U.S. Government

When New Mexico first began licensing motor vehicles in 1912 there were no exceptions for either state- or federally-owned vehicles. These were issued regular “civilian” license plates at no charge, but the agencies which owned the vehicles also had the option of providing their own plates. In 1931 the state introduced a purpose-made tag called the U.S. Official plate for use by federal vehicles. As time went by, more and more individual federal agencies began providing their own plates, prompting the federal government in 1942 to create a standardized red, white and blue “federal shield” plate. The agencies using these new plates were identified by the serial number’s alpha prefix. By far the most common of these in New Mexico were “A” for Department of Agriculture and “I” for Department of the Interior. For other federal government plates used in New Mexico, see Civilian Conservation Corps and Boat.
 

The U.S. Soil Erosion Service existed only from September 1933 to April 1935, at which time it was renamed
as the U.S. Soil Conservation Service.  This plate was found in the Estancia Valley of New Mexico near Willard,
an area renowned for dryland farming of pinto beans until the destructive drought years of the 1930s.

Modern U.S. Government Plates
seen in New Mexico



By statute, Federal vehicles are required to be conspicuously identified by displaying “For Official Use Only,” “U.S. Government,” and the name of the agency owning the vehicle. Current U.S. Government license plates are designed to comply with this requirement, obviating the need to display this information elsewhere on the vehicle. These license plates are issued in two sizes, as follows:
1. Regular sized plate for sedans, trucks, and most trailers
2. Smaller motorcycle size plate for motorcycles, ATVs, small
    trailers, and similar vehicles.

U.S. Government License Plates are issued as a 2-plate pair (an A plate and a B plate, each so designated in the lower left corner) for front and back of sedans and trucks, and as a single plate for trailers and motorcycles (the A-plate only). Cars and trucks must always display both the A and B plates, even if the state where used requires only a single plate. All of these plates bear an expiration date and expire in 8 Years 6 months from issue.

Since October 2014 all modern Government license plates are supplied by the U.S. General Services Administration (GSA) in the format described above. Vehicles acquired by the agencies themselves receive license plates with a unique identifying prefix, a table of which can be seen by clicking here. Agencies which choose to have the GSA supply the vehicles to them through the GSA Interagency Motor Pool receive GSA license plates with a prefix of G followed by two numeric digits identifying the type of vehicle.
