My Number Card
The My Number Card (Japanese: マイナンバーカード, Hepburn: mai nanbā kādo), officially Individual Number Card (Japanese: 個人番号カード, Hepburn: kojin bangō kādo), is an identity document issued to citizens of Japan and foreign residents which contains a unique 12-digit Individual Number (Japanese: 個人番号, Hepburn: kojin bangō) that serves as a national identification number in Japan. Unlike similar-looking identity cards in Europe, the My Number Card can be issued to both Japanese citizens and foreign residents, and is not proof of nationality.
