How do I get a National Insurance number?

Updated on 28 July 2016

If you want to work or claim benefits in the UK you must have a National Insurance number (NINO). On this page we explain what a NINO is, where to get one and what to do if you lose or forget it.

To obtain a NINO you must be 16 or over and resident in Great Britain or Northern Ireland.

You can look for and start work without a NINO but you must then apply immediately.

What is a National Insurance number?

Your National Insurance number (NINO) ensures that the Government properly records your National Insurance contributions and taxes you pay. It also acts as your reference number for the whole social security system, for example when you contact the Department for Work and Pensions (DWP) or HM Revenue & Customs (HMRC).

Your NINO is unique to you throughout your life but it is not a form of identity. You must never use someone else’s NINO. Every person has their own number and each member of your family aged 16 or over should have their own number.

A NINO is made up of 2 letters, 6 numbers and a final letter, for example AB 12 34 56 C.

Where do I get a National Insurance number from?

You usually get sent a National Insurance number (NINO) just before your 16th birthday.

In England, Scotland and Wales the DWP issues NINOs. For individuals who live in Northern Ireland, the Department for Social Development (DSD) issues them.

If you come to the UK from abroad to work, you will need to apply for one.

To apply for a NINO in England, Scotland or Wales, you should telephone the Jobcentre Plus NINO service.

If you live in Northern Ireland, you can contact your nearest NINO processing centre. You can find out more on the NI direct website.
