How do I get a National Insurance number?
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.
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.
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.
We provide more information on how to get a National Insurance number in our migrants guidance.
Who needs to know my National Insurance number?
The following people may need to know your National Insurance number (NINO):
- employers and pension providers
- local council
- the Student Loans Company
- banks and building societies.
Do not give your NINO to anyone who does not need to know it.
What do I do if I lose or forget my National Insurance number?
If you lose or forget your National Insurance number (NINO), you may be able to find it on official documents, for example, payslips from a job, your tax return, or a PAYE coding notice.
It is also possible to ask HMRC to confirm it by:
- completing form CA5403 ‘Your National Insurance Number’ and sending it to HMRC; or
- contacting the National Insurance numbers helpline if you are in England, Scotland or Wales, or the National Insurance Registration helpline if you are in Northern Ireland.
Whichever method you use, HMRC will write to you and confirm the NINO. They will not provide the NINO over the telephone.
