National Insurance Number

To apply for a NATIONAL INSURANCE ( NI) NUMBER, please call 03456000643

Your National Insurance (NI) number is a unique reference code which records NI contributions and credits to your NI account. The Contributions agency and Inland Revenue use this to file the information, which they hold on you.

If you work and you are a student you are liable to pay income tax and National Insurance contributions on your earnings.

Overview

A National Insurance number is made up of a combination of letters and numbers – two letters, six numbers and then another letter,

For example: J Z 56 27 96 D

Every UK citizen is issued with a National Insurance number at birth and the number is sent out shortly before an individual turns 16. The number can be found on documents such as P45s, P60s, wage slips and other correspondence from the Inland Revenue.

Keep your number safe and do not disclose it to anyone who does not need it, its purpose is only to record NI contributions and credits paid or entitled to.

Know your NINO!

You should tell your employer your National Insurance Number (NINO) when you start work. Always quote your NINO correctly. Using the correct NINO will make sure the National Insurance contributions that you pay are recorded against your name and will also help you pay the right amount of tax.

Do I have to pay it?

Your employer should deduct National Insurance contributions from your earnings whenever you earn above a certain level. CLICK HERE to view the current rate 

Can I claim it back?

For National Insurance, your earnings are looked at weekly or monthly rather than annually like income tax. Unless your employer has incorrectly deducted National Insurance contributions based on the above limits, you cannot obtain a refund.

What about working for myself/running my own business?

If you are running your own business you need to register with HMRC for self employment and National Insurance contributions within 3 months of starting your business. You will pay tax on profit you make in excess of your Personal Allowance. To see if you have exceeded your Personal Allowance you also need to take into account anything you earn from working in a job for someone else.

Lost Numbers

If you have a number but cannot remember it, you can find it on any official papers you may have at home, have a look out for any of the following:

  • An end of year statement of tax and NI paid (P60)
  • Old pay slips
  • Official correspondence
  • Employers wage records

The number will not change, even if you go abroad, marry or change names. If you are still unable to find your number, you’re nearest Social Security office or Inland Revenue (NI Contributions) office will tell you what to do. You will need to complete an application form, but only one replacement card is allowed.

For more information you can phone the National Insurance Enquiry Line on 0345 600 0643.

Any change in details, such as title, name or address should be notified to the Contributions Agency so that their records can be kept up to date.
