Foreign travelers can purchase high-speed rail tickets via the 12306 official website/APP or station windows. An account must be registered in advance, with passport information verification required (online verification takes 3-5 working days; on-site verification at stations is instant). Refunds and ticket modifications support passport-based operations, and e-tickets allow direct entry by swiping the passport—paper tickets may be needed for some routes. For assistance with ticket booking, fast-track verification, or multilingual support, contact service@intotravelchina.com for one-stop solutions including itinerary planning, transfer services, and emergency backup.
