Answer: Credit information is not displayed after the credit card is changed because the basic information of the credit card is usually associated with the card number in the credit report. Changing a credit card is generally just changing a card, and the card number and the account information associated with it have not changed substantially. Therefore, the change of the credit card itself will not cause the information in the credit report to change or update.

The credit report mainly includes your credit card account, loan account, repayment record, credit limit, credit usage and other information, which is generated and updated according to your account activity and repayment record. If there is no new activity in your credit card account or the repayment record has not changed, there is no need to update the corresponding credit report.

It should be noted that if your credit card account changes at the same time, such as changing the credit limit and account type, or closing the original account and opening a new account, these situations may lead to the update of information in the credit report. However, in general, it is rare to change the credit report just because of changing the credit card.

To sum up, credit card replacement usually does not directly lead to changes in the credit report, unless it is accompanied by other important changes related to credit accounts. In order to ensure the accuracy of your credit report, it is recommended to check your credit report regularly and correct any wrong information in time.
