How children buy tickets

An adult passenger can bring a child less than 1.2m in height free of charge. If there is more than one child less than 1.2m in height, one child is free of charge, and other children should buy child tickets. If the height of children is 1.2-1.5m, please buy children's tickets; if the height is more than 1.5m, please buy full price tickets. When an adult passenger holds a sleeper ticket, the child may share a sleeper with him or her, and the ticket shall be free of charge or purchased according to the above provisions.

Certificate for children's ticket

At present, when buying real name tickets at the railway ticket window, the real name system is not applied to children's tickets. When purchasing children's tickets on 12306.cn, if children have valid identity documents, they can be added as common contacts (when children's valid identity documents are resident identity cards, only registered users with resident identity cards can add the children as common contacts); if the status of identity information verification is "passed", "please apply for inspection" and "pre passed", they can purchase tickets. If a child does not have a valid identity document, he / she can use the identity information (name, type and number of the document are the same adult) of his / her peers who have passed, applied for inspection and passed in advance to purchase tickets.
