Apply for a National Insurance Number
If you do not already have a National Insurance number, you only need to apply for one if you are planning to:
- claim benefits
- apply for a student loan
- pay Class 3 voluntary National Insurance contributions
Before you Apply
Check how to find a lost National Insurance number.
If you are a UK Resident Aged 19 or Under
You will normally be sent a National Insurance number automatically, in the 3 months before your 16th birthday, if both the following are true:
- you live in the UK
- a parent has filled in a Child Benefit claim form for you
If you are aged 16 to 19 and did not get one, call HM Revenue and Customs.
If You Are Moving to the UK
You may already have a National Insurance (NI) number which will be printed on the back of your biometric residence permit (BRP).
If you do not have one, you must apply for a National Insurance number if you plan to work, apply for a student loan or claim benefits. You can only apply once you’re in the UK.
If You Are Applying for Benefits or a Student Loan
You can apply for a National Insurance number as part of your application for benefits or a student loan.
You will not need to call the National Insurance number application line. But you might need to attend an interview at Jobcentre Plus (or a processing centre if you’re in Northern Ireland).

The letter will also tell you which documents to bring to prove your identity, such as:
- passport or identity card

At the interview, you will be asked about your circumstances and why you need a National Insurance number. You will also be told how long it’ll take to get your National Insurance number.

Working Without a National Insurance Number
You can start work before your National Insurance number arrives if you can prove you can work in the UK. You should tell your employer that you’ve applied for one, and give it to them when you have it.
