How to know PF account number?
To find your Universal Account Number, either check your salary slip or visit EPFO member portal and go to ‘Know Your PAN’ option.
If you go to EPFO website to get your UAN, you will have to enter basic details like PF member ID, Aadhaar or PAN and registered mobile number. Once you validate with an OTP, your UAN will be displayed on the screen.
The best way to check is to check the salary slip anyway or ask your HR or payroll department. They can help you out.
