UPI 2.0 mandate explained

This article is a focused explainer on the UPI 2.0 mandate as it functions in the context of an IPO (Initial Public Offering) application in India. For the full encyclopedic treatment of the mandate construct across all use cases, see UPI mandate . For step-by-step instructions on approving a mandate in a UPI app, see How to approve a UPI mandate for an IPO application .

What is a UPI 2.0 mandate?

A UPI 2.0 mandate is a future-dated, pre-authorised payment instruction introduced in UPI version 2.0, released by NPCI in August 2018. In the IPO context, it is a one-time block mandate: the investor pre-authorises a debit of up to the bid amount from their bank account on the date of mandate creation, but no money leaves the account immediately. Instead, the bank places a lien (block) on the funds. The actual debit occurs only if and when the investor is allotted shares.

The mechanism mirrors the older ASBA (Application Supported by Blocked Amount) process used by self-certified syndicate banks (SCSBs) , but replaces the bank’s direct lien instruction with a UPI-based authentication flow that any investor can complete from a mobile phone.

Why was the mandate construct needed for IPOs?

Under SEBI’s ASBA design, the investor’s funds must be blocked (not transferred) at the time of application. A simple UPI collect request, where the payee pulls funds from the payer immediately, would not serve this purpose, because:

• It would debit the investor immediately, regardless of allotment outcome.
• A refund on non-allotment would be operationally complex and would remove interest income from the investor during the application period.
• It would not preserve the investor’s account balance for other purposes during the allotment window.

The mandate construct solves this: the investor’s bank places a lien equivalent to the bid amount, the investor’s book balance is unchanged (and continues to earn interest), and the debit is executed precisely and only on allotment.

How it works: step by step

Step 1: Bid submission

The investor submits an IPO bid through a UPI-enabled broker app, stock exchange portal, or RTA investor platform. The bid specifies the lot size, quantity, and price (within the price band). The investor provides their UPI VPA (Virtual Payment Address) rather than bank account details.

Step 2: Mandate creation by sponsor bank

The exchange forwards the bid to the sponsor bank, the bank engaged by the IPO issuer to collect UPI ASBA applications for the issue. The sponsor bank generates a UPI one-time block mandate request for the investor’s bid amount (or the maximum bid value, if multiple bids are placed at different prices) and sends it to NPCI.

Step 3: Routing to PSP bank

NPCI resolves the investor’s VPA to the PSP bank , the bank behind the VPA handle. NPCI routes the mandate request to the PSP bank, which forwards a push notification to the investor’s linked UPI app.

Step 4: Investor authorisation

The investor opens their UPI app, navigates to pending requests, reviews the mandate details:

• Issuer name (should match the IPO company name).
• Block amount (should match the bid value).
• Validity end date (typically listing date plus one or two working days).
• Beneficiary (the sponsor bank).

The investor enters their UPI PIN. This authenticates the mandate without triggering any debit.

Step 5: Lien placement

On successful PIN entry, the PSP bank confirms the mandate to NPCI and instructs the investor’s account-holding bank to place a lien on the bid amount. The investor’s bank account balance available for other transactions decreases by the blocked amount. The book balance and interest accrual are unaffected, the investor earns interest on the blocked funds throughout the allotment window.

Step 6: Bid confirmation

The sponsor bank notifies the exchange that the mandate is authorised. The exchange updates the bid status from Mandate Pending to Mandate Accepted. The bid is now a valid application in the book-building process. The broker confirms the mandate acceptance to the investor, typically via push notification and email.

Step 7: Allotment and execution (or lapse)

After the issue closes and allotment is determined by the registrar and transfer agent (RTA):

• Allotted investors: The RTA instructs the clearing corporation, which instructs the sponsor bank to execute the mandate for the allotted value (not necessarily the full bid amount, partial allotments are common). The PSP bank triggers the debit from the investor’s account; the clearing corporation transfers the funds to the issuer’s designated account.
• Unallotted or partially allotted investors: The lien on the unallotted portion is released by the PSP bank. No debit is made. The full (or residual) blocked amount is restored to freely available balance immediately.

The 5 PM IST cutoff

SEBI regulations require that UPI mandates for IPO applications be authorised by 5 PM IST on the bid closing day. The mandate is only transmitted to the exchange as a valid bid after authorisation. If the investor submits a bid through a broker after 5 PM IST on bid closing day, or submits before 5 PM but does not authorise the mandate before 5 PM, the bid is not registered with the registrar and is automatically rejected.

This cutoff is absolute. The UPI infrastructure, the exchange system, and the NPCI switch all enforce it at the technical level. Investors who submit bids in the final minutes of the bid window must authorise the mandate immediately.

What happens to the blocked balance

The lien placed under a UPI ASBA mandate has the following properties:

• Visible balance impact: The investor’s bank account will typically show a reduction in available balance or lien balance equal to the blocked amount. The actual account balance (book balance) and interest balance are unchanged.
• Interest: The investor earns full interest on the blocked funds at the account’s prevailing interest rate. This is a regulatory requirement under SEBI’s ASBA design.
• Other debits: Ordinary debits (UPI transfers, card payments, ATM withdrawals) against the account are allowed up to the available (unlocked) balance. If the investor attempts to debit more than the unlocked balance, the transaction will fail, the lien protects the blocked funds from inadvertent exhaustion.
• Mandate revocation: The investor can revoke the mandate through their UPI app at any time before bid close, which constitutes a bid withdrawal. After the bid closing time, revocation is not possible until allotment instructions are completed.

Common failure scenarios

Relationship to the broader ASBA framework

The UPI mandate for IPO applications is the UPI-native implementation of the broader ASBA framework. The outcome for the investor is identical to bank ASBA via an SCSB : funds are blocked, not transferred; interest accrues; only the allotted amount is debited; and the unallotted balance is released promptly. The difference is operational: bank ASBA requires the investor to interact directly with their SCSB (via branch or netbanking); UPI ASBA allows the investor to interact through any UPI app through any broker.

Since May 2022, UPI ASBA has been mandatory for retail individual investors in IPOs. Bank ASBA via SCSB remains available for HNI (High Net Worth Individual) and Qualified Institutional Buyer (QIB) categories.
