Why IPO applications get rejected (and how to avoid it)

Updated 26 October 2026 · 4 min read

Every big IPO leaves thousands of investors who are sure they applied, but find "application rejected" or "not found" when allotment comes out. Usually the money was never debited, so the only loss is the missed chance — but it is frustrating, and almost always avoidable.

An application can fail at three stages: it never becomes a valid bid (most often a UPI mandate that was not approved), it is rejected as technically invalid when the registrar checks it, or it is valid but simply does not win the allotment lottery. This guide covers the first two, which are the ones you can control.

1. The UPI mandate was not approved in time

This is by far the most common reason. Placing the bid in your broker's app is only half the job: the bid becomes valid only when you approve the mandate request in your UPI app. If the mandate arrives late, is ignored, expires, or is approved after the 5 pm deadline on the closing day, the bid does not count.

• Approve the mandate as soon as it arrives — look under "Mandates" or "Autopay" in your UPI app if you did not get a notification.
• Apply on day one or two. On the last afternoon of a popular IPO, mandates can take hours to arrive.
• If no mandate arrives within a few hours, cancel the bid in your broker app and apply again, or use net-banking ASBA instead.

2. More than one application from the same PAN

The exchange and registrar match applications by PAN. If the same PAN appears in two bids in the same category — even from two different brokers, or one through UPI and one through ASBA — they are treated as multiple applications and rejected. A family can apply from each member's own PAN; a single person cannot apply twice in the retail category.

3. Bank account, UPI ID and demat account belong to different people

The money must come from the applicant's own bank account. Bids paid from a spouse's or parent's UPI ID are a frequent rejection reason. Some UPI apps even let you use a third-party UPI handle; the registrar will still reject the bid if the account holder does not match the PAN on the application.

4. Bidding below the final issue price

If you enter a price instead of choosing cut-off, and the final price is fixed at the top of the band (as it is in most popular IPOs), a lower bid is not considered for allotment. Retail investors should almost always tick "cut-off price".

5. Wrong category or application size

• A retail bid above ₹2 lakh is not a valid retail bid.
• Small HNI (sNII) bids must be above ₹2 lakh and up to ₹10 lakh; big HNI (bNII) bids must be above ₹10 lakh.
• Employee or shareholder quota bids from people who are not eligible on the record date are rejected.
• For SME IPOs the minimum application is larger (two lots), and a bid below it is invalid.

6. PAN, name or demat details do not match

The registrar checks that the PAN, the demat account (DP ID and client ID) and the name all match the depository records. An inactive or frozen demat account, a PAN not linked to Aadhaar (an "inoperative" PAN), or a demat account in a different name leads to rejection. If you opened your demat account recently, make sure KYC is complete and the account is active before applying.

7. Insufficient balance when the amount is blocked

When you approve the mandate, the bank blocks the full application amount. If the balance is short at that moment, the block fails and so does the bid. Keep the money in the account until the issue closes; if you move it out after the block, the block itself stays in place.

Rejected vs not allotted: how to tell

Checklist before you hit "Apply"

1. Demat account active and KYC complete; PAN linked to Aadhaar.
2. Bank account and UPI ID in the same name as the demat account.
3. Only one bid per PAN in each category.
4. Retail: cut-off price ticked, total under ₹2 lakh.
5. Enough balance for the full amount.
6. Mandate approved in the UPI app — and checked under "Mandates" that it shows as approved.
