How Washington Certified Respiratory Therapist license verification works

A Certified Respiratory Therapist in Washington is licensed by the WA 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: credential_number name credential_type status issued last_issued expires ce_due birth_year multistate.

Board note: WA-DOH: data.wa.gov dataset qxh8-f4bd (DOH: 'primary source for verification of credentials', extracted daily 2am); SODA API per lookup, freshness gate 3 days; enforcement column withheld since fall 2026; DOH Provider Credential Search itself is Salesforce + CAPTCHA (blocked).

What a Certified Respiratory Therapist license check returns

Field check	Passes when
`license_number`	Equal to the board's number, ignoring prefix and leading zeros
`name`	Last name or declared alias matches; first name exact or nickname
`license_type`	The record is a Certified Respiratory Therapist license, strictly (no near-miss types)
`status`	The board shows an active status; probation is active with a flag
`expires`	Expiration is on or after today, where the board publishes it
`disciplinary_actions`	Recorded and flagged with any order documents; never silently dropped

Verdicts: verified, discrepancy, not_found, unable_to_verify (with a reason), pending. See how verdicts are decided.
