About personal number letter of advice (my number notice card)

Last Updated April 11, 2024

About numbering, notice of my number (personal number)

On October 5, 2015, a person with a resident certificate in Japan was assigned a My Number (personal number). After October 5, 2015, My Number will be assigned if you submit a birth registration form or move in from abroad to create a resident certificate in Japan for the first time.
 
We notified my number by "my number notification card" from October 5, 2015, but the handling of new issuance, reissue, name and address change was finished on May 24, 2020. From May 25, 2020, your My Number will be notified by the "Personal Number Notice". (We will send it by mail about 3 weeks after completing procedures such as birth registration form.)
