Why is the IPO allotment status not available on the RTA’s portal?

The IPO allotment status may not be available on the RTA’s portal for one or more of the following reasons.
1) You may not have received an allotment in an oversubscribed issue, as non-allotted applications may not always appear.
2) Application errors such as incorrect PAN, Demat ID, UPI, or bank details, or a failed UPI mandate due to insufficient funds, can also lead to rejection.
3) In some cases, the RTA may still be processing applications or experiencing a temporary technical delay on the portal.
