How Ohio Certified Respiratory Therapist license verification works

A Certified Respiratory Therapist in Ohio is licensed by the OH Respiratory Care 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 name board license_type status sub_status sub_category board_action issued effective expires compact address endorsements specialties national_certifications.

Board note: OH-ELICENSE-DATA: DataOhio 'State of Ohio Licensure - Individual' daily CSV (dataset fd9f9671; the eLicense Ohio database behind elicense.ohio.gov, 2.41M rows, QUERY_RUN_DATE = extract day); resolved via the portal API (versions/latest → download-file signed URL), indexed in SQLite, freshness gate 3 days; STATUS/SUB_STATUS/EXPIRATION_DATE/BOARD_ACTION per licence (BOARD_ACTION Yes/Pending flagged, never auto-failed); no DOB (name-only >1 hit = ambiguous). The live elicense.ohio.gov search stays WAF-blocked from this network. Captured 2026-11-03. Ohio issues one Respiratory Care Professional licence (Medical Board, RCP.…); rrt and crt both map to it.
