How to apply

To get a National Insurance number you need to apply online. You’ll need to prove your identity when you apply.

What documents you’ll need

If you have any of the following documents, get them ready before you start:

  • a passport from any country
  • a biometric residence permit (BRP)
  • a national identity card from an EU country or from Norway, Liechtenstein or Switzerland

You might need to enter information from one or more of these documents.

You can still apply if you do not have any of these documents, but you may need to attend an appointment in person to prove your identity.

Prove your identity

If you can, you’ll need to take and upload:

  • a photo of yourself holding your passport
  • photos of other identity documents

You can use a smartphone, tablet or a digital camera.

You’ll be told how to take the photos and what they must look like during the application process.

You can ask someone to take the photos for you.

If you cannot upload photos

You can still apply online but your application will take longer.

You may need to attend an appointment or post photocopies of your documents. You’ll get an email telling you what to do after you’ve submitted your application.

It can take up to 4 weeks to get your National Insurance number after you’ve proved your identity.
