You can find your National Insurance number on your payslip, P60 or tax return.

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.

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

You turned 16 and didn’t get a number

You should automatically get a National Insurance number just before your 16th birthday. If you didn’t get one and you’re under 20, phone the National Insurance numbers helpline.

If you’re over 20 you need to apply for a National Insurance number.
