What is a CSLB license lookup?

A CSLB license lookup checks a contractor record maintained by the California Contractors State License Board. You can run an exact CSLB license check when you have a number or search by business name when you need to identify possible California contractor records.

Match the returned business identity, status, classification, and dates to the contractor and proposed work. StateLicense also shows source and refresh information so you can decide when to confirm the current record directly with CSLB.

How to check a California contractor license

  1. 1

    Enter the contractor’s license number

    Use the number shown on the proposal, contract, advertisement, or company website. If you do not have it, search by business name.

  2. 2

    Match the contractor’s identity

    Confirm that the business name and location in the result match the company you are considering.

  3. 3

    Review license status and classification

    An active license alone is not enough—the classification should cover the type of work being proposed.

  4. 4

    Check compliance details

    Review expiration, bond, workers’ compensation, and any disclosure indicators. Confirm material decisions on the official CSLB record.

What does a CSLB license status mean?

Status is a starting point, not a complete approval decision. Read active, expired, suspended, or revoked status together with the expiration date and classification. Our CSLB license status guide explains the common review steps.

Confirm important decisions with CSLB

StateLicense makes records easier to search and interpret, but it does not replace the licensing authority. Review the official CSLB license check and its disclosures before relying on a result.
