Can I renew my digital certificate after the renewal deadline has expired?

The renewal procedure is possible even after the expiration date has passed. However, please note that after the renewal deadline (expiration date of the digital certificate) has passed, you will not be able to use it as a digital certificate.
Renewal of the digital certificate requires a reservation at some counters. Please make a reservation based on the reservation ID described in the "Expiration date notice" that arrives about 3 months before the expiration date. If you live in a ward that does not require a reservation, please come to the counter directly.

You can also apply at the My Number Card Special Center (reservation required) that has jurisdiction over your ward. About jurisdiction ward, please see page of my number card special center.
