Why Do IPO Applications Get Rejected?

Every year thousands of IPO applications across India get rejected due to simple, entirely avoidable mistakes. A rejected application means you miss out on the allotment lottery entirely — even if you had a genuine chance of receiving shares. Understanding the most common rejection reasons and taking a few minutes to double-check your application before submission can make the difference between participation and disqualification.

Mistake 1 — Applying with Multiple Applications from the Same PAN

This is the single most common reason for IPO application rejection. SEBI strictly prohibits multiple applications from the same PAN in the same IPO. Whether you apply through two different brokers, two different bank accounts, or two different UPI IDs — if the PAN is the same, all applications from that PAN will be rejected outright. Each individual must apply only once per IPO using their unique PAN. To apply from multiple accounts legitimately, each account must belong to a different individual with a separate PAN.

Mistake 2 — Not Approving the UPI Mandate on Time

For UPI-based IPO applications, submitting the application through your broker is only the first step. You must also approve the payment mandate request that arrives on your UPI app — Google Pay, PhonePe, Paytm, or your bank's UPI app. If you do not approve this mandate before the deadline — typically 5:00 PM on the day of application — your application is treated as incomplete and rejected automatically. Always approve the UPI mandate immediately after submitting your IPO application.

Mistake 3 — Insufficient Bank Balance During the Subscription Period

When you apply for an IPO through ASBA or UPI, your application amount is blocked in your bank account. If your account balance drops below the blocked amount at any point during the subscription period — due to EMI payments, bill payments, or other transactions — your bank may reject the block and your IPO application will be invalidated. Always ensure your account has a comfortable buffer above the application amount throughout the entire subscription window.

Mistake 4 — Bidding Below the Cut-Off Price

When you bid at a specific price within the price band instead of selecting the cut-off price option, you risk rejection if the final issue price is set above your bid. For example, if you bid at ₹190 in an IPO with a band of ₹180 to ₹200 and the final cut-off is set at ₹200, your application is automatically rejected. Retail investors should always select the cut-off price option to ensure their application remains valid regardless of where the final price is discovered.

Mistake 5 — Incorrect Demat Account Number

Entering an incorrect demat account number or DP ID in your IPO application causes a mismatch between your application and your demat account. If allotment is processed and the shares cannot be credited to the correct account, the allotment may be reversed. Always double-check your 16-digit demat account number before submitting any IPO application — copy it directly from your demat statement rather than typing it from memory.

Mistake 6 — Applying After the Subscription Deadline

IPO subscriptions close at a specific time — usually 5:00 PM on the closing day. Applications submitted after this deadline are not accepted under any circumstances. For UPI applications, the mandate approval must also be completed before the deadline. Do not wait until the last few hours to apply — UPI networks and broker platforms can experience high traffic on IPO closing days, causing delays that may result in a missed window.

Mistake 7 — PAN Not Linked to Demat Account

Your PAN must be linked and verified with your demat account for your IPO application to be valid. If your PAN is not properly linked or if there is a mismatch between the PAN in your application and the PAN registered with your depository, your application will be rejected during the verification process. Check that your PAN, demat account, and bank account are all properly linked before applying for any IPO.

Mistake 8 — Applying in the Wrong Investor Category

Retail investors applying for shares worth more than ₹2 lakhs are automatically reclassified into the HNI category, which has different allotment rules and no lottery system. If your intention was to participate in the retail lottery for a better allotment chance, ensure your total application value — lot size multiplied by number of lots multiplied by cap price — does not exceed ₹2 lakhs. Exceeding this limit removes you from the retail category entirely.

Conclusion

Most IPO application rejections are completely preventable with a few minutes of careful verification before you submit. Always apply with the correct PAN, bid at cut-off price, approve your UPI mandate immediately, maintain sufficient bank balance, and apply only once per IPO per PAN.
