In cases where proof of health insurance coverage is required, an active member ID card or certificate of coverage can typically suffice as proof.

In cases where proof of health insurance coverage is required, an active member ID card can typically suffice as proof. In the event that a physical member ID card is not available (the carrier does not provide physical cards or the employee has not received the ID cards yet) a certificate of coverage can suffice as proof of insurance coverage.
A certificate of coverage is an official document from a carrier stating an employee is active in the group policy. If you want to obtain a certificate of coverage, you should reach out directly to your carrier.
