A National Insurance number is a unique reference number used to track an individual’s National Insurance contributions. This number is used to calculate entitlement to certain benefits and services, such as the State Pension and unemployment benefits. If you have lost or damaged your National Insurance card, or if you have never received one, you can apply for a new one online or by mail.
There are several reasons why you might need to apply for a new National Insurance card. Perhaps you have lost or damaged your existing card, or maybe you have changed your name or address. Whatever the reason, it is important to apply for a new card as soon as possible to avoid any potential problems.
