License Plate Code for
Montana Counties
County numbers were originally assigned based on most populous to least populous counties; sequence numbers were assigned about 1930 and have not changed since then.
A plan was proposed in the 1999 Montana Legislature Session to change things, but it was defeated. An interesting update appeared in The Billings Gazette on 02 may 2014, showing what the county-number designation would be if 2010 census data were used instead of the 1930 data.

This site shows the state map and the ID number that goes with each county... like a 7-1234 license plate means the car is from Flathead County, where Kalispell is the county seat.
