What is a National Insurance Number?
You will need a National Insurance Number if you are going to earn an income in the UK, or plan to receive state benefits (government-funded aid). The NIN is not related to the health system.
A National Insurance Number is composed of letters and numbers: AA123456C.
It is unique for each individual, and never changes.
National Insurance Numbers apply for adults and children above 16 years old. Children under 16 do not need National Insurance Numbers.
