Why an IPO Application Gets Rejected

A rejected IPO application never reaches the allotment draw. The reasons it happens — unapproved UPI mandate, short balance, duplicate PAN, name mismatch, wrong category — and how to avoid each.

Two very different things get described as “my IPO application failed”. One is losing an oversubscribed draw, which is ordinary and says nothing about you or your application. The other is rejection — the application was disqualified before the draw was even run. This page is about the second, because unlike the first it has causes you can do something about.

Rejection is not the same as non-allotment

When the retail portion of an issue is oversubscribed, the registrar runs a draw for one-lot units. Most applicants do not get shares. That is the system working as designed, and it is covered in how IPO allotment works.

A rejected application is filtered out before that point, for a technical or eligibility reason. It had no chance regardless of how the draw went. The money comes back either way, so the two outcomes look identical from your bank statement — which is why people repeat the same mistake across several issues without realising it.

1. The UPI mandate was never approved

This is the most common cause by a wide margin. Submitting the bid in your broker's app does not block any money. It sends a mandate request to your UPI app, and you have to open that app and approve it. If you do not, the request expires — typically by 5 PM on the closing day, and often earlier at your broker's internal cut-off.

Approve the mandate immediately after bidding, then confirm the amount actually shows as blocked in your bank account. Do not treat the broker's “bid placed” confirmation as the end of the process.

2. Not enough clear balance when the block is attempted

The full bid value must be available as clear funds. A cheque or transfer that has not settled is not clear balance, and a block attempted against it fails.

Bids are blocked at the top of the price band even when you bid at cut-off, so the amount required is the higher figure. If the issue prices below the top of the band, the difference is released later — but it has to be there on the day.

3. More than one application on the same PAN

One PAN gets one application in a category. When the registrar finds duplicates it generally rejects all of them, so a second application does not double your chances — it can eliminate them.

4. PAN, bank and demat details that do not reconcile

• PAN mismatch. The PAN on the application must match the PAN on the demat account.
• Name mismatch. Differences between the name on the bank account and the name on the demat account — initials, a maiden name, a changed surname — can fail validation.
• Third-party funding. The blocked account must belong to the applicant. Applying with a spouse's or parent's account is rejected even when the money is genuinely available.
• Inactive or frozen demat account. A dormant account or lapsed KYC will fail at credit stage. Worth checking before an issue you care about, not during it.

5. The bid itself was invalid

Not in whole lots

Bids must be for the minimum lot or exact multiples of it. Arbitrary share counts are rejected.

A price below the final issue price

If you name a price rather than bidding at cut-off, and the issue is priced above your bid, your application is not considered. Retail investors can bid at cut-off specifically to avoid this, and there is rarely a reason not to — see how to apply for an IPO.

The wrong category for the size

A retail application is capped at ₹2 lakh. Bidding above that under the retail category, or bidding at cut-off as an HNI (which is not permitted), invalidates the application.

6. A UPI handle or bank that is not eligible

Not every bank and UPI app is on the approved list for IPO mandates. A handle that works fine for everyday payments may simply never deliver the mandate request. If a mandate does not arrive within a few minutes of bidding, that is usually the reason — switch to the net-banking ASBA route rather than resubmitting.

7. Applying too late on the closing day

The issue closes at 5 PM on the final day, but brokers set earlier internal cut-offs, and the mandate still has to be approved before that. Bidding in the last hour of the last day leaves no room for a mandate that does not arrive promptly. Apply on day one or two of the window.

How to tell which happened to you

The registrar's allotment page is the place to look. A valid application that lost the draw shows up with shares applied and zero allotted. A rejected application typically does not appear at all, or appears flagged as rejected. The various ways to check are set out in how to check IPO allotment status, and live results for current issues are on our allotment page.

Either way the blocked funds are released on T+2. If they are still blocked several working days later, raise it with the bank that placed the block — the block sits on the bank's side, not with the registrar or the company.
