Do you want to ask the question "Why can't eBay bind CCB credit card?" The reasons for this situation are that the credit card is not activated or has expired, the credit card information entered is incorrect, the credit card does not support payment on eBay, and eBay system failure.

1. The credit card is not activated or has expired. Please confirm that the CCB credit card has been activated and is within the validity period.

2. The entered credit card information is incorrect. Please check that the credit card number, expiration date and security code you entered are correct.

3. Credit cards do not support payment on eBay. Please check whether the credit card supports international payments and online payments.

4. eBay system failure. Please confirm whether the eBay system is running normally and whether other users have reported similar problems.
