2) Telephone inquiry: dial the credit card service hotline of the issuing bank with the reserved mobile phone number, and connect to the manual customer service according to the voice prompt, and ask the customer service to inquire the security code. Customer service may help you check after verifying your identity.
However, some customer services will not help the inquiry. After all, security codes are not like passwords. If you forget, you can set it yourself with the help of customer service. If it is discovered by customer service, it will be considered as a leak. Therefore, the safest way is to report the loss of the credit card and reissue a new one. After the new card arrives, the validity period and security code will change. Finally, I would like to remind you that there is generally a charge for reporting the loss of credit cards. The cost is around 50 yuan, depending on the bank and card type.
Credit card security code refers to the three digits printed on the back of the card, which can be regarded as the identity card of the credit card. It is an important payment voucher for credit card online payment and telephone remittance, and shall not be disclosed to others.
After all, many foreign websites can complete the transaction as long as they know the credit card account number and security code, and even some merchants who sign contracts with banks can complete the telephone transfer only with the security code. Therefore, once the credit card security code is leaked, it is easy to cause the credit card to be stolen.
As long as the applied credit card is successfully issued, the interval between the issuance of the next credit card does not need to be too long, especially if you apply for a credit card from another bank, or even apply together. However, credit cards should not be handled too frequently and the number of cards should not be too large. It is most suitable for one person to have about three names.
If the credit card application is rejected, it is best to apply for a second card at least three months apart, and the longer the interval, the better. Before re-applying, you should find out the reasons for refusing the card, and then re-apply after perfecting it. In particular, if the credit is rejected, don't blindly apply for a card, and do it after at least two years of credit investigation.
