What is my National Insurance number?

You have a National Insurance number (sometimes referred to as a NINO) to make sure your National Insurance contributions and tax are recorded against your name only.
It's made up of letters and numbers.  It stays with you for life and never changes.  It typically looks something like:  NX999999C

If you’re a UK resident, you’ll normally be sent a National Insurance number automatically, just before your 16th birthday.

You can find your National Insurance number:

  • on your payslip
  • on your P60
  • on letters sent to you about tax, pension or benefits
  • in the National Insurance section of your personal tax account

If you still can't find it, you can ask for it to be sent to you by post here: lost national insurance number

What if I’ve never had a National Insurance number?

You need a National Insurance number if you want to work or claim benefits in the UK.   
If you’re new to the UK and/or you don’t already have a National Insurance number you can apply for one here: apply for national insurance number

Once you've found your National Insurance number you can enter it on your untied Profile (HMRC details) so that it’s always there when you need it!  See below:
