Retrieving your forgotten UAN (Universal Account Number) is easy with your PAN card. Head to the EPFO member portal. Look for "Know Your UAN" and provide your registered mobile number and captcha code. An OTP (one-time password) will be sent to your phone for verification. Once verified, enter your name, date of birth, and PAN details. If your PAN is linked to your UAN, clicking "Show My UAN" will display your unique 12-digit number. Remember, this method relies on a linked PAN. If not linked, contact your employer for assistance.
