WHAT TO BRING
To check in, you will need your Eurostar ticket, plus a valid passport or identity card, and a visa if applicable. If you're travelling with kids, they will need their own passport too, including babies.
When you arrive at the check-in gates, simply scan the barcode on your paper ticket or on your mobile. It's very simple! If your ticket doesn't have a bar code, don't worry - you just need to check in at one of the desks.
When you're departing from a UK station, bear in mind that extra passport checks are done but these only take a few seconds.
