What Do 12306's Terms Actually Mean?

What’s the short answer?

12306 is China Railway’s own official ticketing platform — the same system the station counters use — and its odd English labels are literal translations of railway jargon. The words confuse foreigners precisely because they are official terminology, not a scam’s broken English: “endorsement” means changing your train, “verification” means the passport check on your account. Decode the vocabulary once and the app becomes usable.

Is 12306 legit?

Yes — it is the official platform of China Railway, with no equivalent. The English site sells the identical e-tickets as the Chinese app and the station counters, accepts foreign passports, and takes international cards (since 2024). Trip.com and other agencies are authorised resellers fronting the same inventory with better English support, at a small service fee. When a train “sells out”, it has sold out on 12306 itself — resellers have no secret inventory.

What is “endorsement” on 12306?

It is 12306’s translation of gaiqian — changing your train. Per the official English FAQ: “endorsement refers to the procedures to take when passengers change the date of travel, train number, or seat (berth).” The boundaries matter: you cannot change the departure or arrival stations (same-city stations excepted), it can be done only once per ticket, and a ticket endorsed after train departure cannot be refunded. Missed your train already? That’s the missed-train rescue procedure. The full term-by-term breakdown: what “endorsement” means on 12306.

What is “verification”?

It is the one-time check that your passport and account details match, before your first ticket. 12306 verifies the passport number you registered; this can pend for hours on first use, which is why you should register days before you need a ticket tonight. The full booking flow is in our trains guide.

What is the “waiting list”?

It is 12306’s official waitlist: when a train sells out, you can register a candidate order and the system assigns you a seat automatically if one is released by cancellations. It works for foreign passports on the English app, and it is how locals hold a place in sold-out Golden Week queues. If it never clears, nothing is charged. Resellers offer the same mechanism through 12306 behind the scenes.

What do the train prefixes and seat classes mean?

The letter is the speed tier, the seat classes are fixed price tiers. G (gaosu) is the fastest high-speed service, D (dongche) is a slightly slower bullet train, C (chengji) intercity lines; Z, T and K are conventional overnight/express trains with sleepers. On G/D trains: business class (1+2 seats), first class (2+2), second class (2+3, the standard pick), and no-seat standing tickets at second-class price.

When can you actually buy or change tickets?

Sales and changes run 5:00 to 1:00 the next day — 5:00 to 23:30 on Tuesdays — while information queries and refunds work 24 hours. This quirk is in 12306’s own FAQ and trips up first-timers trying to book a train at 2 a.m. for that morning. Tickets open ~15 days before departure on 12306 (14 on Trip.com), and the popular routes sell out in minutes on Golden Week dates.
