If you lose or damage your Health Insurance Eligibility Certificate

Health insurance cards are no longer newly issued or reissued since December 2, 2024. Use your My Number Card as your Health Insurance Certificate.

In principle, Health Insurance Eligibility Certificates are not issued to those who have registered their Individual Number Cards for use as Myna health insurance cards.
If your Individual Number Card is lost or stolen, you will need to complete the procedures to disable the card instead of the procedures described below. Contact the Individual Number Call Center general toll-free number (0120-95-0178).
