Hello Ballinold58
Just keep in mind:
Even if your ticket’s ID is trustful and confirmed by SBB, you cannot be sure the ticket is still valid at the time of travel.
We therefore suggest purchasing Swiss Travel Passes from trustful sources only, STC or SBB being two of them. And, should you need help with your passes while staying in Switzerland, you can talk to a local representative which you can’t when purchasing from resellers located somewhere abroad.
Kind regards,
Roland
