NAGC Vaccination Verification Instructions and Registration


All attendees, presenters, exhibitors, staff, volunteers, and vendors attending NAGC21 at the Gaylord Rockies Resort & Convention Center, Aurora, Colorado, November 10-14, 2021, must provide proof of vaccination to register for the in-person event.

NAGC is using CrowdPass, a HIPAA-compliant service, to verify vaccinations. It should only take you a few minutes to complete this simple and secure registration and upload process. CrowdPass follows a thorough two-step verification process, and most verifications are completed within an hour or two, but please be patient if you do not receive your confirmation until the next day. CrowdPass will accept vaccination status’ approved by the World Health Organization (WHO) and the Centers for Disease Control (CDC). As part of the approval process, you must also accept and sign both the NAGC Attendee Liability Waiver and Assumption of Risk form and the CrowdPass waiver.
