Monica,
To answer your question on Provident Fund for BPO’s .
The PF department has a website where all industries that need to enrol in the PF scheme is listed.
IT/ITES companies , when I last looked , were not in the list of 180 odd companies so classified..
However it is advisable that you look at the site http://www.epfindia.com and write a formal letter to the EPF organisation seking clarification.
