What is an IPO Registrar & What Do They Do?

An IPO Registrar is an independent SEBI-registered corporate body appointed by the issuing company. The registrar is solely responsible for collecting bid data from stock exchanges (BSE & NSE), eliminating duplicate or invalid bids, supervising the computerized allotment draw according to SEBI allocation formulas, dispatching shares to demat accounts, and notifying banks to unblock UPI mandates.
