USPS Approved 4C Mailboxes
STD-4C Horizontal mailboxes are USPS approved and commonly used in apartment complexes, commercial buildings, residential developments, condominiums and several other applications. When you set up your 4C mailbox, the local post office will install an “Arrow Lock.” This lock is used for the local post master to open the unit and deliver the mail. When the U.S. Postal Service delivers a package to the parcel locker, a parcel locker key is placed in the recipient’s mailbox. Once the recipient opens the parcel locker, the key is automatically retained in the lock until it is removed with the USPS control key.
