Changing your Deutsche Bahn seat reservation

You can change your seat reservation if you hold print-at-home or mobile Deutsche Bahn tickets. For information on finding your seat reservation on your ticket, please see Understanding your German train ticket.

If you've booked a Sparpreis Europa ticket (also called London Saver) issued by Deutsche Bahn, it isn't possible to amend the seats online for the Eurostar leg of your journey. However, you can change your seats in person with Eurostar staff at the station.

To change your domestic Deutsche Bahn seat reservation, please follow these steps:

Find your six-character PNR, located in your Rail Europe booking reference and on your DB ticket:

Go to Deutsche Bahn's page for managing your booking, and enter your PNR and the surname of the lead passenger. Click "search".
You'll see your journey details. From there, follow the instructions to change your seat reservation

Confirm the reservation details and click "Search". Select the same train and class you've already booked and click "Reservation". You don't have to sign up for a Deutsche Bahn account, just continue by clicking "Book without registering".
Follow the prompts for seat preferences and then click "Proceed". You'll then be able to choose specific seats from a seat map:

Once you've proceeded, you'll be asked to confirm the details. It is free to change your seat reservations. Your original reservation will be marked as cancelled, and you'll need to confirm the new reservation.

Deutsche Bahn will email you a confirmation of your new seat reservations, which will include a new ticket and PNR. Your original ticket and PNR will be invalid and cannot be used for travel.
Note that the seat numbers that are displayed in your Rail Europe account will not change. You'll need to refer to the tickets to find your seats on the day.
