UK ETA App Troubleshooting 2026: Fix Common Errors & Problems

The UK ETA app is designed to make applying for an Electronic Travel Authorisation quick and straightforward. However, like any technology, it can occasionally present problems that frustrate applicants. From app crashes and login issues to photo capture failures and payment errors, these technical glitches can cause unnecessary stress, especially when you have a trip to plan. This comprehensive troubleshooting guide covers every common UK ETA app problem and provides clear, step-by-step solutions to get your application back on track in 2026.

App Installation and Compatibility Issues

App Won’t Download or Install

If you are unable to download the UK ETA app from the Apple App Store or Google Play Store, check the following:

Key fact: The UK ETA costs £16 per application, is valid for 2 years or until your passport expires, and allows unlimited visits of up to 6 months each. Citizens from 48 eligible countries must obtain an ETA before travelling (Source: GOV.UK).

• Device compatibility: The UK ETA app requires iOS 15.0 or later for iPhones and Android 8.0 or later for Android devices. Older phones running outdated operating systems may not be compatible. Check your phone’s operating system version in Settings.
• Storage space: The app requires approximately 100 MB of free storage. If your phone’s storage is full, delete unused apps or files to make room.
• Regional restrictions: The app should be available in all countries, but some App Store regions may experience temporary unavailability. If the app does not appear in search results, try searching for “UK ETA” directly or visit the official UK Government ETA page for direct download links.
• Internet connection: A stable internet connection is required for downloading. Switch between Wi-Fi and mobile data to see if the download starts.

App Crashes on Launch

If the UK ETA app crashes immediately after opening or during use, try these solutions in order:

1. Force close and restart: Close the app completely (swipe it away from your recent apps list) and reopen it. This clears the app’s temporary memory and often resolves crash issues.

2. Restart your phone: A full device restart clears all background processes and can resolve app stability issues. Hold the power button, select restart, wait for the phone to fully boot, then try the app again.

3. Update the app: Check the App Store or Google Play Store for available updates. Developers regularly release fixes for known bugs and crashes. Enable automatic updates to ensure you always have the latest version.

4. Update your operating system: An outdated phone operating system can cause compatibility issues with newer app versions. Check Settings for available system updates and install them before trying the app again.

5. Reinstall the app: If the above steps do not work, delete the app completely and download it fresh from the store. This removes any corrupted data that may be causing the crash.

Passport Scanning Problems

NFC Chip Read Failure

The UK ETA app uses your phone’s NFC (Near Field Communication) reader to scan the electronic chip in your passport. This is one of the most commonly reported problem areas. If the app fails to read your passport chip:

• Check NFC is enabled: Go to your phone’s Settings and ensure NFC is turned on. On iPhones, NFC is always on and cannot be toggled. On Android, you may need to enable it manually.
• Remove phone case: Thick phone cases, metal cases, and cases with magnetic closures can interfere with the NFC signal. Remove your case before scanning.
• Position correctly: The NFC antenna location varies by phone model. For most iPhones, it is at the top of the phone. For Android devices, it is usually in the centre of the back. Place the passport’s data page (the page with your photo) face down on a flat surface, then slowly move the top (iPhone) or centre (Android) of your phone across the passport until the app detects the chip.
• Keep still: Once the app starts reading, hold your phone completely still. The NFC read takes several seconds, and any movement can interrupt the process.
• Open the passport flat: The chip is embedded in the data page or front cover. Open the passport fully and lay it flat rather than holding it partially open.
• Try different positions: If the chip is not detected, slowly move your phone across different parts of the passport’s front cover and data page. The chip location varies between passport manufacturers.

Passport Not Recognised

If the app does not recognise your passport at all (even before NFC scanning), ensure you are scanning the correct page. The app needs to read the Machine Readable Zone (MRZ) — the two lines of text and numbers at the bottom of your passport’s data page. Ensure the entire MRZ is visible in the camera frame, with good lighting and no glare on the page.

Photo Capture and Upload Errors

Photo Keeps Getting Rejected

The UK ETA app has built-in photo verification that checks your image against strict requirements. Common reasons for repeated rejection include poor lighting, incorrect positioning, glasses, and background issues. For a complete guide to fixing photo rejections, see our detailed article on UK ETA photo rejected — how to fix it.

Camera Not Working in the App

If the camera does not activate when the app asks you to take a photo:

• Check camera permissions: Go to your phone’s Settings, find the UK ETA app, and ensure camera access is granted. On iPhones, go to Settings > Privacy > Camera. On Android, go to Settings > Apps > UK ETA > Permissions.
• Close other camera apps: If another app (such as the default camera, WhatsApp, or Snapchat) is using the camera, the ETA app cannot access it. Close all other apps that might be using the camera.
• Restart the app: Force close the ETA app and reopen it. Camera access sometimes fails to initialise properly on first launch.

Photo Upload Fails

If you are uploading a pre-taken photo rather than using the in-app camera, and the upload fails, check the file format (JPEG or PNG are required), file size (between 50 KB and 10 MB), and image dimensions. Avoid uploading screenshots, as these are often lower quality than original photos.

Payment Errors

Payment Declined

If your payment is declined when trying to pay the £16 UK ETA fee, try the following:

• Check card details: Ensure the card number, expiry date, and CVV are entered correctly. Even a single digit error will cause the payment to fail.
• International payments: Some banks block international online payments by default. Contact your bank to authorise the transaction or temporarily lift any international payment restrictions.
• Sufficient funds: Ensure your card has sufficient funds or credit available for the £16 charge plus any foreign transaction fees your bank may apply.
• Try a different card: If one card is declined, try another debit or credit card. Visa and Mastercard are most widely accepted.
• 3D Secure verification: Your bank may require additional authentication (such as a code sent via SMS or approval through your banking app). Watch for pop-up windows or redirect screens during the payment process.
• VPN interference: If you are using a VPN, it may interfere with the payment gateway’s fraud detection. Disable your VPN and try again.

Charged But No Confirmation

If your card has been charged but you did not receive a confirmation, do not submit another payment immediately. Wait at least 30 minutes, then check your email (including spam and junk folders) for a confirmation message. You can also log back into the app to check your application status. If the payment was processed successfully, your application should show as submitted.

Login and Account Issues

Cannot Create an Account

If you are having trouble creating an account in the UK ETA app, ensure your email address is valid and that you have access to it (you will need to verify it). Use a personal email address rather than a temporary or disposable email service, as these may be blocked. If registration fails, try using the web-based application portal on the official UK Government website as an alternative.

Forgot Password or Locked Out

Use the “Forgot Password” feature on the login screen to receive a password reset email. Check your spam folder if the email does not arrive within a few minutes. If you are locked out after multiple failed login attempts, wait 30 minutes before trying again, as the system may temporarily block your account for security reasons.

Application Status and Processing Issues

Application Stuck on “Processing”

After submitting your ETA application, it enters a processing queue. Most applications are approved within a few hours, but some may take up to 3 working days. If your application status remains on “processing” for longer than expected:

• Be patient: The standard processing time is up to 3 working days. Weekends and UK bank holidays are not counted as working days.
• Do not submit duplicate applications: Submitting multiple applications for the same person can cause confusion and further delays. Wait for your original application to be processed.
• Check your email: The UK Home Office may contact you requesting additional information or documentation. Check your email regularly, including spam and junk folders.
• Contact support: If your application has been processing for more than 5 working days without any communication, contact the UK ETA support team for an update.

Application Shows Incorrect Status

If your application status appears incorrect (for example, showing as “draft” when you believe you submitted it, or showing an old application instead of a new one), try logging out of the app completely and logging back in. The app may need to sync with the server to display the latest status. If the issue persists, clear the app cache (Android: Settings > Apps > UK ETA > Storage > Clear Cache) or reinstall the app.

Network and Connectivity Issues

App Times Out or Shows Network Errors

The UK ETA app requires a stable internet connection throughout the application process. If you experience timeout errors or network-related messages:

• Switch networks: Try switching between Wi-Fi and mobile data. Some Wi-Fi networks (particularly public or hotel Wi-Fi) may have firewalls that interfere with the app’s connection.
• Check signal strength: A weak mobile data signal can cause intermittent connectivity. Move to an area with better signal coverage.
• Disable VPN: VPN connections can sometimes interfere with the app’s servers. Disable your VPN temporarily during the application process.
• Try at a different time: Server load can vary throughout the day. If the app is consistently failing, try again during off-peak hours (early morning or late evening UK time).

Alternative: Apply Online Without the App

If you continue to experience problems with the UK ETA app, remember that you can also apply for the UK ETA online through the official government website using any web browser on your phone, tablet, or computer. The web-based application process is functionally identical to the app and may resolve issues related to app compatibility, camera access, or NFC scanning.

The web portal allows you to upload a pre-taken photo and enter your passport details manually, bypassing the in-app camera and NFC scanning features that cause the most common technical issues.

Frequently Asked Questions

The app says my passport chip cannot be read. What should I do?

First, ensure NFC is enabled on your device and remove any phone case. Try positioning your phone at different angles over the passport data page and front cover. If the chip still cannot be read, your passport’s chip may be damaged. In this case, use the web-based application at gov.uk/eta where you can enter passport details manually instead of using NFC.

I accidentally submitted incorrect information. Can I correct it?

If you notice an error after submitting your application, you should contact the UK ETA support team as soon as possible. Minor errors (such as a typo in your email address) can usually be corrected. However, if the error involves your passport number or personal details, you may need to submit a new application. Do not travel with an ETA that contains incorrect passport information, as it will not be matched to your passport at border control.

The app is not available in my language. Can I still use it?

The UK ETA app is currently available in English and several other languages. If your preferred language is not supported, you can use a translation app alongside the ETA app, or apply through the web portal where browser-based translation tools can help. All official communications about your application will be in English.

My application was approved but I cannot see the confirmation in the app.

Check your email first, as confirmation is also sent by email. If the app is not showing your approved status, try logging out and back in, or check for app updates. Your ETA is linked to your passport electronically, so even if the app display is incorrect, border authorities will be able to verify your ETA through their systems when you travel.

Can I use the app on a tablet instead of a phone?

The UK ETA app is designed for smartphones and may work on tablets, though the experience may not be fully optimised. The key requirement is that the device must have an NFC reader for passport scanning (not all tablets have NFC) and a camera for the photo capture feature. If your tablet lacks NFC, use the web-based application instead and enter your passport details manually.
