Use of the Individual Number Card
as a Health Insurance Certificate
The Individual Number Card can be used as a Health Insurance Certificate!
Purpose of Adopting a Social Security and Tax Number System
The Social Security and Tax Number System assigns an individual number to every person with a certificate of residence and uses personal information that exists across multiple government agencies to confirm data about an individual in order to efficiently manage data in social security, tax, and disaster recovery matters.
The Japanese government adopted this social security and tax number system with the aim of achieving a fair and just association, enhancing public convenience, and developing administrative efficiency.
