Slots for incoming mail must be at least 1.75 inches high by 10 inches wide.All Mail Boss curbside boxes are USPS approved. They must meet the same functional requirements as standard mailboxes and must be approved by the postmaster.

Locking mailboxes effectively prevent theft of incoming mail. Newspaper receptacles may be mounted on the same post as the mailbox, but they must not contact it directly or be supported by it.

Steel or aluminum pipes with a 2-inch diameter are also acceptable.
