Can someone apply through more than one application in IPO with the same name?

One person cannot apply for multiple IPO applications at once. This is a rule. If with the same name you submit more than one applications to an IPO , same demat account, or same PAN number, your entire application will be disqualified/rejected.

You can place multiple orders if you apply for each family member. However, all family members eligible for demat accounts and PAN numbers should be able to apply.
