About personal number notification

An individual number notification is a notification of your 12-digit individual number (my number).
The document contains your name, date of birth, My Number (personal number), etc.
Your Individual Number Notice will be sent to you by simple registered mail within 2 to 3 weeks after being registered in your resident record.

Note: Due to the revision of the law, notification cards have been abolished, so those who acquire My Number after May 25, 2020 (those who have lived overseas or were born on or after the same day, etc.) We inform you of your My Number by sending you an “Individual Number Notification”.

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

• The individual number notification cannot be used as a "document certifying my number" or as an "identification card".
• Individual number notifications cannot be reissued.
• The Individual Number listed on your Individual Number Notice is an important number that you will use for the rest of your life. Please keep it carefully so as not to inform others without good reason.

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 (personal number) card
Please refer to the "My Number Card (Individual Number Card)" page for how to obtain it.

　Information on applying for a My Number Card is also included in the Individual Number Notice. You can also apply for a My Number Card using the QR code on the Individual Number Notification or the "Individual Number Card Issuance Application Form" enclosed with the Individual Number Notification using a smartphone or by mail.

2. "Copy of resident's card" or "certificate of registered items in resident's card" with My Number Card
