What is National Insurance – who needs it?
A National Insurance number (NINO) is the number given to you by the UK government to keep track of your tax record and benefit entitlements. The Department of Work & Pensions (DWP) (England, Scotland, and Wales) and the Department for Social Development (DSD – for Northern Ireland) will issue you a National Insurance number (NINO) just before your 16th birthday if your parents made child benefit claims. If your parents or guardians have not claimed child benefits, you must apply for a National Insurance number – if you intend to work in the UK.
Benefits of having NINo
If you have your NINO, you can:
- Apply for a student loan.
- Work in the UK – you can only work in the UK for nine weeks without a National Insurance Number.
