How Illinois Certified Respiratory Therapist license verification works

A Certified Respiratory Therapist in Illinois is licensed by the IL 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.
