My Number Card Explained: What It Is and How to Apply

The My Number Card is a government-issued identification card that contains an IC chip. While every resident in Japan is assigned a 12-digit "My Number" (Individual Number), the physical card is optional but highly recommended for those looking to simplify administrative tasks and digital interactions with the government.

What can you do with a My Number Card?

The card is much more than just a piece of ID. Because it contains a secure chip, it allows you to perform several tasks that a standard residence card or driver's license cannot:

• Digital Identity Verification: You can use the card to log into the Myna Portal (the government's online service portal) to check your tax records, pension information, and residency details.

• Health Insurance Integration: You can link your card to your health insurance, allowing you to use it at many hospitals and clinics in place of a traditional insurance card.

• Convenience Store Services: You can use the card to print official certificates, such as your Certificate of Residence (Juminhyo), at convenience store multi-function printers.

• E-Tax Filing: It simplifies the process of filing national income tax returns online.

How to apply for your card

If you have received a notification in the mail regarding your Individual Number, you are eligible to apply. There are three main ways to start the process:

• Online Application: This is a common method. You can use your smartphone to scan the QR code provided in your notification mail. You will need to upload a digital photo of yourself.

• By Mail: You can fill out the application form included in your notification packet and mail it back with a printed photograph.

• At your Municipal Office: You can visit your local city, ward, or town hall to apply in person.

Please note that after you apply, it typically takes one to two months for the card to be issued. You will receive a notification in the mail when your card is ready for collection at your local municipal office. Fees for the initial issuance are generally free, but if you lose your card and need a replacement, a fee may apply. Always check with your specific local government office for the most current fee schedules and processing times.

Good to know

• PINs: When you collect your card, you will be asked to set different PINs (including numeric and alphanumeric passwords) for different types of transactions.

• Security: Do not share your 12-digit Individual Number or your card PINs with anyone.

• Loss: If you lose your card, contact your local municipality or the police immediately to have the card's functions suspended.
