The new Washington plates for passenger cars are 3 letters followed by 4 numbers (XYZ-1234), replacing the older 3 number-3 letter plates (123-XYZ). My 04 Tahoe has those.
Pickup truck plates were 5 numbers-1 letter, which my 91 has on it as YOM (12345-Z), but now are 1 letter-5 numbers-1 letter (A12345B). Too many registered vehicles is my guess and they ran out. Older than 30 years, you can apply for YOM or classic plates.
Older classic WA truck plates had T followed by the county letter then numbers. C for Spokane county.
Montana older truck plates had the county number followed by T then numbers, and in the 70-80s, passenger cars were county number followed by P. I think since sometime in the early 2000s 3 letter-3 number plates could be on cars or trucks without the county number designation without paying vanity plate fees. We've got trucks with the 3 -3. And if the vehicle is older than 10 years, permanent licensing on trucks or cars.
