In the Nebraska license plate system, Dakota County was represented by the prefix "70" (as it had the 70th-largest number of vehicles registered in the state when the license plate system was established in 1922). In August 2009, the Dakota County Board of Commissioners reversed a decision to abandon this system for alphanumeric plates upon introduction of new license plates in 2011. Douglas, Lancaster, and Sarpy Counties remain the only counties with alphanumeric plates in the state.
