My question is possibility to get PF settlement? as per PF Act.. So kindly give me an correct guideline.

Dear Mr. John C,
May I Know when it was happen. I think before three or four months PF make it mandatory to enter AADHAR card number while registering new employees. So there will not be a chance to create a new UAN number if your friend join within last three to four months.
On the other hand if your friend joined before that, he cannot withdraw the amount unless contribution is remitting to a UAN number mapped to the AADHAR card.
