Safety of My Number Card

In the procedure using My Number, it is difficult to abuse because identification documents with a photo of your face are required.

• The scope of use of My Number and collection and storage are strictly restricted by law.
• Since it is not a system to centrally manage personal information, information will not be leaked in a potato style.

The My Number system is not a mechanism (unified management) that collects and manages your information in one place. In managing information, we have adopted a system called "distributed management" in which personal information previously managed by each organization is continuously managed by that organization, and the necessary information is exchanged only when necessary. We do not create a specific common database, so there is no leakage of information from such places.

Even if it is lost or stolen, a third party cannot impersonate because it has a photo. In addition, the My Number Card is specially processed, such as engraving characters with a laser and applying complex pattern, making it difficult to counterfeit the face of the card.

The IC chip on My Number Card does not contain highly privacy-friendly information such as tax, pension, medical examination results or medicine information.

The 4-digit password required for reading the IC chip will be locked if you make a mistake more than a certain number of times, and you will not be able to unlock unless you complete the procedure. In addition, if you try to read information illegally, the IC chip is automatically broken, ensuring high security.

If you lose your card, you can use the card temporarily by connecting to the "My Number Comprehensive Toll Free Number (0120-95-0178)" by telephone. Foreign languages are also supported (English, Chinese, Korean, Spanish, Portuguese).
