What do I do if I lose my National Insurance number?

If you lose the letter with your NI number on it the quickest way to get hold of it is to log onto the HM Revenue and Customs (HMRC) website.

If you have used it to access your tax records use the ID and password you set-up and if this is the first time you will have to set-up an account to access your records.

The second way is to look through letters you have received from HMRC. You will find your NI number on these letters. And finally, if you have been working your NI number will be on your payslip from your employer.

If you have no documentation with your NI number, then call HMRC on 0300 200 3500. It will take them around 15 days to write to you with your NI number.
