UPI for IPOs: How to Approve Mandate Requests

Rather than debiting your account immediately for the full application amount, an IPO application uses a UPI mandate to block the required funds in your account without transferring them, since the final allotment, and therefore the actual amount owed, is not known until the allotment process completes. This blocking mechanism protects you from paying for shares you may not ultimately receive.

1. Submit your IPO application through your broker's platform, entering your UPI ID at the appropriate step.

2. Open your UPI app within a reasonable window after submission, since a notification does not always arrive instantly.

3. Locate the mandate or collect request typically under a pending requests or approvals section.

4. Review the amount and payee details carefully, then approve with your UPI PIN to complete the block.

A mandate notification can be delayed due to backend processing time between your broker's platform and your UPI app, or it may simply be sitting unnoticed in a pending requests section rather than appearing as a prominent push notification. Checking your app manually, rather than waiting passively for a notification, is worth doing if you do not see it appear within a reasonable window after submitting your application.

This same mandate-approval mechanism is conceptually related to how a recurring credit card bill payment mandate works, though an IPO mandate is a one-time block rather than an ongoing recurring authorization.

Once share allotment is finalized, only the amount corresponding to shares actually allotted to you is debited from the blocked amount, with the remainder automatically released back to your account. If you receive no allotment at all, the full blocked amount is released without any portion being debited.

Approving the mandate too late, after the application window has closed, is a common and entirely avoidable mistake, so it is worth checking your UPI app soon after submitting your application rather than assuming you have unlimited time. Double-check the exact amount displayed in the mandate request matches your intended application amount before approving, since a mismatch can indicate an error worth investigating before confirming.

If approving the mandate itself fails or returns an error, check that your account has sufficient balance to support the block, confirm your UPI app and bank are both functioning normally, and retry within the application window if time permits. If the issue persists close to the deadline, contacting your broker's support promptly is worth doing rather than continuing to retry alone.

Before UPI-based applications became standard, ASBA applications typically required visiting your bank branch or using net banking directly, a comparatively slower process than approving a mandate from your phone within minutes of applying through your broker. UPI-based IPO applications have largely replaced this older workflow for retail investors precisely because of this speed and convenience advantage, though the underlying blocking principle behind both approaches remains essentially the same.
