Yes! All of our post mount MailBoss mailboxes have been stamped and approved by the U.S. Postmaster General, as listed here.

In order to stamp “US Mail approved by the Postmaster General” on a mailbox, the manufacturer must demonstrate that their manufacturing process is sound, and that the product meets a certain level of quality and integrity when subjected to harsh environmental conditions. Overall, the USPS approval process ensures that all curbside mailboxes are reasonably safe and efficient for mail carriers to use.

No mailbox is 100% theft proof. However, we have spent hours trying to break into our locking mailboxes with little success. Most US Mail approved locking mailboxes on the market can be opened in a matter of seconds with a screwdriver, or even by hand.
