Documents Needed for National Insurance Number UK
What documents do I need for an NI number application?
To apply for a National Insurance number, you will need documents to prove your identity and your right to work or study in the UK. The specific documents depend on your immigration status.
Identity documents (passport or ID card)
You need a valid identity document. The most commonly accepted documents are:
- UK passport (British citizens)
- Foreign passport (EU and non-EU citizens)
- EU national identity card (some countries accepted)
- Biometric Residence Permit (BRP)
Your identity is verified through the GOV.UK ID Check app, which scans your document and takes a photo of you for comparison.
Right to work documents
You also need to prove your right to work or study in the UK. Accepted evidence includes:
- UKVI share code for EU citizens with Settled/Pre-Settled Status
- Work visa vignette in your passport
- Biometric Residence Permit showing your visa conditions
- Student visa details (for international students)
- British citizen — a UK passport is sufficient
The GOV.UK ID Check app
The GOV.UK ID Check app is the primary way HMRC verifies your identity. After submitting your application, you will be directed to download and use this app. It works by:
- Scanning the NFC chip in your passport or BRP (similar to contactless payment)
- Taking a photo of your face for biometric matching
- Checking that your identity document is valid and not expired
The app is available for both iOS and Android and is free to download.
What if I do not have a passport?
If you do not have a valid passport, you may still be able to apply. Alternatives include:
- A Biometric Residence Permit (BRP)
- A valid UK driving licence (partial identification)
- Contacting HMRC directly for an alternative verification process
Our team can advise on the best approach if you do not have a passport.
