If you live in the country, a mail carrier probably delivers the mail to a mailbox located at the end of the driveway. To ensure that your carrier delivers the mail, there are some regulations the United State Postal Service enforces. If you do not follow the regulations, be prepared to trek to the post office for your mail and packages.


There are three regulatory sizes for a mailbox. The most common size is 18.5 inches long, 5 inches wide and 6 inches high. Another size is 19.5 inches long, 6 inches wide and 7 inches high. For businesses, the common size is 19.5 inches long, 8 inches wide and 11.5 inches high.


For easy access for the mail carrier, the height of the mailbox needs to be 3 1/2 to 4 feet above the road surface.


The mailbox needs to be on the right side of the road in the direction of the traffic. Place it 6 to 8 inches from the face of the curb.


The path to the mailbox needs to be clear from obstructions. If you live where it snows, remove the snow. If grass grows near the mailbox, mow the grass.

Custom Boxes

If you wish to make your own box, you must see the postmaster for approval. The homemade box must meet the dimensions specified by the USPS.
