Q9-7 Is it compulsory to assign a number to a deposit account?

A9-7

When opening a deposit account, the financial institution will confirm your intention to submit your My Number (Note), but the My Number will not be assigned to your deposit account without your notification.

(Note) This is a response based on the "Act on Management, etc. of Deposits and Savings Accounts Using Personal Identification Numbers Based on the Will of Depositors (Act No. 39 of 2021)" (abbreviation: Account Management Act). Even before the enforcement of the said Act, financial institutions have been requesting depositors to submit their My Number in accordance with the Act on General Rules for National Taxes.

Q9-8: If I register a benefit to receive a public fund receiving account, will the number be assigned to my bank account?

The public fund receiving account Act and the deposit account numbering system are different systems.
Therefore, even if a public fund receiving account is registered, the My Number will not be assigned to a deposit account without notification to the financial institutions. No number will be assigned to a deposit account without the consent of the Principal.
