How do Cluster Mailboxes work?

In general, all cluster mailboxes work the same way. The carrier has a master key that opens the back of the unit or all the compartments at once. After placing the mail in the proper compartment, the carrier locks the CBU up and individual box users access their particular box with a key.

Who is responsible for Cluster Mailboxes?

The Postal Service is responsible for providing every customer a compartment lock and three (3) keys to his or her postal-owned Cluster Box Unit (CBU).  No key deposits are required and customers may duplicate their keys at no expense to the Postal Service.  The Postal Service keeps no duplicate keys and if the customer loses all the keys, the Postal Service will have to install a new lock and issue a new set of keys at the customer's expense.

If the mailbox is for a house, condo, apartment or other physical residence, customers make arrangements to pick up the mailbox key(s) from the owner, manager or prior resident when they move in.  The builder or property owner is responsible for providing lock and key service for privately owned cluster mailboxes.
