How to change ticket for different date?

Caugeewau81

I accidentally purchased a ticket for a week earlier than I was meant to. How do I go about changing my ticket to a week later? Cant see anything under orders or on website. The ticket is from Vienna to Switzerland

Hello Caugeewau81

If you bought the ticket on sbb.ch and if it is refundable, call the Contact Center of the SBB with this number or visit a ticket office if you live in Switzerland:

0848 44 66 88 (24/7, waiting times may occur)

From a foreign country the number is: +41 51 225 78 56

Kind Regards
