Do Children Need Their Own Train Tickets in China?

Your child may be young enough to travel free, but that does not mean they have a seat—or that you can leave them out of the travel arrangements.

For mainland China's real-name railway services, children aged 6 to under 14 need a child-discount ticket; those aged 14 and above need a full-price ticket. One ticket-holding adult can bring one child under 6 free only if the child does not occupy a separate seat or berth. An under-6 child who needs their own place needs a child ticket. Age is measured on the travel date. 12306 ticket-purchasing notice

This article focuses on accompanied family journeys within mainland China, including high-speed trains. Do not apply it automatically to city metros, international trains or Hong Kong cross-boundary bookings.

Start with age, then decide about the seat

For example, one adult travelling with two under-6 children cannot take both free: the additional child needs a child ticket. A birthday between your outward and return journeys can change the ticket category. 12306 purchasing conditions

Does a child travelling free still need to be registered?

Yes. Declare the child to the railway when arranging the booking. The valid identity document used for that declaration serves as the child's travel credential; bring it for checks. Free travel is not permission to bring an undeclared extra passenger. The rules also require the child's discounted ticket to match the accompanying adult's date, train and accommodation class, with a destination no farther than the adult's. 12306 passenger regulations, Articles 15 and 24

Our practical recommendation: before considering the family's booking complete, check each person individually. For the child travelling free, confirm the declaration has been recorded. For a child with a seat, check the issued ticket and seat details. Do not rely on a note typed into a third-party booking request unless the seller confirms the railway arrangement.

What should a foreign-passport family bring?

Use the child's own valid passport for their passenger details, and carry the original document used for the booking or free-child declaration. Current Chinese-language guidance explicitly requires a child's own valid identity document for child-ticket purchases. 12306 children's tickets FAQ

12306's English service accepts valid foreign passports. Its general booking guidance explains adding other travellers to the passenger list with accurate names and document details. However, some older child-related passages on that English FAQ still refer to height-based rules and adult identity details. Do not use those passages to override the current child-ticket requirements. 12306 English FAQ

We have not tested every app version or third-party foreign-passport workflow. If the child cannot be added or declared, ask the railway ticket counter or your ticket seller to resolve it before boarding; do not substitute the adult's passport details merely to get past an input field.

Are children's tickets always half price?

No. The current 12306 FAQ distinguishes ordinary-train seats and berths, several high-speed seating categories, and high-speed sleepers. It also specifies minimum-fare conditions. Check the quoted child fare for the actual service rather than halving the adult price yourself. A separate sleeper berth should not be budgeted as an ordinary half-price seat. 12306 child-fare rules

Should you buy a seat for an under-6 child?

That is a comfort decision as well as a ticket decision. Consider journey length, how comfortably you can share your space, and how much you will be managing while travelling. An empty nearby seat is not a reserved place for your child.

If you buy seats, inspect the actual allocation rather than assuming that one family order necessarily means adjacent seats. Raise any separation with the seller or railway staff before boarding where possible; do not build your plan around another passenger agreeing to swap.

Your final family booking check

• Check each child's age on each travel date, including the return journey.
• Confirm whether each child is travelling free or on a purchased ticket.
• Confirm the free-child declaration or the issued seat/berth details.
• Pack the original passports used for the arrangements.
• Keep the family's train and passenger information together for easy reference.
