How Mississippi Certified Respiratory Therapist license verification works

A Certified Respiratory Therapist in Mississippi is licensed by the MS 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: name license_number license_type status license_class probation disciplinary_status issued expires.

Board note: MS-MSDHPL: MSDH Professional Licensure 'Individual Search' (www.msdhpl.webapps.ms.gov, ASP.NET WebForms, no captcha; the host omits its GlobalSign intermediate so the connector ships it). Name box is a contains match; number box takes digits only (prefix = licence type: OT/OTA/RCP/S/A/D …); grid Name / number / Issued / Expiration / Status (Active, Closed, 'Active, Temporary') / Disciplinary Status, 50 a page with a Next Page postback; details page per row via its in-session PublicPrintLicenseDetails token (Profession, number, name, issue/expiration, Status, Type Regular, Probation). RCP is one class → rrt and crt both map to it. Live 2026-11-04.
