About Individual Number Notification

The Individual Number Notification is a document that informs you of your 12-digit individual number (My Number).
The document will include your name, date of birth, and My Number (individual number).
The Individual Number Notification will be delivered by registered mail approximately 2 to 3 weeks after it is registered in the resident record.

Note: Due to legal revisions, notification cards have been abolished, so for those who obtain My Number after May 25, 2020 (such as those who lived overseas or those who were born after the same day), We notify you of your My Number by sending you an "Individual Number Notification".

It will not be sent to those who already have a My Number.

• The Individual Number Notification Form cannot be used as a "document certifying your My Number" or as an "identification card."
• Individual number notifications cannot be reissued.
• The My Number written on your Individual Number Notification is an important number that you will use for the rest of your life. Please store it carefully so as not to disclose it to others.

The Individual Number Notification cannot be used as a document to prove your My Number, so if you need a document to prove your My Number, please obtain one of the following:

1. My number card (individual number) card
For information on how to obtain one, please refer to the "About My Number Card (Individual Number Card)" page.

　Please note that the Individual Number Notification Form also includes instructions for applying for a My Number Card. You can also apply for a My Number Card using your smartphone, mail, or other methods using the QR code on your Individual Number Notification or the "Individual Number Card Issuance Application Form" enclosed with your Individual Number Notification.

2. “Copy of resident record” or “certificate of items listed in resident record” with My Number card listed on it
For information on how to obtain one, please refer to the "Certificate of Residence" page.
