Social security/tax number system (My number system)

The My Number system is a social infrastructure that streamlines administration, increases convenience for citizens, and realizes a fair and just society.
By assigning a personal number (My Number) to every person with a resident record, we can efficiently manage information in the fields of social security, taxes, and disaster prevention, and collect personal information that exists in multiple institutions. This information is used to confirm that the information belongs to the same person.

• From October 2015, each citizen will be notified of a 12-digit My Number (personal number).
• Your My Number will never change unless there is a risk that your number information may be leaked or used fraudulently.
• You may not use your My Number or provide it to anyone else for purposes other than those prescribed by law.

(1) Improved convenience for citizens It becomes easier to confirm that information that exists in multiple institutions belongs to the same person, which reduces the burden on applicants by reducing the number of attached documents in administrative procedures.
　
(2) Improved administrative efficiency In the fields of social security, taxes, disasters, etc., the work of checking and inputting information at national and local governments will be reduced, leading to more efficient administrative operations.
　
(3) Realization of a fair and just society By making it easier to understand each person's income and receipt status of administrative services, it will prevent unfair evasion of burdens and unfair receipt of benefits, and will help people who are truly in need. We can provide detailed support to you.
