Dear Sunnidec311,
First of all, plz. let us know "Where you are sending your EPF W/d Form", "who is asking you for Id Proof or Re-leaving letter" and "Are you currently working and you are covered under EPF"..?
Second thing I would like to tell that, Id Proof / Re-leaving Letter is never required for the EPF W/d process.
If you are currently covered under EPF then you must transfer that amount to your currently EPF A/c. For that, you have to submit Form-13 (can be also submitted online through <link no longer exists - removed> ) and it can be attested from the current employer.
If you are currently not working than first of all fill Form- 10C & 19. Attach a Canceled Bank Cheque, properly signed / copy of 1st page of Bank Passbook duly self attested.
After this, just go to your banker and get the signature verified from the Bank Manager. After that, keep its a copy with you and send the original attested form to Concern EPF Office directly through Speed Post / Registered Post.
Your problem will be get solved. Hope it will help you. Be Happy..
