California Contractor License Lookup & Verify (CSLB)

Look up and verify any California contractor from a single search — type a CSLB license number, a business name, or a person's name and get back the licensed business, status, trade classifications, contractor's bond, and workers' comp, straight from the official CSLB registry. A name search matches both business names AND personnel/owner names (so you find every license a person is listed on), unioned and deduped. Built for fast verification, compliance checks, and enriching a name or license number into a full record.

How to use

Set the input, run the actor, and collect results from the run's dataset (export to JSON/CSV/Excel, or pull via the Apify API). Example input:

{
  "query": "Ransome Company",
  "includeDetails": true,
  "maxResults": 25
}

See Inputs below for every available field.

Inputs

Field	Required	Type	Default	Description
query	yes	string	"22726"	A CSLB license number (digits only, e.g. '22726') OR a name. Numbers are looked up directly. A name is searched against BOTH the business-name index AND the personnel/owner-name index, and the results are unioned (deduped by license #). For a person, enter 'First Last' (e.g. 'Phil Ransome') or 'Last, First' with a comma.
includeDetails	no	boolean	true	When on (default), each match is enriched with its full license record — entity type, issue/expiry dates, classifications, contractor's bond, and workers' comp. Turn off for a faster, lighter result list (license #, name, city, status only).
maxResults	no	integer	50	Cap on the number of matches returned (and enriched) in a single run. This is a lookup, not a bulk export — defaults to 50.
proxyConfiguration	no	object	{"useApifyProxy": false}	Optional. CSLB is usually reachable directly; enable a proxy (e.g. residential) only if a run is blocked or served a CAPTCHA challenge.

Pricing (Pay Per Event)

You pay per result (dataset-item) — no charge for empty runs. Example: 100 verified license records at $0.004/result ≈ $0.40.

Illustrative — the final per-result price is set at publish time. Apify platform usage (compute) is billed separately per your plan.

Use cases

• License verification & compliance — confirm a contractor's status, classifications, bond, and workers' comp before hiring or onboarding.
• Find every license a person holds or is listed on (RMO/RME/owner) — by personnel/owner name, even under different business names.
• Enrich a license number or a name into a full, structured record for your CRM, marketplace, or vetting workflow.
• Due diligence for lenders, insurers, and platforms that need authoritative CSLB data on demand.

Limitations & updates

Covers California's CSLB public registry only (public record under Business & Professions Code §7000 et seq.). Results reflect the live registry and change as it updates. A name search unions the business-name and personnel/owner-name indexes; personnel matches return the licenses a person is currently associated with. Runs are bounded (default 50 results) — refine a broad name to narrow it.

Which actor to choose

Part of the California CSLB contractor suite — pick the one that fits your goal:

• California Contractor Directory by Trade & County (CSLB) — You want a bulk lead list — every licensed contractor of a given trade (classification) in a county, in one run.
• California Contractor License Lookup & Verify (CSLB) (this actor) — You want to verify or look up specific contractors — by license number, business name, or a person's name (owner/personnel).
