National Insurance numbers in the UK: how they work and why they matter
Translated from the Arabic original. Read in Arabic
Your National Insurance number is a personal number that stays with you throughout your working life in the UK. Your National Insurance contributions are recorded against it, and they later decide your entitlement to the State Pension and some benefits.
Do you already have one?
Many people arriving on work or study visas receive a National Insurance number as part of the visa process. Check your immigration documents and your online immigration account first. If you do not have one and you have the right to work, apply through the official GOV.UK page. The service is completely free, so avoid anyone who asks for money for it.
Do you need it to start work?
You can start work before your number arrives if you can prove your right to work, but you must give it to your employer as soon as you get it so that your contributions are recorded correctly in your name.
Contributions and the State Pension
National Insurance contributions are deducted from your pay above a certain threshold. Every full year of contributions, or of credits given in situations such as registered unemployment or caring for children, counts as a qualifying year. You usually need 35 qualifying years for the full new State Pension, and at least 10 to get any State Pension.
Check your record
You can check your contribution record and a pension forecast through your personal account on GOV.UK. If you find gaps, you may sometimes be able to fill them with voluntary contributions within a time limit. Before paying, make sure it is worthwhile and get advice from the official service.
If you leave the UK
Your qualifying years stay on record, and you may be entitled to a partial pension later even if you live abroad. Some countries have social security agreements with the UK that affect entitlement. Keep your number and documents safe.
Protection tips
Only share your number with your employer, official bodies and your bank when necessary. Ignore messages and calls claiming your number has been "suspended" and asking for details or payment: they are common scams.
National Insurance and benefits
Some UK benefits depend on your National Insurance record rather than your current income, such as New Style Jobseeker’s Allowance and New Style Employment and Support Allowance. If you lose your job, your contributions in the last two tax years decide whether you qualify. That is why it matters that every employer records your contributions under the correct number.
