Mailbox FAQ's

The postal patron provides a mailbox of light sheet metal or plastic construction that conforms to the requirements of the U.S. Postal Service.

It is TxDOT policy to furnish and install mailbox supports for all rural postal patrons located on state maintained highways. This service is provided free of charge.

Many types of custom and commercially available mailboxes and mailbox supports are potentially hazardous if hit by a vehicle.

TxDOT will only install mailboxes that meet the required crash tested safety specifications.

Home address numbers in a minimum one inch tall font should be placed on the mailbox to assist post office and emergency response providers. However, other decorative items that are attached add weight and can become hazardous objects if the mailbox were to be struck by a vehicle. These items may not be attached to the mailbox or to its support.
