How Connecticut Plumber license verification works
A Plumber in Connecticut is licensed by the CT Contractor Licensing Board. PrimaryCheck looks the license up live at the board's public verification system (board lookup) by license number, or by name when no number is supplied. The record the board publishes is captured as evidence, hashed, and rendered into a proof PDF.
Fields returned for this board: license_number license_type status status_reason issued effective expires city state zip record_refreshed_on.
Board note: Dataset ngch-56tr (DCP occupational licensing): HIC/NHC/MCO registrations as contractor_general, ELC electricians (contractor + journeyperson), PLM plumbers, HTG heating/cooling. Many contractor rows are businesses (type != INDIVIDUAL) — name check notes the record type.
