Hello Prahoge62,
Thank you for your message.
You can change the address in your swiss pass customer account under sbb-tickets.cc/de/angebote/swisspass-karte. The address is not printed on the SwissPass card.
In case you have ordered a new SwissPass card to the wrong address, please call our contact center under the number 0848 44 66 88 (CHF0.08/Min.) to check if the card was sent back to us.
I wish you an excellent evening.
Greetings,
RahelW
