Integration of driver's license and My Number Card
In addition to people obtaining a new driver's license or renewing a driver's license, people with a valid driver's license can record their driver's license information on the My Number Card IC chip at the driver's license center and police stations (except Yokohama Suijo Police Station) if they wish.
The My Number Card on which the driver's license information has been recorded can be used as a “My Number Card/Driver's License”.

[License information] Validity period, license type, conditions, license number, face photo, etc.
*A valid My Number Card is required to integrate your driver's license with your My Number Card. (You cannot record your license information on a My Number Card that has expired or has a broken IC chip.)
*You cannot use your My Number Card as a My Number Card/Driver's License unless you do the procedures to record your license information on it at the driver's license center or a police station. When recording driver’s license information to your My Number Card, a dedicated driver's license recording area is created in the IC chip, and the driver's license information is recorded in the area.
Patterns of possession (how to carry a driver’s license)
Depending on your preference, you can choose to possess
- just your driver's license
- just your My Number Card/Driver's License
- both your driver's license and My Number Card/Driver's License
You can change the way you possess your license at any time, regardless of your license renewal period. (A handling fee is required.)
Benefits of owning a My Number Card/Driver's License
１ One-Stop Service for address change, etc.
If you change your information on your My Number Card such as name, date of birth, and address at the municipal office by completing the consent procedure for using the One-Stop Service for Address Change, etc., you don’t need to submit a notification of changes for your driver's license at the driver's license center, etc.
*Those who only possess My Number Card/Driver's License are eligible.
*You will need to submit a valid electronic signature certificate to the driver's license center or a police station and select the consent items (address, name, or date of birth) in advance.
2 Linkage between Mynaportal and My Number Card/Driver's License
You will be able to use the following license-related services on the Mynaportal: "Check your license information", "Change your registered domicile online", and "Take an online lecture".
*Only holders of My Number Card/Driver's License or holders of both driver’s license and My Number Card/Driver’s License are eligible. ("Change your registered domicile online" is for those who only own a My Number Card/Driver's License.)
*You must submit a valid electronic certificate for signature at the driver's license center or a police station.
*After submitting the electronic certificate for signature at the driver's license center or a police station, you can complete the procedure for Mynaportal linkage by completing the initial linkage procedure (submission of the electronic certificate for signature) on the Mynaportal by yourself.
*If you have not taken the above necessary measures, you will need to change your registered domicile or change your name, date of birth and address on your My Number Card at the municipal office, and then submit a notification of change of My Number Card/Driver's License at the driver's license center or a police station.
3 Taking an Online Lecture for Renewal
If you already own a My Number Card/Driver's License, you can take a lecture of renewal for safe drivers and general drivers online by watching videos on your smartphone or computer.
*There is an aptitude test for renewal, so you will need to take the renewal procedure at the driver's license center or a police station after taking the online lecture for renewal.

4 Expedited license renewal in a prefecture other than your domicile

Cautions
1 Obligation to carry and present your driver's license or My Number Card/Driver's License
You are required to carry either your driver's license or your My Number Card/Driver's License with you when you drive a vehicle.
If you present your My Number Card/Driver's License at the request of a police officer due to a traffic violation, etc., you are obligated to comply with the police officer's request to take necessary measures to confirm the specific license information recorded on your My Number Card/Driver's License (such as reading it with a device).
2 Change of My Number Card/Driver's License entry
You cannot change the entry on the My Number Card (name, date of birth, and address) at a driver's license center or a police station. You must go through the procedure to change it at your municipality.
*If you have both My Number Card/Driver’s License and a driver’s license, you cannot change the entry on your driver's license unless you change the entry on the My Number Card.
However, if you fall under either of the following 2 conditions, you can change the entry on your driver’s license by presenting a copy of your certificate of residence.
- It hasn’t been 90 days or more since you submitted the notification of moving-in to the municipality, and you have not submitted your My Number Card to the municipality where you moved in.
- When you submitted your My Number Card to the municipality where you moved in, there was no blank space in the postscript column of the My Number Card.

3 Change of registered domicile of a My Number Card/Driver's License holder
If you have not completed the required procedures (submission of an electronic certificate for signature and linkage with Mynaportal), you will need to submit a copy of your certificate of residence (showing your registered domicile) to the driver's license center or a police station and do the procedures to change your registered domicile data on your driver’s license.
