Find a lost National Insurance number

You can find your National Insurance number on your payslip, P60, or letters about tax, pensions and benefits. If you have a personal tax account you can also view it there and print a confirmation letter.

If you still can’t find it, you can either:

HM Revenue and Customs (HMRC) won’t tell you your National Insurance number over the phone. They’ll post it to you and it will arrive within 10 working days.

You don’t need a National Insurance plastic card. HMRC no longer sends these cards out.

If you’ve never had a National Insurance number

You can apply for a National Insurance number if you’ve never had one.
