The U.S. state of New Mexico first required its residents to register their motor vehicles and display license plates in 1912. , plates are issued by the New Mexico Taxation and Revenue Department through its Motor Vehicle Division. Only rear plates have been required since 1961.

New Mexico is the only state that specifies "USA" on its license plates, so as to avoid confusion with the country Mexico, which it borders to the southwest.
