Comprehensive guide to Florida License plate weight and county codes 1938 - 1975

By D.F. "Buddy" Harris and other notable contributors.


Beginning in 1938 Florida assigned a number for each county based on population at the time. This is the first digit(s) on a plate from this era. Dade county was largest (Miami) it  so they were assigned the number one. The codes were abolished with the 1980 license plates. So if your license plate begins with a (1) you now know it came from Dade County. See Chart Below for all county designations. All images are in my collection unless noted otherwise.

Florida License plates have also had an alphabetic code that told the weight or use of the vehicle that was also abolished with the 1980 license plates. This weight or use code is found on the plate immediately following the county code. The chart below shows these codes. Some letters were stacked on top of each other with a line between them. Since I can't depict that stacking with this font, I will use a forward slash between them as a representation.
