Yes, all of our mailboxes that are subject to USPS approval are formally and officially approved. We go through every step of the arduous process to properly design, test and certify our products according to the stringent USPS Standard 7 requirements.
It is important to note that there are many mailbox manufacturers who simply stamp their mailboxes “US MAIL – Approved by the US Postmaster General,” but whose mailboxes are not actually approved. While this is both illegal and unethical, the USPS enforcement system is insufficient to ensure this activity does not take place.
When in doubt, contact your local USPS Postmaster and ask them to provide you with the latest list of approved receptacles. You can also find the official list, published once a year, through USPS’ postal bulletin.
