What is a National Insurance number?
If you were born in the UK, you should have automatically received your National Insurance number just before your 16th birthday. If you’ve moved to the UK from another country, you may have a National Insurance number printed on the back of your biometric residence permit. Otherwise, you need to apply for a National Insurance number.
Your National Insurance number is made up of two letters, six digits, and then a final letter, so it should look something like this: QQ 123456 C. You’ll need to keep your National Insurance number safe, only sharing it with your employer, ISA provider and pension provider.
Finding your National Insurance number
You can find your National Insurance number on your payslip, P60 or letters about tax, benefits or pensions. If you’re self-employed and you have a personal tax account, you can login to your account and see your National Insurance number there.
If you don’t have any of these documents and you’re struggling to find your National Insurance number, you can call HMRC’s National Insurance number helpline on 0300 200 3500. They won’t be able to give you your number over the phone, but if you answer some questions correctly they will be able to post it to you.
Alternatively, you can fill in form CA5403 and post it to the address given on the form. If you haven’t been able to answer the questions on the phone, you will need to use this method.
