UPI vs ASBA vs Broker Platforms: The Best Way to Apply for IPOs in India Today
If you are deciding the best way to apply for an IPO in India, you have probably seen three terms thrown around as if they are rival options: UPI, ASBA, and broker platforms. They are not really three competing choices. Once you understand how they fit together, picking the right route for your own application takes about a minute.
Here is the short version. ASBA is the underlying system that blocks your money instead of debiting it. UPI is one way to authorise that block. A broker platform is simply where you fill the form. This guide breaks down the two real paths a retail investor can take, what changes between them, and which one suits you.
First, clear up the biggest misconception
ASBA stands for Application Supported by Blocked Amount. Since SEBI made it compulsory, every public issue in India, whether an IPO, FPO, or rights issue, must use ASBA as the only mode of payment. When you apply, your application money is not pulled out of your account. Your bank simply blocks it. The amount keeps sitting in your account, often still earning interest, and it is debited only if shares are allotted to you. If you get no allotment, the block is released.
So ASBA is not an option you choose against UPI. ASBA always happens. The real question is how you authorise that block. You have two ways to do it:
- Let your bank block the money directly through its net banking portal.
- Let a UPI mandate authorise the block when you apply through a broker.
That is the genuine choice. Everything else is detail.
Path 1: Bank net banking (ASBA without UPI)
In this route you log into your bank's net banking, find the IPO or ASBA section, and submit the bid there. The bank you hold an account with acts as the intermediary and blocks the funds against your application. There is no UPI mandate involved at all.
This path works for everyone, including amounts above the UPI ceiling. It is the standard route for High Net-worth Individuals and large applications, because UPI has a size limit that the net banking route does not.
The catch is availability and interface. Not every bank offers a clean ASBA flow in net banking, and the screens are often clunky compared with a modern broker app. If your bank supports it and you are comfortable there, it is reliable.
Path 2: Broker platform with a UPI mandate
This is how most retail investors apply today. You open your broker's app or website, fill the IPO bid, enter your UPI ID, and submit. A mandate request then lands in your UPI app (Google Pay, PhonePe, BHIM, Paytm, or your bank UPI app). You approve it once, and the amount is blocked. You do not pay anything upfront beyond approving the block.
A few rules govern this route:
- UPI for IPO applications is available only to retail individual investors. Qualified Institutional Buyers and HNIs cannot use it and must apply through the existing net banking or syndicate process.
- The UPI route is capped at ₹5 lakh per application. If your bid is larger, you cannot use UPI and must switch to bank net banking.
- The UPI ID must be linked to a bank account in the name of the same person whose PAN is tied to the demat account. Third-party UPI IDs get the application rejected.
- The mandate has to be approved before 5:00 PM on the closing day of the issue. Approve it the moment it arrives, not at the last minute.
The broker platform itself is just the front end here. Zerodha, Groww, Upstox, Angel One, and others all sit on top of the same UPI-ASBA plumbing. We walk through one broker flow step by step in our guide on how to apply for an IPO via Zerodha.
A direct comparison
| Feature | Bank net banking (ASBA) | Broker platform (UPI) |
|---|---|---|
| Who can use it | All investor categories | Retail individual investors only |
| Application limit | No UPI cap; suits large bids | Up to ₹5 lakh per application |
| Where you apply | Bank's net banking portal | Broker app or website |
| How funds are blocked | Bank blocks directly | UPI mandate authorises the block |
| Approval step | Done inside net banking | Approve mandate in your UPI app by 5 PM on close day |
| Best for | HNIs, large amounts, net-banking users | Most retail investors, quick mobile applications |
Notice that both columns are ASBA. The money is blocked, not debited, either way.
Which one should you actually use?
For a typical retail investor applying within the ₹2 lakh retail window, the broker plus UPI route is usually the simplest. The form is cleaner, allotment and refund tracking sit in the same app, and approving a mandate takes seconds.
Choose bank net banking if any of these apply to you: your application is above ₹5 lakh, you are applying in the HNI category, your UPI app keeps failing to fetch the mandate, or you simply trust your bank's interface more. The net banking route has no UPI size ceiling and does not depend on a mandate reaching your phone in time.
Whichever path you pick, the things that get applications rejected are the same: a wrong or third-party UPI ID, a PAN mismatch, more than one application per PAN, or missing the mandate approval cut-off. Apply early in the window so a failed mandate leaves you time to retry.
After you apply: blocking, allotment, and unblocking
Once submitted, your money stays blocked through the bidding and allotment process. After the issue closes, the registrar finalises who gets shares. If you are allotted, the blocked amount is debited and the shares hit your demat account. If you are not allotted, the block is lifted and the funds are freed, usually within a day or two of the allotment being finalised.
You can check where an application stands using the registrar's allotment status page once the basis of allotment is published. For the wider picture of how shares get divided when an issue is oversubscribed, see the IPO allotment process explained. It also helps to know which category you fall in, since the limits differ; our breakdown of QIB, NII and retail investor categories covers that.

Frequently asked questions
Is ASBA different from applying through UPI? Not really. ASBA is the system that blocks your money instead of debiting it, and it is mandatory for every IPO. UPI is just one way to authorise that block when you apply through a broker. Even a UPI application is an ASBA application underneath.
What is the maximum IPO amount I can apply for using UPI? ₹5 lakh per application. The UPI route is open only to retail individual investors. If your bid is larger, or you are applying as an HNI, you must use the bank net banking ASBA route instead.
Can I apply for the same IPO through two different brokers? No. Only one application per PAN is allowed across the entire issue. Submitting more than one under the same PAN, even through different brokers or banks, gets all of them rejected.
Why was my IPO UPI mandate rejected? The usual reasons are a UPI ID linked to someone else's bank account, a PAN that does not match the demat account, or approving the mandate after the 5:00 PM cut-off on closing day. The UPI ID must belong to the same person who owns the demat account.
Does my money earn interest while it is blocked? Yes. Under ASBA the amount stays in your bank account and is only blocked, so it continues to earn interest as usual until shares are allotted and the money is actually debited.
