解説

問 16

Incorrectア
My Number is assigned based not on whether one holds Japanese nationality, but on whether one has a residence registration in Japan. It is also assigned to foreign residents such as medium- to long-term residents, whereas overseas residents who have no residence registration are not assigned one. Therefore “It is assigned only to those who hold Japanese nationality” is incorrect.
Incorrectイ
The scope of use of My Number is strictly limited by the My Number Act to the fields of social security, taxation, and disaster response, and use for other purposes is prohibited. A company cannot divert it for internal management as an employee number.
Incorrectウ
My Number is assigned by the municipality (the government), and one cannot apply for and obtain a number of one’s own choosing. The number cannot be chosen by oneself.
エ
正解 My Number (the Individual Number) is a 12-digit number assigned by the municipality to each person who has a residence registration there, and in principle the same number is used throughout one’s life. It can be changed only when a limited reason applies — such as when the number is recognized as being at risk of leakage and misuse — and only when the person applies and the request is approved; it cannot be freely changed at the person’s own convenience. Therefore “エ”, which states that “an assigned My Number cannot be freely changed,” is appropriate.

ここがポイント

My Number is assigned to everyone who has a residence registration, and in principle it never changes. It cannot be changed at the person’s own convenience; changes are permitted only for limited reasons such as leakage.
The scope of use of My Number is limited by the My Number Act to the three fields of social security, taxation, and disaster response, and use for other purposes (such as diverting it to an employee number) is prohibited.
