My Number (Individual Number) Notification
The My Number is a twelve-digit number assigned to each person who has a residence record.
An individual number notification card that states an individual number (“My Number”) will be sent by simple registered mail [no forwarding] to all residents of Japan. This includes newly registered residents who have moved here from overseas or were born recently.
Please keep your individual number notification card in a safe place for your reference and security.
