What is my National Insurance Number

If you have lost or forgotten your NI number, you can find it on your P60, or any letters sent to you by HMRC relating to tax, pensions and benefits. PSC cannot provide your NI number as they are not the creators of this information.

If you still can’t find your NI number, you can: fill in and return a CA5403 form to HMRC which can be found on HMRC website:

https://www.gov.uk/government/publications/national-insurance-get-your-national-insurance-number-in-writing-ca5403

Or alternatively phone the National Insurance number helpline on 0300 200 3502.
