I. What is My Number?
The My Number system is part of a new social infrastructure development in Japan. It was created to improve administrative efficiency, enhance public convenience, and help create a fairer and more just society. A My Number Card (or Individual Number Card,) is issued to all those who reside (i.e., those who have a certificate of residence) in Japan.
Your My Number will be required for administrative procedures related to social security, taxation, and disaster response.
II. Notification Card
The Notification Card is a paper card that notifies its recipient of his/her individual My Numbers. It includes your name which is registered at city office, date of birth, gender and My Number (Individual number). However, it does not include your picture so it cannot be use as your ID.
NOTE: The Notification Card can only be used to confirm your My Number. For identity verification, you need to have your passport, driver’s license, etc., alongside your Notification Card.
