Source and coverage

StateLicense downloads the official no-fee OCILB bulk roster, selects only EL, HV, HY, PL, and RE, and clears mailing-state and county filters. Ohio issues these commercial trade licenses to individuals; records preserve distinct company-label associations. Blank or ESCROW company labels use the reported individual name with explicit scope context. The board describes escrow as inactive, while some roster entries report active statuses, so all associations for a conflicting credential have status=unknown and require official confirmation. Weekly Monday polling is an operational schedule, not a source publication promise.

Coverage limitations

• General/residential contractors, municipal registrations, and adverse-status history are excluded. Licenses belong to individuals. ESCROW/status conflicts make every association for that credential unconfirmed; a company label alone does not establish current authority. Missing results do not establish adverse status.
• The roster omits original issue date, bonding, workers’ compensation, and disclosure facts. Effective term dates are not original issue dates. An expired date does not silently override the reported status.
