Hello, in fact, any email address can be used to apply for a bank card, as long as it is your own activated account, such as your own QQ email address. Just pay attention to the correct address format and follow the format of user name @ domain name. The user name is usually your digital account number, or English account number, or mobile phone number account number, but it should not be written in the format of website address, and should be separated by English @ symbol. Note that there can be no extra spaces before and after the @ symbol, and the separator in the domain name is also an English symbol, and it is below.
