Basic Pension Number and Basic Pension Number Notice

A Basic Pension Number is a number to manage pension coverage record of each insured person. In principle, each person is assigned one Basic Pension Number which is not changed. When a person enrolls in Japanese public pension system for the first time and the registration procedure is completed, Japan Pension Service sends the person a Basic Pension Number Notice to inform the person of his/her Basic Pension Number, registered name and date of birth.
After you receive the Basic Pension Number Notice, please keep it in a safe place. If you have lost your Basic Pension Number Notice, you can apply for a reissue at JPS branch office.
