Individuals in India can protect themselves from PAN-based loan fraud by regularly checking their credit reports. Unauthorized loans taken using one's PAN can lead to significant financial and credit score damage. Accessing reports from bureaus like CIBIL, Experian, Equifax, or CRIF High Mark, or using fintech apps, allows for the identification of unknown loans. Early detection through these methods is crucial for preventing long-term financial distress and legal issues.
