USPS-approved Commercial Mailboxes

When you own a commercial property with multiple tenants or occupants receiving mail, you need a USPS-approved centralized system to handle your deliveries. Many commercial mailboxes exist for various indoor and outdoor mail delivery applications. At Mailbox Depot USPS, we offer a wide range of commercial mailboxes within USPS regulations, giving you plenty of options to choose from.

Commercial Mailboxes With USPS Approval

USPS delivery services require you to meet various criteria for a commercial mailbox. If you own large commercial properties, like hospitals, universities, hotels, residential developments, apartment complexes, etc., you may choose between the following approved mailbox unit options.

Cluster Commercial Mailbox Options

Cluster box units include 8-, 12-, 13-, and 16-locker configurations on a single pedestal. The cluster box unit comes in a few colors to match your property’s style. After mail carriers deliver mail, occupants may access parcel lockers from the property’s cluster mailboxes using a key to retrieve their items.

4C Horizontal Mailboxes

4C horizontal mailboxes are the most up-to-date commercial drop boxes. The USPS requires all new construction or major renovation projects to buy commercial mailboxes adhering to 4C guidelines.

You can use 4C horizontal mailboxes for USPS or private mail delivery, in indoor or outdoor applications, and with various mounting options. Typically, customers choose recessed mounting, though you may also purchase the parcel locker unit as a free-standing system. You can select 4C horizontal mailboxes in various colors for your local post office or private delivery needs.

4B Horizontal Mailboxes

4B horizontal mailboxes are the outdated commercial postal service standard. You may only install a 4B system if replacing an old unit. You may not add 4B mailboxes in new construction or major renovation projects.

We recommend receiving approval from your local post office before selecting a 4B unit.

Vertical Mailboxes

Vertical mailboxes are also 4B classifications, which means you can only use them for replacement purposes. The units feature three to seven side-by-side parcel lockers. You can surface-mount vertical mailboxes onto the wall or recess-mount them into it.

Installing USPS Commercial Mailboxes

Private delivery systems without USPS approvals require entire in-house mail teams. Large organizations, like universities, may choose private systems, though most commercial businesses prefer USPS.

If you choose a USPS commercial mailbox over a private delivery system, your installation process will be fairly simple. First, you can shop and pick the right unit for your needs, selecting a style and color that matches your property.

You may also add various mailbox accessories, like name plates, address tags, combination locks, and more. Your local carriers will install and maintain the system’s master lock.
