First of all, if we are sure whether the credit card has been switched, if we are not sure whether it has been switched, we can apply for a temporary freeze or reduce the credit card limit to reduce the risk.
If it is confirmed that the credit card has been replaced, then we should call the customer service of the bank to which the credit card belongs at the first time to report the loss orally. Customer service will freeze the card. Reporting the loss orally in time can prevent the credit card from being stolen and ensure the security of your account. There is a time limit for reporting the loss orally. After the oral report of loss (basically 5 working days), the credit card holder needs to bring valid identity documents to the bank's business outlets to formally report the loss, and the bank will formally handle it. If the loss is officially reported, the bank will charge a certain loss reporting fee.
If the cardholder wants to continue to use the original credit card. You can reapply for a replacement after 7 days of reporting the loss. To reissue the card, the cardholder needs to go to the business outlet with valid identity documents. Although the new card issued by the bank to customers remains unchanged, the credit card number will change, which will protect the security and rights of customers' card information to the greatest extent. If you lose your unused credit card all the year round, the cardholder can choose to cancel it directly.
So after you find that your credit card has been accidentally dropped, you can report the loss and reissue it according to the above aspects, because it takes a certain fee to report the loss and reissue it. So I think it's better to take care of your credit card, and you can also avoid the trouble of reporting the loss and reissue it.
