Note: The My Number Card has an electronic certificate on its IC chip. It is what lets you use the card online, for example to get certificates at convenience stores. The certificate expires separately from the card itself, and this page is about renewing the certificate.

2. When can I renew? The deadline and what to bring are the same in all 7 cities
The electronic certificate expires on the 5th birthday after issue, regardless of age, and you can renew from the day after the date 3 months before expiry. If the expiry is July 15, the renewal period runs from April 16 to July 15 (Fukuoka City, electronic certificate renewal (Japanese)). After expiry, it is no longer a renewal but a new issue, and until then some services, such as convenience-store certificates and parts of Mynaportal, are unavailable.
If you go yourself, your My Number Card and PIN are enough. The signature PIN is 6-16 letters and numbers; the user-authentication and resident-register PINs are 4 digits. If you have forgotten a PIN, bring one more ID such as a driver’s license, and you can reset it on the spot and then renew (Kumamoto City, My Number Card and certificate renewal (Japanese)).
To send a representative, you fill in and seal the “inquiry and reply form” enclosed with the expiry notice, and the representative brings photo ID. A representative alone can do this only at the regular city office counters. Fukuoka’s temporary issuance center and the post offices in Kumamoto, Kagoshima and Miyazaki accept only the card holder.
The card’s own expiry (the 10th birthday for a card made at age 18 or older) is separate from the certificate, and the card itself is reissued. You apply for card renewal by mail or online and collect it after the notice arrives (Oita City, My Number Card and certificate renewal (Japanese)). If your certificate and card expire on the same day, you go through the card renewal process instead of a certificate-only renewal (Kagoshima City, certificate issue and renewal (Japanese)).
3. Fukuoka City
In Fukuoka, the Citizens’ Section at your ward office or a branch office renews without a reservation on weekdays from 8:45 to 17:15. You can also renew at the “My Number Card Temporary Issuance Center” on the 3rd floor of ACROS Fukuoka in Tenjin, open 12:00-20:00 Wednesday to Friday and 9:30-17:30 on weekends. The center gives priority to reservations, and a representative alone cannot use it. Reserve at the reservation call center (092-722-0650).
On weekends, the certificate service corners in Tenjin (city hall 1st floor) and Hakata Station (basement, Hakata exit of the subway station) also accept renewals from 9:00 to 17:00. They are reservation only, and you must go yourself. If you live in Higashi Ward, the certificate service corner in Chihaya (Namiki Square, 1st floor) is open until 18:30 on weekdays; if you live in Hakata Ward, the certificate issue corner on the 2nd floor of Hakata Ward Office is open on weekends (both reservation only). All are closed on public holidays and on the Sunday after the 3rd Saturday of each month.
From September 2026, post offices in the city have also started renewals. The number will grow by 12 offices at a time, reaching 36 in March 2027. Post offices are reservation only, and you reserve at least 4 business days before the day you want (Fukuoka City, reserving My Number Card services at post offices (Japanese)).

Common questions
Can I still use a certificate after it has expired?
No, but after expiry you can have a new one issued at a counter. It is an “issue” rather than a “renewal”, and it is free.
Can my family renew my certificate in Fukuoka for me?
Yes, at a ward office or branch office, even through an optional representative. The inquiry and reply form and the representative’s ID are needed. The temporary issuance center, certificate service corners and post offices accept only the card holder.
Is there a city where I can renew on a Saturday without a reservation?
Yes. In Kagoshima, special venues at the main office and Taniyama branch open on the 4th Saturday and do not take reservations that day. The card centers in Fukuoka, Kumamoto and Kagoshima and the holiday openings in Nagasaki and Oita are by reservation or reservation priority.
