An indoor mailroom staple for decades, these horizontal mailboxes are approved by USPS if they are a direct one-to-one replacement for apartment communities where the U.S. Postal Service is delivering the mail.  Horizontal mailboxes may be used in any private delivery application such as university or for military mail distribution. 

All new construction or renovation projects require USPS Approved STD-4C mailboxes.
