If you’re wondering how creative you can be with your mailbox, the answer is… very! While you have a lot of latitude in the creation and beautification of your box, there are still several rules and regulations to be aware of. The United States Postal Service does not “own” every mailbox, but they do have a say in how homeowners construct and use them. If you’re tired of your boring old mailbox and want to give it a glow-up, consider the following tips before you flex your creative muscles.
Measurements Matters
In most cases, the minimum size for a mailbox is about 7 inches high, 13 inches wide, and 16 inches deep. Beyond that, you have a lot of freedom in determining the size of your mailbox. However, there are requirements for that mailbox’s placement. Whether it’s an individual mailbox or a cluster mailbox chosen by a landlord, all mailboxes must be in locations a carrier can easily access. Mailboxes must be 41 to 45 inches above the road or other surface and should be about six to eight inches away from the curb. Cluster mailboxes, however, must have their plans approved by the local post office. It’s worth noting that if the mailbox rests on a post, it should be strong enough to hold the box but able to collapse if a vehicle collides with it.
Flag Facts
Measurements are just one aspect of the United States Postal Services standards for mailboxes. Do not incorporate any elements or decorations that will interfere with the mailbox’s few basic functions. For example, that little flag on the side, known as the carrier signal flag, should be present on a standard curbside box. The carrier or resident must be able to raise and lower the flag, and the flag must remain on the right side of the box. Mailbox owners cannot remove the flag or glue it in place. Interestingly, while your mailbox can be any color, the flag must not be green, brown, white, yellow, or blue, and it must not match the box’s color. To be safe, go with a bright red or orange flag.
Controlled Creativity
So, how creative can you be with your mailbox? As mentioned, the sky is the limit with color, patterns, decals, metal finishes, and other decoration(s). Naturally, you’ll want your mailbox to stand out so that the carrier and passersby can see it by day or night. You also want to ensure it doesn’t blend in with the background. Emblems, medallions, and similar devices are acceptable, but these additions shouldn’t place unnecessary weight on the box, have sharp points, or offer an obstacle to the carrier.
Most of all, do not use your mailbox to advertise or announce anything. USPS regulations forbid the affixing of fliers, stickers, or other advertisements on your mailbox. Limit the information to your name and address, and you’ll be fine.
