This will be a periodic feature. I’ll be keeping track of new letter combinations I see on Iowa license plates until we reach 999ZZZ and the system divides by zero. (This category will also apply to anything else plate-related.)
In the past week there’s been YIZ, YJA…and YMB? I assume that means that the YK’s and YL’s have been assigned far from Polk County, and not that entire sequences were skipped.
Note: Standard license plates with a first letter of D, I, O, Q, U, or V were never issued, as far as I have seen.
