Why do I need NIN?

To be able to work in the UK and to access many services you will need to have a National Insurance Number (NIN0), which is essential as proof of your identity for the HM Revenue & Customs (the government department responsible for tax) and the Department
for Work and Pensions (the government department responsible for employment, pensions and welfare).

This number allows the government to track your Social Security and National Pension contributions. At the same time, you will need this number when voting in the UK local or national elections or applying for a grant or loan as a student for your studies.

As it is a requirement for many services, it is advisable to obtain this number, even if you are not planning to work in the UK. If you do not have the NIN when offered a job, your employer will apply an emergency tax surcharge. You get it back when you sort your NIN.

The process for obtaining the NIN can take a few weeks. These are the documents employers may ask you for during the application process:

passport or identity card
residence permit (if non-EU)
birth or adoption certificate
marriage or civil partnership certificate driving licence
