Call Jobcentre Plus to apply for a National Insurance number.

You must have the right to work or study in the UK to get a National Insurance number. Jobcentre Plus might ask you to go to an interview to confirm your identity.

If you’re moving to the UK you can only apply once you’re here.

If you already have a National Insurance number and lost it, you should fill in form CA5403 or contact the helpline.

National Insurance number interview

Jobcentre Plus may write to you and ask you to come to an interview where you’ll be asked about your circumstances and why you need a National Insurance number.

The letter will also tell you which documents to bring to prove your identity, eg:

  • passport/identity card
  • residence permit
  • birth/adoption certificate
  • marriage/civil partnership certificate
  • driving licence

You turned 16 and didn’t get a number

You should automatically get a National Insurance number just before your 16th birthday if you live in the UK.

Call the National Insurance numbers helpline if you didn’t get one and you’re under 20.

If you’re over 20, contact the Jobcentre Plus application line.
