Colorado's temporary license plate. Number 80089U was issued to a vehicle from the Division of Motor Vehicles, as is evident by the "01" designation in the lower left. Number 02965X was issued by Stevinson Toyota, of Denver, as is evident by the "15" designation in the lower left.
The blown-up picture in the lower left is from the upper left of the plate, and the blown-up picture in the lower right comes from the upper right of the plate.
Recently, Colorado dropped its requirement that all temporary license plates be placed in the lower left corner of the rear window, since many vehicles temporary plates are issued to have no rear window.
For years, Colorado issued 45-day temporary plates, however that was recently changed to 60 days.
