A Permanent Account Number (PAN) Card e-PAN is usually delivered as a password-protected PDF for security. To open the file, you must enter a specific PAN card password format, which is typically a combination of your date of birth (DDMMYYYY). For example, if your birth date is 15 August 1990, the password will be 15081990. This security feature is implemented by the Income Tax Department of India to protect your personal details. Understanding the correct password format helps you quickly access and download your e-PAN Card without errors when you receive it via email or from official portals.
