About this page
This page provides FAQs about the My Number system. The system offers three main benefits: administrative efficiency, improved public services, and fair social security through accurate income data. The My Number Card functions as a government-issued photo ID and enables electronic tax filing. Private sector use is possible through embedded digital certificates and IC chip applications, not the My Number itself. The usage scope is defined by law, and a 2023 amendment promotes expansion beyond social security, taxation, and disaster response. Further expansion plans are outlined in the digital society implementation strategy.
