Commercial Mailboxes - Multi-Tenant & High-Security
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 mailbox designed for centralized outdoor mail delivery for multiple tenants. Below you'll find a detailed overview of our top commercial categories:
Cluster Mailboxes (a.k.a. CBUs or Pedestal Mailboxes)
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.
USPS Mailboxes or Private Delivery?
VS 
Here are the key differences between a USPS approved and a private delivery mailbox:
A USPS approved mailbox meets USPS regulations for height, width, installation location, ADA accessibility compliance, and compartment size. Luckily for you, we already designate the mailboxes that meet these criteria, so all you really need to know are:
- The number of tenants that will need access to the mailbox
- The type of installation: whether the units will be recessed into an existing wall, mounted to an existing wall via surface mounted enclosures, or free standing in a kiosk
A mailbox for private delivery doesn't have to meet any of the USPS regulations since it will be serviced by an in-house mail department. This is most common with universities, dorms, or organizations that distribute mail in-house. If you purchase a mailbox for private use, the appropriate lock will be installed and keys will be included with the unit.
School & University Mailboxes
Any mailbox in our commercial category can be used at a school or university. Whether you need a pedestal cluster box, a 4C horizontal, a 4B horizontal, or a vertical unit depends on the following criteria:
- Do you need to purchase mailboxes for a new building or a new development, and will the USPS deliver to these mailboxes? If the answer is yes, then you need either a cluster or a 4C horizontal mailbox.
- Do you need to replace existing 4B vertical or horizontal mailboxes serviced by the USPS? If the answer is yes, you can purchase either the 4B vertical or horizontal for replacement purposes. However, we strongly recommend that you contact your local post office prior to purchasing one of these units to ensure that the USPS will deliver.
- Does your school, college, or university have in-house mail personnel that require their own keys to access your mailboxes? If yes, then you can purchase any of the above mailboxes as Private Delivery models.
