What are the USPS requirements for installation at my house?
Customers are required to contact the local Post Office before installing the mailboxto ensure it’s correct placement and height at the street. Generally, mailboxes are installed at the height of 41-45 inches from the road surface to the inside floor of the mailbox or point of mail entry (locked designs) and are set back 6-8 inches from the face of curb or road edge to the mailbox door.
