Required documents
When the person or a member of the same household visits the office
(1) My Number Card (verify the four-digit PIN you set when you received your card)
(2) Identification documents for visitors (driver's license, passport, etc.) Note: Not required if the visitor is in person.
important point
- When processing procedures for members of the same household, please bring the My Number cards of all household members and, once each member's 4-digit PIN can be verified, one household member can process all of the procedures at once ( please confirm the 4-digit PIN number with each member in advance ).
- If you are unable to enter your 4-digit PIN, you will need to reset your PIN. For more information, please see here .
- The electronic signature certificate installed on your My Number card will become invalid if your address or name changes. If you wish to have a new one issued, you will need to come to the office in person to complete the procedure.
- However, if the procedure is done on the same day as the moving-in/moving-out procedure, and if the necessary items are brought with them, a member of the same household may complete the procedure on your behalf. For detailed procedure instructions, please see "Issuing an electronic signature certificate for a member of the same household (simultaneous with moving-in/moving-out)" below.

- A staff member will open the envelope and enter the PIN number on your behalf to complete the procedure.
- If the PIN is incorrect, the procedure cannot be completed.
- If you wish to issue a digital certificate for signing, the procedure cannot be completed on the same day.
- If you are having an agent submit a change of address notification or relocation notification, you will need to prepare both a "Power of attorney for change of address notification (relocation notification)" and a "Power of attorney [for My Number card address/name change procedure/separate household]".
