How many licensed trades Illinois holds on the registers ATI collects, which trades they work in, and where they are. Straight from the state board, updated every night.
Illinois carries 18,251 skilled-trades licenses on its state register as of October 6, 2026, 145.4 per 100,000 residents.
Illinois licenses some trades locally. Cities and counties, not the state, issue several of these licenses, and ATI counts a local license only where it collects that local register. For those trades the figures below are a floor, not the state total.
Counts are license records, not people: a holder with more than one license appears once per license, and a contractor license is a business, not a worker.
