For an Indian IPO, applying does not send your money away immediately. ASBA or UPI ASBA normally places a block on the application amount in your own bank account; after the basis of allotment is finalized, the amount for shares you receive is debited and any excess is released. The registrar then reports the result, shares are credited to your demat account if you are successful, and trading starts only when the issue lists.
This guide, updated 17 October 2026, explains the process for Indian public issues. Dates and channel eligibility can change, so the live issue document and its named registrar remain the final authority.
What IPO allotment means
Allotment is the issuer’s final allocation of shares after bidding closes. The registrar reconciles bids and payment-block information, applies the allocation rules for each investor category, and prepares the basis of allotment for approval. Your application is only a request for shares; it is not a promise that shares will be assigned.
The result can be a full allotment, a partial allotment, or no allotment. The basis depends on the issue’s offer document, category rules, bid quantity and demand. Do not describe every IPO as a simple universal lottery, and do not treat an issue’s subscription multiple as a personal probability. No topic-wide allotment success rate is established by the official process guidance.

What happens after you apply: the process in order
1. You submit a bid
You enter the investor category, bid quantity, price details where applicable and other issue particulars through an allowed channel. With a UPI application, you also provide the applicant’s own UPI ID. The bid travels through the intermediary and exchange to the sponsor bank for mandate processing.
2. You authorize the funds block
The sponsor bank sends a UPI mandate request. You must approve it in the UPI app and the bank must validate it. Only then is the bid amount blocked. A bid visible in an intermediary’s application screen, without a successfully authorized mandate, is not proof that funds were blocked or that the application completed.
3. The issue closes and bids are reconciled
After the closing time, bid details move through the exchange and processing systems. The registrar (also called the RTA) processes post-bidding data and reconciles UPI bids with the sponsor bank. This is why an application record, a bank hold and an allotment result can appear in different systems at different times.
4. The basis of allotment is finalized
Demand and the issue’s stated allocation method determine who receives shares and how many. Category quotas and the rules in the current offer document matter. Until the basis is finalized, a successful-looking bid or a debit hold does not establish that shares have been allotted.
5. The final amount is settled
If shares are allotted, the amount payable for those shares is debited from the blocked funds. Any amount blocked above that requirement is released. If you receive no shares, the entire blocked amount is released. In ASBA this is not a conventional refund: the money stayed in your account under a block and the block is removed.
6. Shares are credited and the issue lists
Allotted shares are credited electronically to the demat account identified in the application. They become tradable when the issue lists, subject to the exchange’s and issue’s procedures. A 2024 SEBI-filed offer document states that allotted shares trade only in the dematerialized segment; there is no paper-share step.
ASBA and UPI ASBA: how the money movement differs
Both routes are designed to keep application funds in the investor’s bank account until allocation. The practical difference is how you submit the bid and authorize the block.
Recommended Free Tools
| Point | ASBA through an SCSB | UPI ASBA |
|---|---|---|
| Where you apply | Through a self-certified syndicate bank (SCSB) or its ASBA facility. | Through a permitted intermediary such as a syndicate member, registered stock broker, RTA or depository participant, using the applicant’s UPI ID. |
| How funds are blocked | The SCSB verifies the application and places a bank-account block for the bid amount. | You approve a mandate in your UPI app; the sponsor bank validates it and places the block. |
| While the issue is pending | The blocked money remains in your account and continues to earn interest. | The mandated amount remains blocked in the linked bank account and continues under the bank’s hold until settlement. |
| If you receive shares | The amount for the allotted quantity is debited; the balance is unblocked. | The amount for the allotted quantity is debited; excess is unblocked. |
| If you receive no shares | The block is removed; there is no separate refund transfer. | The full mandate block is released. |
SEBI’s investor guidance describes the principle directly: in ASBA, the amount equal to the applied share price is blocked but remains in the investor’s account until allotment, and the blocked amount continues to earn interest. These routes do not change your probability of allotment; they change the submission and authorization workflow.
When will IPO money be unblocked?
There is no single universal “refund day.” The visible release depends on the issue schedule, the registrar’s processing, and the bank or UPI implementation. Keep these milestones separate:
- Basis finalized: the registrar determines the allocation outcome.
- Debit or unblocking instruction: the amount for allotted shares is debited and excess is released; a non-allotted application is fully unblocked.
- Bank or UPI display: your available balance, lien or mandate screen may update after the instruction reaches your bank.
- Demat credit: allotted shares appear in the specified demat account.
- Listing: the shares become tradable on the exchange.
SEBI’s 2024 offer-document guidance says the T+3 listing timeline is mandatory for public issues opening on or after 1 December 2023. The same guidance says an unsuccessful UPI bidder’s account must be unblocked no later than one working day after the basis of allotment is finalized. Those requirements do not mean every screen updates at the same moment.
A SEBI-hosted specimen offer document from May 2025 contains six-working-day instructions for certain credit and unblocking steps. That wording is an example of offer-document language, not a timetable that overrides the current rules or the dates of a particular live issue. Use the dates printed in the issue’s current document and status notices.

- Find the named registrar. Open the issue’s offer document, exchange notice or application acknowledgement and identify its registrar/RTA. NSE directs investors to that issue-specific service for allotment-related status.
- Open the registrar’s status page for the same issue. Enter the requested identifier, such as PAN, application number or demat details, exactly as used in the bid. The available fields vary by registrar and issue.
- Check the result wording. Look for the allotted quantity, a zero-allotment result, or a status that is still being processed. Save or download the acknowledgement for your records.
- Use the exchange bid-verification facility when appropriate. NSE describes an IPO Bid Verification module that shows bids associated with a PAN. Its FAQ says this data becomes available six days after issue closure. That is a bid-verification availability statement, not a guarantee that the registrar will publish the allotment on that same day.
- Compare systems if the result is unclear. Check the intermediary’s application record, the bank’s lien or hold, the UPI mandate status and the demat account separately. A stale display in one system alone does not prove allotment or failure.
What to do when the UPI mandate or application is pending
No mandate request arrived
Confirm that the UPI ID belongs to the applicant and is linked to the bank account intended for the bid. Check the UPI app’s pending or mandate section and its status page. NSE’s FAQ advises contacting the member through which the bid was placed if the mandate has not arrived. Ask that intermediary to verify whether the bid reached the sponsor bank; do not assume that a submitted form created a valid block.
The mandate was declined or expired
A declined, timed-out or otherwise unapproved mandate does not establish a completed UPI ASBA application. Contact the submitting intermediary promptly and follow the issue’s permitted correction or re-submission process, if still open. Never approve a mandate sent to a different applicant, issue or amount.
The bank shows a hold but the registrar shows no result
Separate the bank lien from the allotment record. A hold proves that funds are reserved; it does not prove that shares were assigned. Check the registrar after its announced publication time, then ask the bank or sponsor bank to trace the mandate and the intermediary to confirm the bid reference.
The registrar shows no allotment but money remains blocked
Keep the registrar result and the bank release request as two separate records. Banks can update the available-balance display later than the registrar. Contact the bank with the application or mandate reference and ask for the release status. If the stated regulatory deadline has passed, escalate through the intermediary and the issue’s investor-grievance channel.

SEBI’s investor guidance says a UPI application should use a bank listed among eligible SCSBs, a listed UPI app and handle, and an allowed submission route: a syndicate member, registered stock broker, RTA or depository participant. For a retail individual investor, the stated UPI limit is ₹5 lakh per transaction.
The UPI ID and bank account must belong to the applicant. SEBI states that a third-party UPI ID or a third-party bank account is not considered for allocation. Enter the issue, category, quantity, PAN and demat details carefully, then verify that the mandate amount and beneficiary name match before approving.
NSE’s ASBA procedure describes SCSBs as accepting and verifying applications, blocking the bid amount, uploading bid details, and later unblocking or transferring the relevant amount after the basis is finalized. NSE also records ASBA as mandatory for issues opening from 1 January 2016. Regulatory limits and eligible channels can change, so recheck the current SEBI instructions and the live issue document before submitting.
What you should expect in each outcome
If you are allotted shares
The registrar’s result shows the quantity allotted. The corresponding amount is debited from the blocked funds, any surplus block is released, and the shares are credited to the demat account. Trading is possible only after the exchange listing, not merely because an allotment message arrived.
If you receive a partial allotment
Only the amount for the allotted quantity is taken. The remainder of the block is released. Check both the quantity in the registrar result and the final debit in the bank account; they should correspond after normal processing updates.
If you receive no shares
The entire ASBA or UPI block should be released. Because ASBA funds were held in your own account, there is normally no separate refund payment. Interest earned while the amount was blocked remains subject to the bank account’s ordinary terms.
A practical checklist before and after applying
- Use only a permitted bank, UPI app and submission channel for the issue.
- Apply with your own PAN-linked details, demat account and account-linked UPI ID.
- Check the issue name, category, quantity, price instructions and mandate amount before approval.
- Save the application number, bid reference and mandate reference.
- Approve the mandate before the issue’s stated deadline; a form submission without authorization is incomplete for UPI ASBA.
- After closure, monitor the registrar’s issue-specific status page rather than relying on a bank hold alone.
- Keep the allotment result, bank debit or unblocking entry and demat credit as separate confirmations.
- Use the current issue document for dates, because listing, credit and release milestones can change with regulatory or operational updates.
Key takeaway
IPO allotment is a post-closing allocation process, not an instant purchase. Your ASBA or UPI ASBA funds are normally blocked—not removed—until the basis is finalized. A successful result leads to a debit for the allotted shares and demat credit; an unsuccessful result leads to release of the block. Check the named registrar for the authoritative allotment result, use NSE’s bid-verification information as a separate check, and treat the issue document’s dates as the schedule that applies to your application.
