Free tool · Sub Check

Check a sub's license in seconds.

Enter a California contractor license number. See status, classifications, workers' comp and bond on file with the CSLB, with the date of the records.

Public CSLB records only. We don't save which licenses you look up. See our privacy notice.

What Sub Check shows

  • License status as the CSLB records it, and the expiration date.
  • Classifications, so you can match the license to your scope.
  • Workers' comp on file: the carrier and end date, or an exemption.
  • Contractor's bond on file.

It doesn't show general liability (CSLB doesn't track it for most licensees) and it isn't a rating of anyone's work. For the full checklist, read how to check a California contractor license.
