How to Check a Contractor License

Updated November 6, 2026

How Do You Check a Contractor License?

Ask for the license number and exact business name, then search the state board’s website. Confirm the license is active, the name matches your contract, the class covers your job and any disciplinary history is acceptable. Where the state has no license, ask your city or county building department what applies.

Five Checks

  1. Number and name. Ask for both in writing. They must match the contract.
  2. Status. Look for active, not expired or suspended.
  3. Class and limits. Some states limit a license by trade or job size.
  4. Bond and insurance. Some states show these; if not, ask for certificates.
  5. Complaints. Many boards show discipline. Search the name online as well.

Where There Is No State License

In some states, general contractors are regulated by cities and counties, or not at all. Call the building department where the work will happen. See your state’s system.
