For more information, please see the page on receiving My Number Cards.

Those that meet all of the following requirements can be used as identification documents.

• Documents marked with "Name and Date of Birth" or "Name and Address"
• Documents that match the name of Address, the name of resident certificate and the name of Address.

In addition to identification documents with a face photo such as a driver's license, passport, employee ID card and student ID card, you can create one of the identity verification documents with a face photo by creating a municipal-designated form called a face photo certificate .
There are three types of photo certificates: "for minors and adult guardians", "for those who are in facilities", and "for those who are receiving home care". For downloading the style, please see the page on receiving My Number Card by proxy/agent.
