When your credit card is overdue, the bank asks if you want to say your ID number.

No, you have personal information in a regular bank.

If the credit card is overdue for more than 30 days and exceeds one billing cycle, the bank will collect it. First, short message collection. Mainly for the cardholder's early and overdue repayment behavior, usually 7 to 15 days overdue. SMS mainly plays the role of reminder. Second, telephone collection. Call to remind repayment mainly for overdue behaviors that are more than 30 days and more than one billing cycle. Third, door-to-door collection. Mainly overdue for more than 90 days, the bank will arrange the collection staff to collect the repayment at the cardholder's residence or work address. Fourth, the court sued. Mainly more than half a year overdue, the bank will apply to the court to sue the cardholder for repayment. Fifth, outsourcing collection. Mainly for overdue 1 year or more, the bank packages and discounts overdue funds to the outsourcing collection company, which is responsible for overdue debt collection.

Personal information of citizens involves privacy. Just repay the credit card in time if it is overdue. In addition, I suggest you check whether you are a bank employee first, and be careful of online fraud.
