Format, years and the law

Format
99999, for example 91678 (9 any digit)

The format above follows the issuing rules: a registration that fits it is one this series could have issued.

Years issued
Documented since 2026; the format is likely older than the first year documented. Still issued.
Vehicle class
Dealer: trade/garage plates bound to a business, not a vehicle. Issued for car, van, truck, bus, motorcycle, and trailer.
About this plate
Everything except the binding is secondary, and the suspected geographic encoding is the most interesting unverified claim in this file.
How long it is valid
issued ANNUALLY (secondary), unlike the permanent semi-trailer plate, so the dealer plate is the short-cycle end of Illinois issuance
