1959-1976

In 1959, the state of Colorado officially transitioned away from numerical county codes in favor of a new system that allowed for a greater volume of plates to be issued: letter codes. Jackson, retaining its place as county 59/63, was assigned ZJ as its code. Click here for a full list of Colorado's county codes and allotments.
