Step-by-Step Instructions
Follow these verified steps in order to complete your setup.
Check If Your BRP/eVisa Already Has an NI Number
Look at the back of your Biometric Residence Permit (BRP) or your digital eVisa profile. Skilled Worker visa holders often have an NI number automatically assigned and printed on the card.
Submit the Online DWP Application
If you do not already have one, go to the official GOV.UK portal (gov.uk/apply-national-insurance-number). It takes about 10–15 minutes to enter your personal details, arrival date, and immigration reference.
Upload Photos of Your Passport and Face
You will receive an email link to the DWP identity verification tool. Take clear photos of your passport bio-page and a selfie.
Receive Your NI Number Letter by Post
DWP will post your official confirmation letter to your UK address within 2 to 4 weeks. Give this number to your employer’s payroll department.

Essential Money-Saving Tips
Smart tricks to minimize your expenses
- NEVER pay third-party websites that claim to "fast-track" your NI number for £30–£70. The application is completely free on GOV.UK, and third-party companies cannot speed up DWP processing.
- Check your payslips: once your NI number is registered, HMRC will automatically rebate any excess emergency tax paid on your subsequent paychecks.
Common Mistakes to Avoid
Pitfalls new arrivals frequently encounter
- Refusing to start a job offer because your NI number has not arrived yet (employers are legally required to onboard you with proof of right to work alone).
- Falling for telephone or text scams claiming "Your National Insurance number has been suspended due to fraudulent activity". DWP never suspends NI numbers.
