When CCB handles credit cards, the validity period of ID cards is easy to make mistakes. You can look at the expiration date on the back of your ID card. If there is a specific time, do not choose long-term validity, choose non-long-term validity, and enter the expiration time. There are also address formats and fixed telephone formats that are prone to errors. Pay attention to the specific district/town/village, road name and house number when filling in.
