Vehicle registration plates of Kansas

The U.S. state of Kansas first required its residents to register their vehicles and display license plates in 1913. Plates are currently issued by the Kansas Department of Revenue through its Division of Vehicles and only rear plates have been required since 1956.

1913 to 1975
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 in in height by 12 in in width, with standardized mounting holes. The 1955 (dated 1956) issue was the first Kansas license plate that complied with these standards.

1976 to present
* In some cases, owners of standard embossed plates are being given renewals for 2025, rather than having to replace their plates with the newest design. There has been no official word from KDOR as to why this is taking place.

Replacement plates
Most specialty Kansas license plates are available to be reissued with the same serial number at the owner's request if they become damaged or illegible over time. Since Kansas does not have a rolling replate system, this duty falls on the vehicle owner to make sure their plates are legible to law enforcement and other motorists at all times.

This process includes all Collegiate, Firefighter, EMS, Disabled, and most other specialty plates. However, they will not be reissued with an embossed serial or original designs, even if the plate holder has an older design, such as the first edition Agriculture plates. Instead, they will be issued with the most current design of the plate, and will be completely flat.

The only style of plates that are not eligible to be reissued with the same serial are the standard Ad Astra or Capitol bases. If the owner wishes to retain their standard serial number, they can request it on a personalized vanity plate.

County coding
Kansas has a system of county codes used for identification of the home county of a state resident or company on license plates and state tax forms.

The codes are two letters based on the first letter of and another letter in the name of the county. There is no true convention for the selection of the letters; for example, Bourbon County is the only county that begins with "BO," yet its code is "BB." In most cases, but not all, as noted above, the only county that begins with two particular letters gets those letters. Exceptions are Decatur, Dickinson, Hodgeman, Leavenworth, Logan, McPherson (MC is used for Mitchell), Norton (NO is used for Neosho), Pawnee, and Pottawatomie.

The two-letter code began appearing on Kansas license plates in 1951. From 1930 to 1950, the code was a number based on the order a county ranked in terms of population based on the 1920 United States Census. From 1951 until 1988, the two letters were stamped on the license plate on the far left side, one letter on top of the other. Since then, the letters are on a sticker applied to the upper-left corner of the plate.

There is also a place on the address form of Kansas tax forms to place the county code.

Yearly Registration Decals
- Regular Auto decals started issuance in 1976 for 1977 expirations of the redesigned 1976 standard license plate. Trucks and other non-highway vehicles using the green 1975 plates were issued 1976 decals upon expiration.

- The decal sizing was changed from square to rectangular in 1994/1995 to be able to fit a similarly sized month sticker above the registration decal.

- The sizing was again changed in some 2012/2013 and all 2014 registrations to a square "smart sticker" that now includes the month, plate number, and registration year on one decal. Smart stickers for 2012 registrations were only issued to new plates in OCT, NOV, & DEC, and 2013 smart sticker issuance began in mid-May. Since the expiration month is now printed directly on the registration, separate month stickers were phased out and newer plates removed the debossed sticker well that had previously been used for the decal.

* Denotes a redesigned standard plate with a natural expiration.

Educational Institution Plates
These plates share a common all-numeric serial format that started at 1 with K-State in 1997.
