National insurance contributions (NIC) - How do I get a national insurance (NI) number?

National insurance is a tax on your earnings that goes into the National Insurance Fund which pays for various benefits. This guide covers some basic information about NIC.

How do I get a national insurance (NI) number?

If you are looking for work, starting work or setting up as a self-employed person, you will need a national insurance number. If you have the right to work in the UK, you will need to telephone 0800 141 2075 to arrange to get one. They may require you to attend an 'Evidence of identity' interview.

There is some useful information on how to apply for a national insurance number on the Gov.UK website

Once your application is successful, you will receive a letter confirming your NI number. Take good care of this as it is your reminder of your NI number and you will need to use it when you contact HM Revenue and Customs (HMRC) or the Department for Work and Pensions (DWP). As soon as you have your NI number, you should tell your employer.
