps below describe how to install a post-mounted mailbox using 4-inch-by-4-inch pressure-treated lumber. If you want a different look, there are a couple of mailbox post ideas that'll give your mailbox a more finished appearance. Mailboxes with decorative posts typically install either over a wood post or directly in the ground. You can also purchase a decorative mailbox post to pair with an existing mailbox — just make sure it can support the correct amount of weight.
If you plan to paint your mailbox to coordinate with your home or outdoor decor, make sure the model you’re considering is paintable. Some manufacturers don’t recommend painting.
Roadside Mailbox Replacement
Keep federal regulations in mind when placing your new mailbox. Whether you're replacing an existing mailbox or installing for the first time, make sure it will be easily accessible for your mail carrier. Here are the guidelines for placing a mailbox, directly from the USPS:
- Position your mailbox 41 to 45 inches from the road surface to the bottom of the mailbox or point of mail entry.
- Place your mailbox 6 to 8 inches back from the curb. If you do not have a raised curb, contact your local postmaster for guidance.
- Put your house or apartment number on the mailbox.
- If your mailbox is on a different street from your house or apartment, put your full street address on the box.
- If you are attaching the box to your house, make sure the postal carrier can reach it easily from your sidewalk, steps, or porch.
Before beginning any excavation, call 811 to check for underground utilities.
Mailbox Maintenance
Unless you have a wall-mount mailbox that’s covered by an overhang, your mailbox is likely exposed to the elements. Weather conditions, including rain, snow and sun, can take a toll on your mailbox. Inspecting yours at least twice a year can ensure that it’s working properly to protect your mail. You’ll also want to make sure that the house number on your mailbox is clearly visible.
- Make sure the mailbox is secure on its post.
- Tighten the hinges on the mailbox door.
- Look for signs of rust or wear and tear.
- Make sure the closing clasp is secure.
- Replace any missing or discolored house numbers.
