The method of proof of settlement is as follows:

1. Call the customer service of the issuing bank and explain the purpose of the credit card balance certificate to the customer service. After the customer service inquires about your situation, if it meets the conditions for issuing cards, it will issue a balance certificate and send it to your designated receiving address by express delivery.

2. Bring my ID card and credit card to the counter of the issuing bank's business outlets.

It is necessary to pay off all the debts of the credit card when issuing the settlement certificate, and the personal credit is good, and there is no malicious overdue behavior for many times. If the cardholder has committed multiple malicious overdue behaviors, the bank will refuse to issue relevant settlement certificates.
