How California Certified Nurse Aide license verification works

A Certified Nurse Aide in California is licensed by the CA Nurse Aide Registry. 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.
