This page explains the security of the My Number Card. The government has established a safe usage environment from technical and operational perspectives. In case of loss or theft, users can immediately suspend the card's functions via a 24/7 hotline, and reissue it within one week as a standard. The card features anti-counterfeiting measures on its surface, and accessing IC chip information requires a PIN or facial authentication.

Information is managed in a decentralized manner, exchanged only when necessary, and the system has obtained international security standard certification.

This page explains the security measures of the My Number Card provided by the Digital Agency. In case of loss or theft, card functions can be suspended immediately by phone and reissued within one week. Security is ensured through anti-counterfeiting ink, 4-digit PINs, facial recognition, and automatic IC chip destruction. Viewing the My Number alone cannot expose personal information. The system uses distributed management where information is exchanged only when necessary, not centralized in one location. The IC chip contains only essential information, excluding medical and financial data. International standard security certification has been obtained.
