To contact SBB (Swiss Federal Railways) regarding your SwissPass in 2026, the most direct method is calling the SBB Contact Center at +41 848 44 66 88. This line is available 24 hours a day (CHF 0.08/min within Switzerland). For those who prefer digital interaction, the SBB website and mobile app now feature an AI-powered "SBB Chat" assistant that can handle common queries about travelcards, Half Fare Travelcard PLUS, and account deposits. If the chatbot cannot resolve your issue, you can request a transfer to a live customer consultant during business hours. Additionally, you can visit any SBB Travel Centre in person at major stations like Zurich HB or Geneva for a consultation. For social media users, SBB is quite active on X (formerly Twitter) and Facebook, though these are better for general information rather than specific account-related issues requiring personal data verification.
