How Colorado Registered Nurse license verification works

A Registered Nurse in Colorado is licensed by the CO Board of Nursing. 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: status expires issued effective license_type license_method compact board_actions documents other_licenses data_as_of.

Board note: DORA license dataset data.colorado.gov/7s5z-vewr (daily; rowsUpdatedAt 2026-11-03) queried live over SODA, then the Division's PrintLicenseDetails.aspx?cred=&contact= page (states primary source verification) as live evidence; the print page sits behind a Human Verification CAPTCHA after bursts (falls back to the dataset row); interactive LicenseLookup.aspx is FormShield image-CAPTCHA gated; captured 2026-11-03; RN, PN, APN (subcategory NP/CNS/CRNA/CNM)

What a Registered Nurse license check returns

Field checkPasses when
license_numberEqual to the board's number, ignoring prefix and leading zeros
nameLast name or declared alias matches; first name exact or nickname
license_typeThe record is a Registered Nurse license, strictly (no near-miss types)
statusThe board shows an active status; probation is active with a flag
expiresExpiration is on or after today, where the board publishes it
disciplinary_actionsRecorded 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.

Nurse Licensure Compact and multistate Registered Nurse licenses

Registered Nurse licenses can carry a multistate privilege under the Nurse Licensure Compact. When the Colorado 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.
