Check a Wisconsin license against our roster
Enter a license number for an instant check against ProFix's verified Wisconsin roster — a head start, not a replacement for the board. Then confirm current status at the Dept. of Safety & Professional Services (DSPS), 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 Wisconsin 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 it up at the Dept. of Safety & Professional Services (DSPS)
Use the official Wisconsin authority directly — not a third-party aggregator — so you're reading the source of truth. Wisconsin requires a Dwelling Contractor certification (and a Dwelling Contractor Qualifier) to pull permits for 1–2 family homes, and licenses the electrical, plumbing, and HVAC trades statewide. Verify any credential on the DSPS license lookup.
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.
