Eurostar - Advance Passenger information (API)

From the 1st of April and for travel to/from the UK, you will now be required by the UK government to provide Advance Passenger Information (API) for every single passenger showing on your booking.

Please note: This is mandatory in order to generate your tickets.

Who needs to provide their API?

All passengers must complete the API form before receiving their tickets for travel. If only 1 passenger has completed the form on a group booking, the tickets will not be available.

API is not needed for children under 4 who travel without a ticket on an adult’s lap. For children under 4 who have a ticket booked, it is required to complete their API too.

What information do I need to provide?

You and every single passenger listed on your booking will need to provide the following information, exactly as it shown on your travel document:

Full name
Date of birth
Gender
Nationality
Travel document type
Travel document number
Travel document country of issue
Travel document expiry date

We will only accept Passport as the type of document. If you don't have a passport and use a national ID card, you will need to complete the API form directly with Eurostar.

When do I need to submit the API?

You will need to provide the API after booking and before travelling in order to collect your tickets or you won’t be able to generate them.

How do I provide the API?

You will need to provide the API from our website, the form won't be available from your app.

Registered booking:
If you made your reservation with your trainline account, you will just need to log in and submit the form from My bookings section, next to your reservation.

Guest booking:
If you made your booking without a trainline account, you can access the form directly from your confirmation email from the Manage booking link or via our Find a booking page.

Please note: The information submitted in the form will not be saved for future journeys, this must be re-entered each time.

I’ve made a typo while filling the API form

Not to worry, you can amend the details in the form as many times as necessary but you need to make sure the passenger name matches the name on your ticket.You can resend the form with the correct information directly on Eurostar website.

I’ve booked before the 1st of April

If your ticket was purchased prior to April 1st for a travel date after that day, there is no requirement for you to provide the API.

Please note: If you want to change the date, you will need to provide the API in order to get your new tickets.

I’ve provided my API but didn’t receive my ticket

If you didn’t receive your ticket you will need to contact us.
