1. Please confirm whether the bank card to be bound is within the range of card types that support binding (you can check the supported bank card types on the binding page).

2. Please make sure that this is your own account and the account status is normal.

3. Please check whether the card number, name, ID number, bank reserved mobile phone number, mobile phone verification code and other information are entered correctly.

If all the above are correct, it may be the bank's restrictions. I suggest you change your bank card and try binding again. Thank you for your cooperation.
