I want to set it on as a mobile ticket in the app, I have a SBB account but I'm unable to make a Swiss Pass account as it keeps asking for my customer number. As I only have the paper PDF, I don't see a customer number on there. I've tried the numbers that are on there with no luck.
I also wanted to reserve some seats on a Golden Pass train, which I don't know if I can do if I don't have the Swiss Pass account.
