National Insurance Numbers

What is a National Insurance Number?

A National Insurance Number is the number allocated to you for use in all of your dealings with HM Revenue and Customers and Department for Work and Pensions (DWP). Your National Insurance number is individual to you but is not proof of identity.

When should I apply for a National Insurance Number?

You do not have a legal right to a National Insurance Number, but there are circumstances when you are legally obliged to apply for one and register for National Insurance purposes.
You must apply for a National Insurance Number if you are starting work. This must be done through the local Department for Work and Pensions, Jobcentre Plus office.

Where should I apply for a National Insurance Number?

For applications and enquires you should in the first instance call 0345 600 0643.

They will conduct an initial telephone interview and you will need to provide the following information:

You will be required to attend a further interview at the Jobcentre Plus office. The date and time will be confirmed in writing. You must keep this appointment in order to obtain your National Insurance Number.

What is the interview for?

At the interview there is a process of checks they need to go through to confirm your identity and to make sure you have the right to work in compliance with the immigration regulations. Below is an example of the evidence/documents you will need to take with you for the interview:

What happens after the interview?

If your application is successful you will be given a letter to show your employer confirmation that you have applied for a National Insurance Number. Details of your National Insurance Number will be sent to you as soon as possible after the interview and your National Insurance Number Card will be issued at a later stage.
