Do I Need to Print My UK Electronic Travel Authorization (ETA)?
No, you do not need to print your UK Electronic Travel Authorization (ETA).
Your ETA is electronically linked to your passport and will be automatically checked when you travel.
However, it’s a good idea to keep a digital copy (such as a screenshot or saved PDF) on your phone or device in case you're asked to show confirmation during your journey.
Make sure the passport you travel with is the same one you used to apply for your ETA. If you
get a new passport, you will need to apply for a new ETA
For the latest travel requirements and guidance, always check the official UK government website before you travel.
