How UPI works in an IPO application (ASBA 2.0 explained)

Why UPI was added to the IPO process

The original ASBA (Application Supported by Blocked Amount) system let retail investors apply for an IPO through their own bank, blocking the application money in place rather than remitting it to the issuer. Shares were allotted and the blocked amount debited on allotment day, with the unallotted portion released immediately. This was a significant improvement over the old cheque refund system, but it still required visiting a bank branch or logging into net banking and navigating ASBA forms.

SEBI introduced UPI as a second channel for retail investors applying through stock brokers and other non-bank intermediaries, making it possible to apply for an IPO entirely from a broker's app on a phone without touching a bank portal. The investor enters their UPI Virtual Payment Address (VPA) in the application, and the broker or registrar sends a mandate request to that UPI ID. The investor approves the mandate on their UPI app and the bank blocks the amount. Simple, fast, and entirely digital.

From a certain date, SEBI made the UPI channel mandatory for retail applications routed through registered brokers and RTAs for issues below a certain size, with the bank ASBA channel kept open for those preferring the older route. This means most retail investors today apply via UPI if they are going through a broker's app rather than directly through their bank.

What happens from application to allotment

Once you approve the UPI mandate, the bank places a lien on the application amount. The money stays in your account, continues to earn interest on a savings account, and is visible to you, but you cannot withdraw it or use it for UPI payments until the lien is lifted. The registrar aggregates all applications and runs the allotment process after the subscription window closes.

If you are allotted shares, the blocked amount equal to the allotment value is debited from your account on allotment day and credited to the issuer. The shares appear in your demat account on the scheduled credit date. If you are not allotted, the lien is fully released, the money is free again, and you never owe anything. If you are partially allotted fewer lots than you applied for, only the value of the allotted portion is debited and the rest is released. Throughout the process, because funds are blocked and not moved, the risk of the issuer disappearing with your money before allotment is eliminated.

Common issues and how to avoid them

The most frequent point of failure is the mandate expiring or being rejected. UPI mandates have a validity window, and if you do not approve the mandate within that window, your application is treated as if it was not placed. Always check your UPI app for the pending mandate request within the first few minutes of submitting the application, especially on heavily subscribed IPOs where the registrar sends thousands of mandates at once and UPI rails can be slow.

A second point of confusion is the per-application limit. The UPI payment channel for retail IPO applications is valid up to a defined per-application amount set by SEBI. For applications above that limit, the bank's ASBA route through netbanking or a bank branch remains the required channel. Check the current limit before applying so you are routing through the correct channel for your application size.
