The 'My Number' (individual number) system
The 'My Number' system
'My Number' is a personal identification number (12 digits) issued to all individuals who complete the formalities for residence registration in Japan. This number is mainly used in the fields of taxation, welfare services and disaster countermeasures.
Approximately one month after you enter Japan and complete the resident registration procedures, you will receive an "Individual Number Notice" and an "Individual Number Card Issuance Application Form" by registered mail* to your registered address.
*Registered mail: Mail that keeps a record of delivery. Therefore, the recipient's signature is required. If the recipient is not at home, an "Undeliverable Item Notice" will be left in the mailbox. There are three ways to receive the mail.
1. Go to the post office with the "Undeliverable Item Notice" and your residence card.
2. Call the English Call Center to request re-delivery
Tel 0570-046-111 (Service hours: from 9:00 to 21:00)
