**Not all mailboxes are USPS Approved for all applications!
Some older style mailboxes, such as the 4B+ compliant 1400 Series 4B+ Horizontal mailboxes and Vertical mailboxes, are only USPS Approved for replacement purposes. For any mailbox project that will involve U.S. Postal Service mail delivery, it is important to consult with the local Postmaster prior to ordering to make sure that it will meet with their approval.

As of October 5, 2006, all new construction and renovation designs REQUIRE U.S. Postal Service STD-4C compliant mailbox systems.
If your existing commercial mailbox meets USPS specifications, you can have it approved by your local postmaster. We carry new USPS-approved STD-4C mailboxes for new buildings or businesses that are renovating. USPS-approved mailboxes from U.S. Mail Supply are available in a variety of styles.
Buying a new mailbox might seem easy, however, there are regulations enforced by the United States Postal Service regarding mailbox specifications. Many postal customers aren’t aware of these regulations, then become confused when their mailbox isn’t approved.
USPS Approved Mailbox STD-4C Specifications
The USPS has to regulate the types and styles of mailboxes allowed for residential and commercial use to prevent delays and accidents when delivering mail. US Mail Supply offers a wide variety of USPS-approved mailboxes for homes and businesses. Residential and commercial mailboxes must meet specific USPS requirements, including box size, location, mail slot dimensions (when applicable), and identification information.
Depending on where you live, some of these restrictions and rules may not apply. To find out exactly what is and isn’t approved for use by the USPS, contact your local post office for clarification or visit the official USPS homepage.
