Contractor license lookup FAQ

How do I check if a contractor is licensed?

Choose a jurisdiction and enter a license number, or search by business name. Compare the returned identity, status, type, dates, and source with the contractor's details. Confirm important decisions with the issuing authority.

Can I search a contractor by company name?

Yes. Use the Business name tab to find possible records. Similar names can refer to different businesses, so verify the number and other identifying details.

Is contractor license information public?

The licensing authorities listed here publish records that StateLicense makes searchable. Available fields and disclosure rules vary by source.

How do I verify a California contractor?

Search a CSLB license number or business name, review the status and classification, then confirm the current record directly with the California Contractors State License Board.

What does an inactive contractor license mean?

It means the returned record is not marked active in the source data. The reason and legal effect depend on the authority and license type; inspect the official record before deciding whether work is allowed.
