Expansion of the Deposit Account Numbering System

From April 1, 2025, the deposit account numbering system, which links the My Number to the deposit account of a financial institution, was expanded. As part of this, if you number the account at the counter of a financial institution, you can enjoy the advantage of being able to know the location of the numbered account at the time of inheritance or disaster.
Notification of My Number to financial institutions is optional. This notification will not be used as an opportunity to inform the national and local governments of the balance of deposits and savings. For details, please refer to Public relations materials.
