No, changing your PAN number (by issuing a new PAN card) will not cause your CIBIL score to disappear. The CIBIL score is a reflection of your credit history and is linked to your credit report, which is maintained by the credit bureaus.

The credit report contains information on your credit accounts, such as credit cards, personal loans, home loans, and other types of credit. This information is used to calculate your CIBIL score, which is a three-digit number that indicates your creditworthiness.

If you change your PAN number, your credit history and credit report will still be maintained by the credit bureaus, and your CIBIL score will still reflect your credit history. The credit bureaus will update your credit report with the new PAN number, and your credit history will continue to be reflected in your credit report and CIBIL score.

However, if there are any errors or inaccuracies in your credit report, it’s important to get them corrected as soon as possible, as they can impact your CIBIL score and credit history. To check your CIBIL score and credit report, you can request a copy of your credit report from the credit bureaus, either online or by submitting a request in writing along with the required information and fees.
