Cluster Box Units (CBUs) are centralized mail delivery systems approved by the USPS for residential and commercial use. They feature multiple tenant compartments and parcel lockers in a single unit, allowing efficient mail delivery to multiple addresses at one location.

The United States Postal Service addressed the shape of mailbox compartments and the demand for more secure mail and parcel delivery with a new standard, USPS-STD-4C. This standard replaces the traditional 4B+ horizontal mailboxes with improved security features and larger compartment sizes.

The demand for improved mailbox security prompted the United States Postal Service to develop this standard. This standard requires manufacturers to strengthen and improve the master door (arrow lock door) and tenant doors to resist forced entry attempts.
