USPS-approved Cluster Mailboxes for Sale

If you’re a property owner of multiple residences, you may want to consider mailbox compartments approved by the United States Postal Service (USPS). Cluster mailboxes streamline your residents’ mail delivery process. At Mailbox Depot USA, we offer a variety of USPS-approved cluster mailbox options to suit your property needs.

What Is a Cluster Mailbox?

A cluster box unit (CBU) is an individual grouping of parcel locker compartments for centralized mail delivery. CBU mailboxes, or pedestal mailboxes, typically contain 8, 12, 13, or 16 parcel lockers for individual residents to receive small mail items. Certain commercial mailboxes also feature a couple of larger package lockers so residents can receive a key to unlock packages rather than visiting the property office.


Your local post office can help you install and maintain the primary master lock for the parcel lockers.

How Does Ingoing and Outgoing Mail Work?

Each cluster mailbox features an outgoing mail slot and a maximum security system to keep residents safe from mail theft. Each resident will have a key to unlock their individual parcel locker to retrieve mail. If they receive a package, the mail carrier will leave an additional key inside their locker to open one of the larger parcel lockers.

How Big Are Cluster Mailboxes?

Most standard cluster box unit options come in a few sizes. The individual compartment options are as follows:

  • Standard: 3” x 12” x 15”
  • Large: 4.75” x 12” x 15”
  • Extra-large: 6.5” x 12” x 15”

How To Pick the Right Cluster Box Units

We want to help you select the best cluster mailbox for your property’s needs. Aside from considering the number of units and size you will need, we recommend the following:

Seek USPS Approvals

You must obtain a USPS-approved CBU mailbox if you want your residents to receive all their mail. The options on our website all feature USPS approvals. For larger properties, we recommend the 16-cluster mailbox, as it offers the best value for the size and features.

Consider a High-security Cluster Box Unit

Each of our cluster mailbox options features adequate security measures, though if you want even stronger theft protection, we recommend a high-security CBU mailbox. You can shop for options with theft-proof fasteners and master doors to reduce potential risks.

Pick Styles to Match Your Property

Finally, it’s time to consider which cluster mailbox will look best on your property. Typically, you’ll place the CBU mailbox in a central location for easy access, so you don’t want it to stand out like a sore thumb. We offer decorative cluster mailbox options for high-end communities, featuring more detailed pedestals and columns.
