Quick Answer
For intercity travel in China, carry your original passport.
Official guidance for foreign travelers says the original valid identity document used to buy the ticket is used for railway station entry, exit, and boarding verification. In practice, your passport is one of the most important transport documents you have.
When You Definitely Want the Original
Carry the original passport when:
- taking intercity trains
- flying domestically
- checking in to hotels
- handling ticket or identity problems
A copy can be useful for backup. It is not a full replacement in these situations.
Why This Matters More in China Transport
Many transport systems in China are tightly linked to real-name ticketing and identity verification.
That means the passport is not just a general travel document. It is often the document that connects:
- your booking
- your station or airport access
- your boarding eligibility
If the original is missing, a screenshot of the booking usually does not rescue the situation.
When a Copy Still Helps
Keeping a photo or paper copy is still smart because it helps if:
- you need to show basic ID information quickly
- your passport is stored safely at the hotel for a short local errand
- you need a reference for numbers and spellings
But do not confuse convenience with legal equivalence.
A Good Practical Rule
For local neighborhood activities, you may not always need to carry the passport on your body.
For transport days, arrival days, check-in days, or any day involving tickets and official counters, bring the original.
If you are taking a train out of town, changing hotels, or heading to the airport, do not overthink it. Just bring it.
Practical Checklist
- I know train and flight days are passport days.
- I keep a backup copy or photo.
- I do not assume a copy can replace the original for boarding or formal verification.
- I treat hotel-change days and ticket-problem days as passport days too.
