PAN Query regarding IPO?

[Expert]

Please let me know is it mandatory to sign the pan card photocopy while applying for IPO? If not signed, can it be the basis for rejection ?

Can the sub broker give acknowldegment with his stamp on the acknowledgement copy? As normally acknowledgment is given by the syndicate member.

Thanks,
BC

Go and submit IPO online. Now a days almost all the DEMAT giving this opportunity.
