Every year, the United States Postal Service (USPS) designates the third week of May to promote mailbox maintenance through an initiative called “Mailbox Improvement Week.” This program aims to ensure safety, efficiency, and protection when receiving mail.
- According to SILive, this initiative highlights the wear and tear mailboxes endure throughout the year due to weather conditions and daily use.
- This approval ensures compliance with established size and construction standards.
- For wall-mounted mailboxes, which replace traditional roadside mailboxes, obtaining permission from the local mail carrier is essential.
- In this regard, the USPS recommends annual inspections to prevent issues.
Between May 18 and 24, mailbox owners are encouraged to inspect and, if necessary, make repairs or upgrades. According to the USPS, “A well-maintained mailbox helps ensure every package and piece of mail reaches its destination safely and efficiently.”
According to SILive, this initiative highlights the wear and tear mailboxes endure throughout the year due to weather conditions and daily use.
The campaign includes a list of suggested tasks, such as replacing loose hinges on mailbox doors, repainting to prevent rust, relocating shifted posts, or updating house numbers. These small actions not only improve the appearance of mailboxes but also enhance overall mail delivery efficiency.
Doug Tulino, acting deputy postmaster general, stated: “Customers’ mailboxes are the first point of contact for receiving birthday cards, letters, and important documents.”

The USPS also reminds mailbox owners that certain technical aspects of design, construction, and placement require special attention. According to postal regulations, a mailbox must have the Postmaster General’s (PMG) seal of approval.
This approval ensures compliance with established size and construction standards.
If someone chooses to build or purchase a custom mailbox, they must ensure it meets these requirements to avoid delivery issues. Additionally, blueprints and measurements can be requested from the USPS Engineering Department to build mailboxes that comply with these standards.
Among the recommendations for mailbox placement, SILive reports that it should be positioned at a height of 41 to 45 inches from the ground to its base or mail entry point. It should also be located 6 to 8 inches from the curb’s edge.
For homes without a raised curb, it is advised to contact the local mail carrier for guidance on where to place the mailbox. Additionally, the house number should be clearly legible; if the mailbox is not directly in front of the home, the full address must be displayed on it.
For wall-mounted mailboxes, which replace traditional roadside mailboxes, obtaining permission from the local mail carrier is essential.
According to the USPS, this applies because these mailboxes are not required to have the PMG seal. However, they must be large enough to handle the usual volume of mail, including letter-sized envelopes and catalogs.
The USPS specifies that, for ease of use, wall-mounted mailboxes should be located near the home’s main entrance. It also clarifies that only items with postage are allowed in these mailboxes; newspapers, for example, must be placed in separate receptacles.
Ongoing maintenance is also crucial. Mailboxes are constantly exposed to the elements, which can deteriorate their ability to protect mail.
In this regard, the USPS recommends annual inspections to prevent issues.
These inspections should include tightening loose hinges, removing rust, replacing worn parts, and updating house numbers if they are faded or missing.
Security is also a priority. In addition to physical maintenance, the USPS urges homeowners to collect their mail promptly and avoid leaving letters or packages unattended in the mailbox or at the door for extended periods. If someone observes an unauthorized person tampering with a mailbox, they are asked to report it immediately to local police.
Regarding mailbox supports, the Federal Highway Administration (FHWA) recommends using materials that are stable but can yield if struck by a vehicle, such as 4×4-inch wooden posts or standard 2-inch-diameter steel or aluminum pipes.
Avoiding hazardous materials like heavy metal pipes, concrete posts, or farm equipment ensures both durability and safety.
Finally, homes with door slots for mail delivery should consider established standards. The opening must measure at least 1.5 by 7 inches and be located at least 30 inches above the ground.
These slots can be supplemented with an interior flap to prevent visibility into the home from the outside. According to the USPS, these improvements not only enhance privacy but also provide an additional solution for secure mail delivery in residential or urban areas.
