How to Get a National Insurance Number as a New Migrant (2026)
Quick answer: Apply for a National Insurance number free online at gov.uk once you’re in the UK and have the right to work or study. You’ll need your passport or Biometric Residence Permit, and most applicants now verify their identity digitally through the GOV.UK ID Check app rather than attending an in-person interview. Processing typically takes 2 to 4 weeks if verified digitally, or longer if an interview is needed. You can start working before your number arrives — just tell your employer you’ve applied.
A National Insurance number is one of the first practical things a new migrant needs to sort out, since it’s tied to paying tax correctly, building entitlement to the State Pension, and being properly recorded in the UK’s tax and benefits system. The process has become considerably simpler and more digital in recent years, so it’s worth knowing what to actually expect.
What Is a National Insurance Number?
Your National Insurance number (NINO) is a unique, permanent reference used by HMRC and the Department for Work and Pensions to track your tax and National Insurance contributions throughout your working life in the UK. It follows a fixed format of two letters, six numbers, and a final letter (for example, QQ123456C), and physical National Insurance cards are no longer issued — your number is something you look up digitally rather than carry as a card.
Who Needs to Apply?
You need a National Insurance number if you’re planning to work in the UK, are already working, or want to claim certain benefits or student finance. You must be in the UK and have the right to work or study here before you can apply.
How to Apply
- Go to the official application page at gov.uk/apply-national-insurance-number. The application is free — avoid any third-party website that charges a fee for this service.
- Confirm your eligibility — the online service checks that you’re currently living in the UK and have the right to work or are actively seeking work.
- Verify your identity — most applicants now do this digitally, typically using the GOV.UK ID Check app to scan a passport or Biometric Residence Permit and verify your identity via a face scan, rather than attending an interview.
- Submit your application — once your identity is verified and the form is complete, you’ll receive a confirmation email with a reference number.
- Attend a Jobcentre Plus interview, if required — this is now needed only in a minority of cases where identity can’t be verified digitally, rather than as standard for every applicant.
What Documents Do You Need?
- Your passport, Biometric Residence Permit (BRP), or national ID card
- Proof of your UK address (if requested)
- Evidence of your right to work or study in the UK
How Long Does It Take?
If your identity is verified digitally, you can typically expect your National Insurance number within 2 to 4 weeks. If an in-person interview is needed, the process can take longer — allowing up to around 8 weeks from application to receiving your number is a reasonable expectation in that case.
Can I Start Work Before My Number Arrives?
Yes. You don’t need to wait for your National Insurance number before starting a job. Tell your employer that you’ve applied and provide your application reference — they can process your pay using a temporary reference in the meantime, and update it once your actual number comes through. Delaying starting work until your number arrives isn’t necessary and isn’t required by law.
Where to Find Your Number Once You Have It
Since physical NI cards are no longer issued, you’ll typically receive your number by letter, and can also find it in your Personal Tax Account on GOV.UK, the HMRC app, on your payslip once your employer has it on file, or on official letters from HMRC or the Department for Work and Pensions.
