Hello, my husband and I will be traveling from Munich to Paris, and when trying to make a seat reservation through the rail planner app it guides me to make a seat reservation via the the SNCB website https://travel.b-europe.com/eurail-ge/en/booking#TravelWish, once I fill all the information in it asks for my pass cover number, I can't seem to find that number anywhere. I found this website https://www.eurail.com/en/book-reservations#/generatePassCoverNumber that can generate a pass cover number but I don't know how or where to find my mobile pass number. I looked through the confirmation email when I purchased the passes but it's not showing a “mobile” pass number that is 6 characters long and can contain numbers and letters.  The numbers I see within the confirmation email include: Order Number, & Pass Number, mind you it’s not stating its a “mobile” pass number. Within the Rail Planner app, I can view the pass reference (which is the same as the pass number on the confirmation email) & the ID number (9 digit number). Hope someone can help, we leave in 3 days to Europe. Thank you so much.
