The United States Postal Service regulated the height and distance from the road a mailbox sits; to meet federal regulations, the bottom edge of the mailbox must sit between 41 and 45 inches from the surface of road. The front door of the mailbox must be at least 6 inches but not more than 8 inches from the edge of the road or the top of the curb. The USPS does not regulate the size, distance or height of the rear door on a two-door mailbox.
