Hello kexts
As we are a customer-to-customer support forum, we are unable to help as we cannot treat requests involving personal data which is required to identify your issue.
Please kindly call the SBB Contact Center: 0848 44 66 88 (CHF 0.08/min, waiting times may occur) or seek advice with an agent in a travel centre at a station.
Changing names, e.g. after marriage or divorce, is done free of charge, and this, no matter by which channel the change has been communicated.
Kind regards,
Roland
