Getting rejected after successfully applying is frustrating — and avoidable. Here are the most common reasons IPO applications are rejected and exactly how to prevent each one.
Why Do IPO Applications Get Rejected?
Every year, thousands of valid IPO applications are rejected due to simple, preventable errors. A rejection means your UPI block is released and you miss the allotment lottery entirely — even if the IPO lists at a premium. Here are the most common causes.
1. UPI Mandate Not Approved in Time
This is the single biggest reason for IPO rejections. After submitting your application, you receive a UPI collect request. You must approve this within the time limit — typically 30 minutes to a few hours (varies by exchange and broker). If you miss it, your application is cancelled.
- Set an alarm after applying — check your UPI app immediately
- Ensure your UPI app notifications are turned on
- Never apply and immediately go offline or into an area with poor network
2. Multiple Applications from the Same PAN
Each PAN can have only one application per IPO. If you apply from multiple demat accounts linked to the same PAN, all applications are rejected — not just the duplicates. This is a firm SEBI rule with no exceptions.
3. Bank Account Not Linked or Insufficient Balance
Your UPI ID must be linked to a bank account that has at least the application amount as free balance. Even though ASBA only blocks — not debits — the funds, the bank rejects the UPI mandate if the balance appears insufficient at the time of processing.
4. Name Mismatch Between Demat and Bank Account
The name on your demat account must match the name on your bank account and PAN card. Discrepancies in spelling or initials can cause rejections during the exchange validation process.
5. Applying at Wrong Price
In a fixed-price IPO, applying below the issue price means automatic rejection. In a book-built IPO, if you apply below the final cut-off price, your application is rejected. Always select "Cut-off Price" when applying — this ensures your bid is valid at whatever final price SEBI approves within the band.
6. Incomplete or Incorrect Details
Errors in DP ID, Client ID, PAN number, or lot quantity (below minimum) will cause rejections at the registrar level. Triple-check your demat account details before submitting.
