Find your National Insurance number

Your National Insurance number is made up of 2 letters, 6 numbers and a final letter, for example QQ 12 34 56 C.

Where to find it

  • on your payslip
  • on your P60
  • in your personal tax account
  • on letters about tax, pensions or benefits
If you have lost it, you can ask HMRC to confirm it. You must be able to prove your identity.

If you do not have one

You’ll need a National Insurance number before you can register for Self Assessment.
