Here are the license number prefixes for the counties in Montana...
My wife and I have always loved looking at people's Montana license plates and trying to figure out where they are registered and from. The numbers used to be assigned based upon population but that is no longer accurate. Granted, with so many new vanity and speciality plates is getting harder to do! But here is a list I found at the Montana Association of Counties website. Have fun!

And there you go!!
Here is a screen print of them for now, until I get the time to make a real document.
If I find the time, I will also do Idaho since they are a neighboring state. Not sure how many other neighboring states do the same thing.
