dear ramya
first you must clarify that, your friend got any new UAN number for his old PF number replacement. better you could check on it!now, if that particular person is having the EPFO on line then he can directly apply to the transfer by filling the form 13. if it is not you can ask the pf number by approaching the local PF office with enquiry.
other wise would you like to withdraw the PF amount then you can get the amount with interest as per table D withdrawal value based upon the no.of years employee contribution(if employee is having the amount 50000 in his PF account for 2 years he may get the amount of interest rate of 2.05 as per PF act) and that to this Table - D is applicable up to 9 years only after that he is eligible to pension plan this . but that is not suggestible to withdraw and it is crime also
thanks & regards
