China Train Tickets for Children: Ages, Free-Child Registration and Passports
Last checked: 28 September 2026. This guide concerns domestic mainland China rail journeys; check the separate conditions for international and Hong Kong cross-boundary services.
For a family booking trains in China, three decisions come before choosing a departure: the child's age on the travel date, whether the child needs a separate seat, and which document identifies that child. A free ride is not the same thing as an unregistered passenger, and an adult's passport is not a substitute for the child's own document.
This guide helps you build the correct family booking, including the awkward cases: one adult with two preschoolers, a birthday between outward and return journeys, and a free child whose details have not been added to the order. For station navigation and the wider booking process, use our foreign-passport high-speed rail guide.
Start with age on the day of each journey
| Traveller | What to arrange | Seat implication |
|---|---|---|
| Under 6, one child accompanying one ticketed adult | Free-child declaration if not occupying a separate seat | No separate seat entitlement |
| Under 6, but you want a separate seat | Child discount ticket | Book the required accommodation rather than relying on an empty seat |
| A second under-6 child accompanying the same sole adult | Child discount ticket for the additional child | The one-free-child allowance cannot cover both |
| Age 6 through 13 | Child discount ticket | Match the accompanying adult's train and class |
| Age 14 or older | Full-price ticket | Select the required accommodation |
These are age rules, not the old height thresholds still repeated in older travel answers. The current 12306 child-ticket FAQ also requires children under 14 to travel with an adult, apart from narrowly defined exceptions.
Birthday example: if a child turns six during your holiday, assess the outbound and return dates separately. Do not simply copy the first booking's passenger category into the second. Put the dates of birth next to the travel dates in your planning notes before you start buying tickets.
Decide about a seat before paying
Think about what your child will actually do during the ride: sit with you, nap, eat a meal or need space for an activity. For a longer journey, compare the actual child-ticket quote with the practical cost of sharing one seat throughout. This is a comfort decision, not a reason to misstate a birthday.
Applying Article 15 of the railway's passenger conditions, one adult travelling with children aged three and five cannot declare both free against that adult. Two ticketed adults, each accompanying one eligible child, present a different allowance calculation. Work through the people travelling on that particular train, not everyone in your holiday group: an adult on another departure does not help with this booking.
Do not plan around finding an unoccupied seat after departure. Check the accommodation shown on the issued order, including any no-seat designation. If adjacent seats matter, review the assigned seats before treating the journey as settled; a booking request is not proof that your family has been placed together.
Also avoid budgeting with a universal “half-price child fare.” The railway's published discount calculation varies by accommodation and includes additional conditions. Use the price returned for your selected train, passenger and class. For an overnight journey, consult the sleeper-train booking guide rather than applying a daytime-seat assumption to a berth.
Create a passenger record using the child's own passport
For a foreign-passport family, have each child's original passport available while entering the passenger details. China Railway's official child-travel explanation explicitly includes foreign passports among valid documents and requires the child's own document for both paid child travel and free-child travel.
- Add the child as a passenger, using the correct document type, passport number and name.
- Check every character against that passport. Do not use a nickname or insert the parent's details to get past a form.
- Follow the verification prompts shown for that passenger. If the form cannot handle your document or name, resolve the problem through the railway before booking a tight itinerary.
- For a paid child ticket, select the appropriate child category and book the same travel date, train and class as the accompanying adult; the child's destination cannot be beyond the adult's.
The 12306 booking FAQ distinguishes passenger verification statuses and warns that a purchased ticket's name cannot simply be edited. A wrong identity entry may require refunding and buying again under the applicable rules. Check before payment, especially if a browser has autofilled another family member's name.
Register the free child against the adult's journey
On the Chinese app, the railway's published sequence is to add the child to the passenger list first, then use the paid adult order to add a free child. Look for 添加免费乘车儿童, meaning “add a child travelling free.” Interface wording and screen placement can change, so follow the current prompts rather than an old screenshot.
After submitting, check that the intended child is associated with the intended adult and departure. Saving a passenger in your account is not the same as declaring that passenger on a journey. If you missed the declaration during booking, the railway directs passengers to arrange it at a station ticket window before travel.
A useful family check is to read the order aloud: adult, child, date, train and destination. Repeat this after changing travel plans. Keep a saved order reference for finding the booking, but bring the original passports: a screenshot is not the travel identity document.
At the station: solve document problems before the boarding rush
Keep the whole family's passports together and accessible, not buried in a suitcase. Allow extra time if you still need a ticket-window service. If the automated reader cannot process the child's document, seek the staffed channel rather than repeatedly trying the same gate. The railway's child FAQ describes manual verification when the automated process cannot identify a passenger.
Do not arrive assuming the published train departure is the last possible entry time. Station gate closure is earlier and locally announced; leave room for document checks, security and finding the right waiting area. A free child still adds practical work at each stage, even when there is no separate fare.
Keep the essential bag small enough that one adult can manage documents without abandoning luggage. Before adding a stroller, large case and several bags, check our China train luggage planning guide. Avoid turning a document-check delay into a scramble to redistribute bags.
A final five-point check before leaving the hotel
- Every child's age category matches this journey's date.
- Any required child ticket is issued, with the intended accommodation.
- Every free child is declared, not merely saved in the account.
- Each original passport matches the details used for travel.
- The family has checked the station name, departure and order again after any changes.
If a child's passport is missing or the identity details are wrong, contact the railway promptly. Do not assume procedures for issuing temporary identification to Chinese resident-ID holders apply to a visiting foreign child. Resolving that specific document problem takes priority over reaching the platform quickly.
