Information on who pays National Insurance, why you pay it and how
National Insurance Registrations Helpline
The helpline provides advice to young people aged between 15 years and 9 months and 20 years old who haven't received a National Insurance number.
They can also help if you've lost or can't remember your National Insurance number or lost your National Insurance number card and issue letters of confirmation of National Insurance numbers.
HMRC no longer issue National Insurance cards. You don't need to have a card – it's the number that's important. If you can't remember your number, find out what to do by following the link at the top of the page 'Applying for a National Insurance number'.

For customers who are deaf or hearing or speech impaired:
0300 200 3519 (Textphone)
A textphone allows you to type what you want to say rather than speaking into a mouthpiece. You can use a textphone instead of a voice telephone if you are deaf or have problems with your speech. It is not possible to speak to an adviser by phoning a textphone number.
We cannot allocate National Insurance numbers, arrange appointments with the Department for Work and Pensions to apply for a National Insurance number or confirm a National Insurance number over the telephone.
