That is, when I booked the hotel, I promised to fill in the credit card number of ICBC. He said that the credit card number verification failed. Why?

Hello! Thank you for your interest in Ctrip.

If you use a credit card guarantee when booking a hotel, you will be prompted that the card number verification failed. In order to help you better, I suggest you confirm whether the card number is correct, or you can try to contact the credit card issuer for consultation. If you have any questions in the follow-up, you can follow Ctrip's micro-signal (ICRIP) to find us, click "Micro-service-Labor Service" between 9:00- 18:00, inform the specific matters and provide the order number, and someone will check it for you ~

There is good news from Bian Xiao again! As long as you pay attention to and bind Ctrip's micro-signal (ICRIP) and WeChat replies with the words "bound" or "associated", there will be intimate friends around you ~ It is convenient and fast to book with WeChat, and there are a series of rich functions such as "My exclusive-preferential activities" to surprise you who love to travel ~
