Individual Number System

What is the Individual Number (My Number) system?

The Individual Number (My Number) system was launched in January 2016. The system is used to efficiently manage information in the areas of social insurance, taxation, disaster relief, and to confirm that personal information held by multiple agencies belongs to the same person. It was established as a social infrastructure to improve administrative efficiency, increase convenience for citizens, and ensure a fair and just society.

Sony Bank requires customers to provide their Individual Number (My Number) for investment trust transactions (service only available in Japanese), FX margin trading (service only available in Japanese), and Incoming/Outgoing foreign currency remittances.

In addition, since the implementation of the Numbering of deposit account system, which links customer information on deposit accounts with the account holders' Individual Number (My Number), from January 2018, we are requesting that all customers who have a deposit account with us submit their Individual Number (My Number). We appreciate your cooperation in this matter.

In accordance with the "Act on the Registration of Deposit and Savings Accounts" and the "Act on the Management of Deposit and Savings Accounts", which had taken effect in April 2024, customers, based on their consent, will be able to link their Individual Number (My Number) and register Public Money Receiving Accounts, at multiple financial institutions.
