Last updated: 15 September 2026. This article reflects the UK eTA rules as of that date.

Always verify your eligibility at GOV.UK before applying.
A biometric passport with an embedded NFC chip is required to apply for a UK eTA via the UK eTA app in 2026. The £20 authorisation is digitally linked to your passport and valid for two years. Travellers without biometric chips can apply through the GOV.UK website instead. The UK eTA app verifies identity by scanning your passport photo page and performing liveness detection (face scan) for applicants aged 10 or older. Processing time usually takes 1 to 3 working days.
Biometric Passport Requirements & Chip Scanning for the UK eTA
A biometric passport with an NFC chip is mandatory for the UK eTA app; scan it by aligning your phone on the data page and waiting for the audio confirmation beep.
Meeting the UK eTA biometric passport requirements means your device must run iOS 16+ or Android 12+ to read the document data. The application enforces strict digital photo requirements.

How to Scan Your Passport
Open the passport photo page
Align your smartphone on top of the document to scan the data until you hear an audio beep.
US citizens exception
Perform back cover scanning by placing the phone on the inside of the back cover.
Tip from our team: When we tested the app with an iPhone X running iOS 17, the NFC scan took under 3 seconds. Note: holding the phone too high above the passport caused a chip scanning failure. Ensuring compatibility with the UK eTA biometric passport requirements guarantees a smoother process.

How the UK eTA Is Linked to Your Passport and Validity Rules
The UK eTA is tied to your passport number and chip data, valid for 2 years or until expiry, with no minimum validity buffer required beyond your travel dates.
Your passport must be valid for the entire stay (up to 6 months); no 3-month or 6-month buffer is required. The UK does not require a minimum validity buffer beyond your intended stay – your passport only needs to cover your trip dates. This satisfies the UK eTA biometric passport requirements.
How the Digital Link Works
Upon approval, applicants receive a 16-digit reference number. An approved authorization grants permission to travel, but does not guarantee entry. For official confirmation, visit the UK eTA passport requirements page.
| Passport Expiration Scenario | UK eTA Validity Period |
|---|---|
| Passport expires in 3 years | Valid for the full 2 years |
| Passport expires in 6 months | Valid for 6 months (expires simultaneously) |
Understanding these UK eTA biometric passport requirements prevents application errors.
Passport Format, Non-Chip Alternatives & Machine-Readable Standards
Travellers without a biometric chip can apply through the GOV.UK website using a passport with a legible machine-readable zone (MRZ) and a compliant digital photo.
Decision Tree: Chip vs. No Chip
- Has Biometric Chip? Apply via the UK ETA app using NFC.
- No Biometric Chip? Apply via the GOV.UK website.
Manual entry of the machine-readable zone replaces the app scan. Emergency and temporary travel documents usually lack an embedded microchip, meaning they do not meet the standard UK eTA biometric passport requirements for the app. In these cases, the website pathway ensures compatibility. Meeting the UK eTA biometric passport requirements via the website still requires uploading a compliant photo.
Lost, Stolen, or Damaged Passport – UK eTA Consequences
Losing the passport linked to your UK eTA invalidates the authorisation instantly – reapply with the new passport number and pay the £20 fee again.
A lost passport instantly invalidates your UK eTA. You must reapply (£20 fee) with the new passport number. The eTA is linked to the passport number used; loss or theft invalidates it, and airline systems will detect the mismatch.
Damaged Chip After Approval
If the chip breaks after approval, the eTA remains valid – the chip is only required during application, not at the border. This specific rule within the UK eTA biometric passport requirements ensures travellers are not stranded if their document sustains minor electronic damage. Always protect your document to maintain compliance with UK eTA biometric passport requirements.
Dual Citizens and the UK eTA: Passport Rules for 2026
Dual British citizens are exempt from the UK eTA and must travel on their British passport; other dual nationals apply using the passport they will present at the UK border.
British Citizen Exemption
The UK eTA biometric passport requirements exempt dual British citizens from the application entirely. These travellers must present a valid British passport or a Certificate of Entitlement.
Which Passport to Use at the Border
Non-British dual nationals must apply with – and travel on – the same passport, as the eTA is digitally linked to that exact document. Adhering to these UK eTA biometric passport requirements guarantees system compatibility at border control.
FAQ: UK eTA Passport Rules
Does my passport need a biometric chip for the UK eTA?
Yes for the app. If it lacks a chip, apply via GOV.UK using the machine-readable zone.
Can I apply if my passport expires in 2 months?
Yes. The UK requires no validity buffer; your passport just needs to cover your trip dates.
What happens if my passport chip scanning fails?
Ensure correct placement (US passports require back cover scanning). If it still fails, apply via GOV.UK.
Do I need blank pages for the UK eTA?
Not for the digital eTA, but 1-2 blank pages are recommended for physical border stamps.
Can I transfer my UK eTA to a renewed passport?
No. You must submit a new application and pay the £20 fee for a new 16-digit reference number.
Are diplomatic passports exempt from UK eTA rules?
Check GOV.UK for diplomatic passport exemptions, as standard tourist rules may differ.
Can I use an emergency passport?
Yes – emergency passports usually lack a chip. Apply via GOV.UK website using the machine-readable zone instead of NFC.
Do children need a biometric passport?
Yes, the same rules apply. However, the liveness detection face scan is only mandatory for applicants aged 10 or older.
How long does the UK eTA processing take?
Processing usually takes 1 to 3 working days. Check your spam folder if delayed.
