Locking mailboxes effectively prevent theft of incoming mail. They must meet the same functional requirements as standard mailboxes and must be approved by the postmaster.

  • Slots for incoming mail must be at least 1.75 inches high by 10 inches wide.
  • Protective flaps on locking mailboxes must be oriented inward so that mail carriers can place mail into the slot without additional effort.
  • Locking mailbox slots must be large enough to hold the resident’s normal daily volume of mail.
  • Slots must also be large enough to accommodate unfolded US Priority Envelopes.
  • Locks cannot be used on contemporary or traditional mailbox designs.
  • USPS carriers do not open locked mailboxes and do not accept mailbox keys.
