The final repayment date can be calculated according to the billing date, which is generally the 25th day after the billing date. If you don't remember the billing date and repayment date, you can check the following channels:

1. Customer service telephone inquiry: Credit card holders can dial 95588, provide ID number and card number, and inquire about the billing date and repayment date.

2. Counter training: Credit card holders can check the bill date and repayment date at any ICBC counter with their ID cards and credit cards.

3. Online banking inquiry: log in to ICBC's personal online banking and select Credit Card Service-Statement and Settlement-Statement Inquiry-Inquiry to see the due repayment date.
