How this service works
Verify a professional or business license by name or number against state licensing agency rosters, read live on every request. Public licensing records compiled from state agency sources. Free to cite with attribution. Redistribution inside a paid product requires a license. NOT a consumer report. This data may NOT be used, in whole or in part, as a factor in establishing any individual's eligibility for employment, credit, insurance, housing or tenancy, or for any other purpose under 15 U.S.C. 1681b. It may not be used to build a list of individuals, to re-identify individuals, or for targeted marketing.
Output
Returns a JSON object with found status, match count, and an array of matching license records. Each match includes the licensee name, state, licensing authority, license type, license number, current status (e.g. Active), expiration date, and a boolean flag indicating whether the license is expired as of today.
Example use cases
Contractor license check before hiring
“I'm about to hire a roofing contractor named Mike Larson in California — can you check if his contractor license is currently active before I sign anything?”
Real estate agent verification for a deal
“We're closing a deal with a broker named Sandra Chu, license number 489201, supposedly licensed in Florida — can you confirm her license is still valid and hasn't expired?”
Healthcare provider credential check
“Before I refer a patient, I need to verify that Dr. James Ortega holds an active medical license in New York — can you look him up against the state licensing records?”
Technical details
Endpoint
GEThttps://license.ccbaydata.com/v1/verifyWhen to prefer
Use this endpoint when you need real-time, live verification of a professional or business license against official state agency rosters — particularly when accuracy matters for due diligence, compliance, or contract decisions. Prefer this over static databases or background-check services when you need a current active/expired status rather than a historical snapshot. It is especially suited for single-record lookups by name or license number rather than bulk data processing.
Side effects
- License not found — returns found: false with match_count: 0 if no matching record exists
- Ambiguous name match — multiple records returned when a common name is searched without a license number
- State not covered — some states may not be included in the roster data
- Stale lookup window — data is read live but underlying agency sources may lag real-time revocations by hours
- Missing required query parameter — returns an error if neither name nor license number is provided
