Commercial Mailboxes Approved For USPS Delivery

Learn More About Commercial Mailboxes

We carry a complete line of commercial mailboxes approved for USPS delivery. Commercial mailboxes are designed for USPS centralized mailbox delivery where the United States Postal Service will be delivering mail to multi-tenant applications. These commercial mailboxes are perfect for universities, colleges, apartments, nursing homes, building lobbies, hospitals, condo complexes, multi-family buildings, and more and are available with many color options to fit the décor!

Commercial mailboxes are not only more efficient for the USPS, but they are also more secure than individual mailboxes — since mail is less likely to be stolen when multiple tenants receive mail in the same area.

Cluster Box Units

The standard for outdoor commercial mailboxes includes Cluster Box Units or CBUs. These cluster mailboxes are designed for use in all weather conditions to ensure postal customers receive the industry’s best mail experience. The Cluster Box Unit will provide safe personal outdoor mail delivery for many years to come.

4Cs

The standard for indoor commercial mailboxes are 4C Horizontal Mailboxes or 4Cs. There are two versions of 4C-specification indoor horizontal mailboxes – a standard version meeting USPS specifications and a high-security version well-exceeding requirements for facilities with high-security requirements or for areas considered high risk for mail theft. 4Cs can be built in or on a wall as well as on a pedestal, free-standing cabinet, or outdoor enclosure. Per the USPS, the 4C Standard Mailbox is mandatory on all new construction and major renovation projects as of October 2006.

4B+s

If you’re looking for mailboxes for your renovation or retrofit mailbox project, the 4B+ Horizontal Mailboxes are a great low-cost option and are ready to ship. In addition, vertical mailboxes are ideal for smaller apartment buildings, offices, or condominiums, for replacement and/or retrofit installations.
