I learned pretty quickly that Montana license plates have a “pecking order” based on the relative size of the counties – according to population data from decades ago, that is.
Fechter.com explains it (and has a handy map): 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 Legislature Session to change things, but it was defeated.
I absolutely love that Butte/Silver Bow has retained the coveted #1 spot, even though Butte’s days as the largest town in Montana are long gone. Butte “made” Montana in so many ways, and it earned that #1 plate.
And I love that Cascade County – home! – is #2, despite falling behind Yellowstone, Missoula, Flathead, and Gallatin counties in recent years, population-wise.
Here’s the list of license plates by county; you can read more at BPRLicensePlates.com.

UPDATE: longtime blogger ZenPanda has a Flickr collection of ALL 56 PLATES! Here’s a sample – check ‘em all out here!


I have a photo of 1 plate from every county in a set on my flickr photo stream! It took me over a year & 95% where photographed in the Great Falls area.
WOOHOO! Kudos, ZenPanda! What was the most elusive plate?
39 (Fallon County) was the last one I found. I didn’t even see it on visits to Billings for over 9 months!
