Choosing the right Commercial Mailbox

We sell commercial mailboxes designed for a variety of applications, including schools, hospital facilities, nursing homes, hotels, residential developments, apartment complexes, and more. The Cluster Box Unit (CBU) "takes the cake" as our most popular commercial mailbox designed for centralized outdoor mail delivery for multiple tenants. Below you'll find a detailed overview of our top commercial mailbox categories:

Cluster Mailboxes (CBUs)

Auth Florence and Salsbury Industries, the two leading commercial brands in the U.S., make USPS approved CBUs in 8-Door, 12-Door, 13-Door, and 16-Door configurations and in four architectural colors (you can also purchase Salsbury CBUs in Green and White, in addition to the four traditional colors). All units include a matching pedestal for installation.

Vertical Mailboxes

Vertical Mailboxes are part of the USPS 4B specification. In layman's terms, this means that customers typically only purchase them to replace existing units. You can purchase the vertical as either a surface mounted (on the wall) or recessed mounted unit (in the wall). They come in 3-Door, 4-Door, 5-Door, 6-Door, and 7-Door configurations. Like CBUs, the two mailbox brands we carry in this category are Auth Florence and Salsbury. Both are quality mailbox brands, so the selection is usually a matter of price and preference. You can also purchase private delivery units (for in-house mail distribution) if you do not need the USPS to deliver.

4C Horizontal Mailboxes

The 4C Horizontal is the industry standard for recessed mounted centralized delivery. Unlike the CBU, the 4C unit is usually recessed in a wall, indoors or outdoors, or in a kiosk (typically outdoors). However, you can purchase the 4C with a surface mount collar or free-standing kiosk if you do not intend to install the units into a wall. These can be purchased with or without parcel lockers for package delivery, and can be selected for either USPS or private delivery. Available in a variety of door configurations and architectural colors, the 4C mailbox is an ideal solution for apartment complexes and commercial buildings.

4B Horizontal Mailboxes

The predecessor of the 4C unit, customers typically purchase 4B mailboxes to replace existing 4B applications. Prior to purchasing new 4Bs to replace older units, we recommend you contact your local post office for approval. Since the post office will need to approve the application before it's installed, this extra precaution can save time and money. Typically, 4Cs will need to replace 4Bs when the wall opening (for housing the recessed units) is modified. For new construction, customers should purchase 4C mailboxes or Cluster Box Units to meet US Postal specifications.

Specialty Units

Sometimes customers require more specialized mail delivery products. Our selection of specialty mailboxes includes Salsbury Courier Boxes, Letter Drops, Door and Wall Mail Slots, as well as a variety of centralized mail units for private use (universities, etc.). If you cannot find the mailbox you are looking for, or if you would like more information regarding one of these products, please give us a call at (866) 707-0008 or open up our chat window (bottom left of the site) to speak with one of our customer care reps.
