Making multiple applications is not only wrong but it will also lead to rejection of application. Multiple applications are seen by the regulator as a fraudulent method of cornering shares by a handful of investors in the retail quota. SEBI is very strict about the misuse of the retail quota, so don’t do such things. To cut a long story short, the answer is one can only make a single application in an IPO in his/her name. More than one application from a single bank account are possible as long as applications are filed under different PANs. If more than one application are detected under a PAN in an IPO, all applications are liable to be rejected. The regulator also reserves the right to take action against such cases.
