Illinois personalized & vanity plates
What Illinois lets you spell on a plate, and how to check availability yourself.
Plate Gator can't check Illinois availability automatically
Illinois' Pick-A-Plate site is guarded by Akamai bot defense that refuses automated sessions, so this state must be checked by hand.
So the only way to know for sure is to ask Illinois directly — the preview above still works, but Plate Gator will not run a live check for Illinois.
Illinois plate format rules
- Length
- 1–7 characters.
- Allowed characters
- Letters A–Z, numbers 0–9, and spaces.
Illinois splits personalization into two products. 'Vanity' plates are 1 to 7 letters or 1 to 3 numbers, never mixed; 'personalized' plates mix letters and numbers and require a space between the letter group and the number group.
