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.
Is StateLicense an official government website?
No. StateLicense is an independent lookup and API service that aggregates public licensing information from official authorities.
How current is StateLicense data?
Refresh schedules vary by source. Check the source and record timestamps on each result and the expected cadence on the methodology page. Confirm current status with the issuing authority for important decisions.
Can I verify contractors across multiple states?
Yes. The lookup supports the jurisdictions listed below. New York coverage is New York City only, and some other states cover specific license categories rather than every contractor.
Is there an API for contractor license verification?
Yes. The StateLicense API supports search and license-number verification across the same covered sources. See the API overview and documentation for request and response details.
