UPI Mandate in IPO: How the Block, Debit and Unblock Actually Work

You tap “apply” on an IPO in your broker app, and a minute later your UPI app pings you with a request to approve. That request is the UPI mandate in IPO bidding, and it is the step where most first-time applicants either get it right or quietly lose their bid. Nothing is debited at that point. The money is only blocked. What happens to it next depends on allotment.

This guide walks through what the mandate is, who has to use it, the limit that applies, and how the block turns into a debit or a release. We also run a worked example with made-up numbers so you can see the arithmetic, and close with the mistakes we see people make most often.

What a UPI mandate in IPO applications actually is

Indian IPOs run on ASBA, short for Application Supported by Blocked Amount. Under ASBA your bank does not send money to the issuer when you apply. It simply sets aside, or blocks, the bid amount in your own account. If you get shares, the blocked amount (or part of it) is debited. If you don’t, the block is lifted. We have covered the wider ASBA route in our guide to the ASBA IPO application process.

UPI is the payment rail that lets this block happen from your phone. According to SEBI’s April 5, 2022 circular, the regulator introduced UPI as an additional payment mechanism with ASBA for retail individual investors through a circular dated November 1, 2018, and made it mandatory from July 1, 2019 for retail applications submitted through intermediaries.

The “mandate” is the block request itself. You authorise it once, with your UPI PIN, and that single authorisation covers both the block now and the debit later if you get an allotment.

Who has to use UPI, and the Rs 5 lakh limit

The limit is the bit people get wrong most often, so let’s be precise about it.

The same SEBI circular records that NPCI (National Payments Corporation of India), through a circular dated December 9, 2021, raised the per-transaction UPI limit for UPI-based ASBA applications in IPOs from Rs 2 lakh to Rs 5 lakh. SEBI then decided that all individual investors applying in public issues where the application amount is up to Rs 5 lakh shall use UPI and shall give their UPI ID in the bid-cum-application form. That rule applies to public issues opening on or after May 1, 2022.

SEBI’s circular also notes that before it moved, NPCI had confirmed that as on March 30, 2022, more than 80% of SCSBs, sponsor banks and UPI apps had made the system changes. That 80% figure is a share of those intermediaries, not of investors. The Economic Times reported the change the same day.

So, in plain terms:

• If you are an individual and your application amount is Rs 5 lakh or less, UPI is the route, with your UPI ID on the form.
• The Rs 5 lakh cap is per transaction on UPI. SEBI’s investor education page puts it as “Rs.5 Lakhs per transaction on UPI”.
• Above that amount, UPI is not the payment route, and you would bid through net banking ASBA with your bank instead.

Your category inside the IPO is a separate question. The retail individual investor portion has its own cap per application, which we break down in our explainer on the retail individual investor quota. Don’t mix the two up. One is about which bucket your bid sits in. The other is about which payment rail can carry it.

How the mandate flows, step by step

SEBI’s investor page on applying in IPOs through ASBA splits the process into three stages. Here is what each one means when you are the one holding the phone.

1. You bid and give your UPI ID

You fill in the bid details along with your UPI ID. The application goes through an intermediary, which SEBI lists as a syndicate member, a registered stock broker, a registrar and share transfer agent, or a depository participant. In practice, for most of us, that intermediary is our broker’s app.

The intermediary uploads the bid and your UPI ID on the stock exchange bidding platform. The exchange then shares those details electronically with the sponsor bank appointed by the issuer.

2. The sponsor bank asks you to block funds

The sponsor bank sends a request to your UPI app asking you to authorise a block equal to your application amount, and the later debit if you get shares. You approve with your UPI PIN. Once the request is validated, the money is blocked in your account and you are informed.

This is the moment that decides whether your bid counts. A bid uploaded by the broker but never approved in the UPI app is not a funded bid. Our list of common IPO application rejection reasons covers what tends to go wrong around here.

3. Allotment decides debit or release

After allocation, the debit happens for shares you were allotted, and any excess is unblocked. SEBI’s page is explicit that this debit relies on the authorisation you already gave with your UPI PIN while blocking. You won’t get a second approval request for the debit.

The PIN you enter on bid day does two jobs at once. It blocks the money now, and it pre-approves the debit later if shares come your way.

A worked example, with hypothetical numbers

The figures below are invented for illustration. They are not from any real IPO.

Say an IPO has a price band whose upper end is Rs 250, and the lot size is 60 shares. One lot at the top of the band costs 60 x 250 = Rs 15,000.

You decide to bid for 4 lots at the cut-off price. Your application amount is 4 x 15,000 = Rs 60,000. That is well under Rs 5 lakh, so as an individual you use UPI and enter your UPI ID.

Here is how the money moves:

• Bid day: your broker uploads the bid. A request for Rs 60,000 lands in your UPI app. You approve with your PIN, and Rs 60,000 is blocked. Your balance still shows the money, but you can’t spend that Rs 60,000.
• Allotment, scenario A: the issue is heavily subscribed and you get 1 lot. Rs 15,000 is debited for 60 shares and the remaining Rs 45,000 is unblocked.
• Allotment, scenario B: you get nothing. The whole Rs 60,000 is unblocked.

Now push the numbers the other way. Suppose you want to bid Rs 6 lakh in the same IPO. That is above the Rs 5 lakh UPI per-transaction limit, so this bid can’t ride on UPI. You would apply through ASBA via your bank’s net banking. A bid that size may also sit in a different investor category, so read our guide to IPO basis of allotment before you place it.

The checks SEBI asks you to run before you bid

SEBI’s investor page lists a few points to remember. We would treat them as a pre-flight checklist:

• Your bank must be on the list. Create your UPI ID with a bank named in SEBI’s list of Self-Certified Syndicate Banks (SCSBs) eligible to act as an issuer bank.
• Your app and UPI handle must be on the list. Use only the mobile apps and UPI handles named in SEBI’s list of apps for UPI in public issues.
• Submit through the right channel. Applications with UPI as the payment mechanism go only to a syndicate member, registered broker, RTA or depository participant.
• Use your own account. A third-party UPI ID, or a third-party bank account, will not be considered for allocation.

That last point catches families out every IPO season. If the demat account is in your name, the UPI ID and the bank account behind it need to be yours too. Using a spouse’s or parent’s UPI handle for your application is exactly the case SEBI says won’t get an allotment.

Mistakes we see with the UPI mandate in IPO bids

None of these are exotic. They are just easy to slip into on a busy day.

Not approving the request at all

People bid in the broker app, close it, and assume they are done. The bid isn’t funded until you approve the block in the UPI app. Check the app’s pending requests right after you bid, and don’t wait until the last evening of the issue.

Bidding from an account without enough balance

The block needs the full application amount sitting in the account linked to that UPI ID. If you bid Rs 60,000 and the account has Rs 40,000, the block can’t go through.

Mixing up the UPI limit and the retail cap

The Rs 5 lakh figure is the UPI per-transaction limit for these applications. Your investor category is decided by different rules. Read both before deciding how big a bid to put in.

Assuming money left the account

A blocked amount hasn’t been paid to anyone. It is still in your account. It is simply unavailable until allotment settles things. When you check your IPO allotment status, also check the bank account. The two should tell the same story.

Blocked is not spent. Until allotment, that money is still yours. You just can’t use it.

Why the mandate route is the default for small investors

UPI pulls the whole process onto the same phone you already use for groceries and bills. The 2022 change mattered because it lifted the ceiling from Rs 2 lakh to Rs 5 lakh, so more individual applications could use the phone route instead of being pushed back to net banking.

There is also a cleaner audit trail. The exchange, the sponsor bank and your UPI app all see the same bid and the same amount. When allotment is done, the debit and the release follow from the single authorisation you gave. If something looks off, there are only a few places to check: the broker’s order status, the UPI app’s mandate history, and your bank statement.

Quick recap before your next IPO bid

• As an individual applying for up to Rs 5 lakh, use UPI and put your UPI ID in the application (SEBI circular of April 5, 2022, for issues opening on or after May 1, 2022).
• Approve the block in your UPI app with your PIN. That one approval also covers the later debit.
• Use your own bank account and a SEBI-listed bank, app and UPI handle.
• On allotment, you pay only for the shares you get, and the rest of the block is released.
