Steps
Open CSLB's 'Check a License or HIS Registration' tool at cslb.ca.gov/OnlineServices/CheckLicenseII/CheckLicense.aspx
Search by the contractor's up-to-8-digit license number, or by business name (try progressively shorter prefixes if no match), or by personnel last/first name
Confirm the license classification includes C-33 (Painting and Decorating Contractor) and that status is active/current
Review bond and workers' compensation insurance status and any complaint disclosure shown on the result page
Cross-check an unfamiliar workers' comp carrier name via CSLB's separate Insurance Company Search tool
Known gotchas
This is a stateful web form, not a JSON API — there is no documented REST endpoint, so automation must parse HTML results
Business-name search returns are capped at 50 results and personnel-name search at 100 — narrow the query if nothing matches
