Check a Ohio license against our roster
Enter a license number for an instant check against ProFix's verified Ohio roster — a head start, not a replacement for the board. Then confirm current status at the Ohio Construction Industry Licensing Board (OCILB) via eLicense, which is always the system of record.
Exact license number is the safest path.
A name search can only return possible matches. Confirm the exact license number before trusting any candidate.
1. Get the license number + legal business name
Ask the contractor for their Ohio license or registration number and the exact legal name it's held under. A real contractor gives this without hesitation — it's on their truck, estimates, and contract.
2. Look up the trade license — and check locally for a GC
For a licensed trade, use the Ohio Construction Industry Licensing Board (OCILB) via eLicense directly. Ohio licenses five commercial trades statewide through OCILB — plumbing, HVAC, electrical, hydronics, and refrigeration. General and residential contracting is licensed locally by your city or county. For a general contractor, Ohio verification happens at your city or county building department.
3. Confirm the status is ACTIVE
Only an active (or current) status means they're licensed today. Expired, suspended, or revoked is a hard stop — and a contractor who let it lapse is telling you something.
4. Check the classification matches your job
Licenses are scoped to specific trades. Confirm the classification covers the work you're hiring for, and that the name on the license matches the name on your contract.
5. Check bond, insurance, and complaints where shown
Many boards also show bond amount, workers' compensation, and complaint or disciplinary history. A bond and active workers' comp protect you; an open complaint is worth a direct conversation before you sign.
