Seatfrog accepts 13-character booking references for Classic room bookings, made via the Caledonian Sleeper website.
Where to find your 13-character booking reference
You'll find your booking reference in both the subject line and the body of the confirmation email sent out from when you made your booking on the Caledonian Sleeper website.
Once you've got your booking reference, enter it into the app along with your departure date and we'll add the auction to your account.
