My Number Cards used as Health Insurance Certificates


Upon notification, Association members and dependents can use My Number Cards as Health Insurance Certificates (after registering to use them as such) and are issued Notices of Eligibility Information. Those who do not have My Number Cards as their Health Insurance Certificates are issued Health Insurance Eligibility Certificates.
My Number Cards used as Health Insurance Certificates, Notices of Eligibility Information, and Health Insurance Eligibility Certificates serve as proof of eligibility of Association members and their dependents and are required to receive examination and treatment for illness and injury at healthcare institutions providing insurance-covered medical services. Keep these documents in a safe place.
Promptly submit an application to your affiliated Mutual Aid Association branch if any changes occur in the information (e.g., address or the status of a dependent) already reported to the Association or if any of the above documents are lost or damaged.
