1. First of all, this authentication is to verify the authenticity of the identity information of common contacts, which is automatically completed by 12306 website without public participation.
2. Secondly, the identity information of registered users and common contacts who use the second-generation resident ID card on 12306 website will produce three results after authentication: passed, to be verified and failed. Passports, Hong Kong and Macao residents' passes to and from the mainland, registered users and common contacts in Taiwan residents' passes to and from the mainland will have four verification statuses: passed, requested for inspection, pre-passed and failed.
3. Among them, registered users and common contacts who have passed and pre-passed can handle the ticket purchase business normally on the 12306 website; Users with other identities need to confirm the correctness of the information filled in the 12306 website, or go to the station window or the sales point to check their identity information with the original documents.
4. In case of long names, uncommon words, traditional Chinese characters, etc. Can only be handled at the ticket window of the station. Registered users should also provide the last 4 digits of the mobile phone number or the first 3 digits of the registered email address, and common contacts should also provide the ID number filled in by registered users when registering. So, how long it takes depends. If the online verification only takes a few minutes, if the ID card needs to be processed at the window, it will take a long time. In short, the verification requires the user to wait patiently, and the ticket purchase will be more secure after the verification is successful. Although it is troublesome, at least the information security will not be leaked.
