v t

The U.S. state of Colorado first required its residents to register their motor vehicles and display license plates in 1913. As of 2021, plates are issued by the Colorado Department of Revenue through its Division of Motor Vehicles. Front and rear plates are required for most classes of vehicles, while only rear plates are required for motorcycles and trailers.

The basic design of Colorado's license plate, a range of mountains against a white or green background, has been in use since 1960 (except for 1973 and 1975–76). In 2000, a screened, more detailed version of the mountain range replaced the previous dark green version.

Passenger baseplates[]

1913 to 1974[]

In 1956, the United States, Canada, and Mexico came to an agreement with the American Association of Motor Vehicle Administrators, the Automobile Manufacturers Association and the National Safety Council that standardized the size for license plates for vehicles (except those for motorcycles) at 6 inches (15 cm) in height by 12 inches (30 cm) in width, with standardized mounting holes.^[1] The 1955 (dated 1956) issue was the first Colorado license plate that fully complied with these standards: the 1954 (dated 1955) issue was 6 inches in height by 12 inches in width, but had non-standard mounting holes.

County coding[]

Colorado introduced numeric county codes on its passenger and motorcycle license plates in 1932, with the order of the codes based on the populations of each of the state's 63 counties at the time. These codes were used through 1958 (except in Denver, which last used code 1 in 1955).

Two-letter codes replaced the numeric codes in 1959, with blocks assigned to each county in the same order. For each code, serials ran to 9999 on passenger plates, and to 999 on motorcycle plates. The move to multi-year plates in the mid-1970s resulted in several counties exhausting their blocks and being assigned new ones.

In 1982, three-letter codes were introduced on passenger plates. AAA through DZZ were assigned to Denver, and GAA through TZZ to the next five most populous counties (Jefferson, El Paso, Boulder, Arapahoe and Adams); blocks of codes in the 'E', 'F', 'U', 'V' and 'W' series were then assigned to the remaining counties in roughly alphabetical order. For each code, serials ran from 001 to 999. Again, several counties exhausted their blocks and were assigned new ones, with Douglas and Elbert borrowing blocks of 'D' series codes from Denver's assignment. From July 1992, serials for each code ran from 1000 to 9999, and the previously unused letters I and O were added. Motorcycle plates continued to use two-letter codes (some of which were reassigned to other counties), with revised formats featuring three and later four digits between the letters (e.g. A123A and A1234A in Denver).

The table below reflects the two- and three-letter codes that were actually issued on passenger plates, rather than what was assigned.

Non-passenger and optional types, 2000 to present[]

When the current passenger baseplate was introduced in 2000, the state also simplified its non-passenger and specialty plates, issuing them in the same serial format (originally 123-ABC) and with similar graphic elements.
