How Washington Dental Hygienist license verification works
A Dental Hygienist in Washington is licensed by the WA Dental 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).

Dentist and Dental Hygienist Compact and multistate Dental Hygienist licenses
Dental Hygienist licenses can carry a multistate privilege under the Dentist and Dental Hygienist Compact. When the Washington record shows a multistate license, the result includes multistate: true and the privilege states. Privilege status is confirmed at the compact's own lookup, never inferred.
