The U.S. state of [Colorado](/source/Colorado) first required its residents to register their [motor vehicles](/source/Motor_vehicle) and display [license plates](/source/Vehicle_registration_plate) in 1913. As of 2024, plates are issued by the [Colorado Department of Revenue](/source/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](/source/American_Association_of_Motor_Vehicle_Administrators), the [Automobile Manufacturers Association](/source/Automobile_Manufacturers_Association) and the [National Safety Council](/source/National_Safety_Council) that standardized the size for license plates for vehicles (except those for [motorcycles](/source/Motorcycle)) 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.

With the addition of the letter O, the die for the digit '0' was changed for better differentiation.[2] 1982 – June 1992 ABC-123 July 1992 – December 1999 ABC1234 January 2000 – mid 2015 Embossed dark green on reflective graphic plate with white and grey mountains against dark green background none 123-ABC 001-AAA to 999-ZZZ (see right) Letter Q not used in serials until 999-ZZZ was issued. Afterwards, Q was added to each position, starting with AAQ-001 to ZZQ-999 and AQA-001 to ZQZ-999, and ending with QAA-001 to QZZ-999. mid 2015 – mid 2018 ABC-123 Unused 1982–92 serials Serials progressed from QAA-001 to QZZ-999, then AQA-001 to ZQZ-999, then AAQ-001 to ZZQ-999. Following this, the letter O was used in every position, with the same order of progression. Reissued 1982–92 serials RAA-001 to RDP-999 were issued alongside the Q serials. Subsequent reissues beginning with A, B, C and D followed the O serials.[3] mid 2018 – present ABC-D12 AAA-A00 to FIG-W76 (as of November 2, 2025)[3] Manufactured, but not issued, alphabetically. The most progressive numbers are often found on low-volume special plates, as they are typically issued after being manufactured rather than kept in stock.

## 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 plates

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.

### 2000 to present

The serials on non-passenger types are embossed unless noted.

## Renewal date tags

Colorado implemented a monthly staggered registration system in 1978, with separate stickers for the month and year of the expiration date (placed at the bottom left and bottom right of the plate respectively). As of 2024, month stickers are blue on white, while year stickers rotate through a four-color system introduced in 2002, as follows:

- **02**
- **06**
- **10**
- **14**
