For an Indian IPO, submitting an application does not normally transfer your money away immediately. Under ASBA, your bank blocks the application amount in your account; under UPI ASBA, you approve a mandate that places a hold on the funds. After the basis of allotment is finalized, the amount for shares you receive is debited, excess funds are released, and allotted shares are credited to your demat account.
Allotment is not guaranteed. The registrar processes bids after the issue closes, applies the issue’s category-specific rules, and publishes the result. Your bank, UPI app, registrar, demat account and the exchange may update at different times, so treat each milestone separately.

What IPO allotment means
IPO allotment is the allocation of shares among valid applications after a public issue closes. The registrar reconciles bid information, verifies the application data and applies the allocation method described in that issue’s offer document. Demand, investor category, bid validity and the issue’s specific rules determine whether you receive shares and how many.
Applying is therefore a request, not a reservation. Even a correctly submitted application can receive no shares when demand exceeds the shares available for its category. There is no reliable, topic-wide allotment-percentage statistic that can predict an individual result, and subscription multiples alone do not establish your personal probability.

How IPO allotment works, step by step
1. You submit a bid
You enter the issue, investor category, bid quantity, price details where applicable and the demat and bank information required by the permitted application route. For 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
With bank ASBA, the self-certified syndicate bank (SCSB) verifies the application and places a lien or block on the amount in your account. With UPI ASBA, the sponsor bank sends a mandate request to your UPI app. You must approve that request and the mandate must be validated before the amount is blocked.
A bid that was submitted but never received a successfully authorized mandate is not proof that the money was blocked or that the application completed. Check the mandate status in the UPI app and, if necessary, contact the member through which you placed the bid.

After closing, the exchange passes bid details for processing. The registrar (also called the registrar and transfer agent, or RTA) processes post-bidding records and reconciles UPI bids with the sponsor bank. Invalid, duplicate or otherwise non-compliant records can be excluded under the issue rules.
4. The basis of allotment is finalized
The basis of allotment sets out which valid applicants receive shares and the quantity allocated to each category. Do not assume every IPO uses one universal lottery. Retail, non-institutional and other categories can have different rules, and the current issue’s offer document controls.

5. Funds are settled
If shares are allotted, the amount needed for those shares is debited from the blocked funds. Any balance that was blocked but is not required is released. If you receive no shares, the blocked amount is released in full. In a normal ASBA flow, this is not a conventional refund because the money remained in your account while it was blocked.
6. Shares are credited and the issue lists
Allotted shares are credited electronically to the demat account specified in the application. They become tradable when the issue lists, subject to the exchange’s procedures and the dates in the live issue timetable. Shares allotted in a public issue are traded in dematerialized form.
Does IPO application money leave your bank account?
Normally, no. In ASBA, the amount up to the value of the shares applied for is blocked in your bank account and remains there until allotment. Because it remains in the account, the blocked amount continues to earn interest under the account’s normal terms. Only the amount corresponding to shares actually allotted is debited; the remainder is unblocked.
UPI ASBA uses the same economic principle through a UPI mandate. You approve a hold rather than sending the full application amount to the issuer at the moment you bid. Following allocation, the amount for allotted shares is debited and the excess hold is removed.
ASBA and UPI ASBA compared
| Point | Bank ASBA | UPI ASBA |
|---|---|---|
| Where you apply | Through an eligible SCSB or its ASBA facility. | Through an allowed intermediary such as a syndicate member, registered stock broker, RTA or depository participant, using an eligible UPI route. |
| How funds are authorized | The SCSB verifies the form and blocks the bid amount in the linked bank account. | You enter your own UPI ID and approve a sponsor-bank mandate in the UPI app; the bank then places the block. |
| What you must verify | Correct issue and bid details, account ownership, sufficient balance and successful bank blocking. | Correct issue and bid details, applicant-owned UPI ID, eligible bank and app, successful mandate authorization and sufficient balance. |
| After allotment | Allotted amount is debited and the unused block is released. | Allotted amount is debited and the unused mandate amount is unblocked. |
| Effect on allotment odds | Neither route, by itself, increases or decreases the probability of receiving shares. | |
NSE describes SCSBs as accepting and verifying ASBA applications, blocking the bid amount, uploading bid details and later unblocking or transferring the relevant amount after the basis of allotment is finalized. ASBA has been mandatory for issues opening from 1 January 2016.
Who can use UPI ASBA and what limits apply?
SEBI investor guidance says a UPI application should use a bank listed among eligible SCSBs, a listed UPI app and handle, and an allowed submission channel: a syndicate member, registered stock broker, RTA or depository participant. For a retail individual investor, the stated UPI limit is ₹5 lakh per transaction. Regulatory limits and eligible channels can change, so confirm the current instructions for the specific issue.
- Use a UPI ID linked to the applicant’s own bank account.
- Use the eligible bank, UPI app and submission channel specified for the issue.
- Check that the mandate identifies the correct IPO, amount and applicant.
- Approve the mandate within the app and confirm that its status is successful.
- Keep enough balance available until the allotment and debit process is complete.
A third-party UPI ID or a third-party bank account is not considered for allocation under the cited SEBI guidance. A family member’s account or someone else’s UPI handle can therefore make the application ineligible even if the bid screen appeared to accept it.
When will IPO money be unblocked or debited?
There is no universal “refund day” that applies to every issue. The date you see depends on the issue schedule, the registrar’s processing, the bank or sponsor-bank implementation and the time at which each system refreshes.
SEBI’s 2024 offer-document guidance made a T+3 listing timeline mandatory for public issues opening on or after 1 December 2023. In the same guidance, unsuccessful UPI bidders’ accounts are to be unblocked no later than one working day after the basis of allotment is finalized. These are regulatory milestones, not a promise that your bank balance, UPI mandate, registrar page, demat credit and listing status will change simultaneously.
A SEBI-hosted offer-document specimen from May 2025 contains six-working-day instructions for certain share-credit and unblocking steps. That wording is an example of offer-document language, not a timetable that overrides the live issue’s schedule or later regulatory changes. Use the dates in the current issue document and the registrar’s notice for a specific IPO.

How the milestones differ
- Basis of allotment finalized: the registrar has determined who receives shares.
- Funds debited or unblocked: the bank or sponsor bank settles the amount based on that result.
- Shares credited: the depository records the allotted shares in your demat account.
- Listing: the exchange admits the shares for trading on the announced listing date.
One milestone can appear before another in the interface you are watching. A pending bank lien does not prove that you were allotted shares, and a delayed demat display does not by itself prove that you were rejected.
How to check your IPO allotment status
- Find the registrar named in the issue materials. Open the registrar’s issue-specific status service and enter the requested details, such as PAN, application number or demat information.
- Check the result after the registrar publishes it. The registrar is the primary place for allotment-related status; the exact publication time follows the issue timetable.
- Use the exchange bid-verification facility when relevant. NSE describes an IPO Bid Verification module that shows bids associated with a PAN. Its FAQ says the data becomes available six days after issue closure. This is a bid-data tool, not a guarantee of the final allotment time.
- Check the bank or UPI app separately. Look for the lien, mandate or debit status. A successful allotment should ultimately show the allotted debit, while an unsuccessful application should show release of the hold.
- Check the demat account. Once credited, the shares should appear in the demat account used in the application. Trading remains unavailable until the issue lists.
What happens if you do not get an IPO allotment?
If no shares are allotted, the blocked amount should be released. Under ASBA, there is normally no separate refund transaction because your money stayed in the account under a block. Under UPI ASBA, the mandate amount should be unblocked. The visible release can lag behind the registrar result because the bank or sponsor bank must complete its settlement process.
If only part of your requested quantity is allotted, the amount for that portion is debited and the unused balance is released. Check the allotment quantity and the debit amount together rather than relying on either screen alone.

The UPI mandate never arrived
Confirm that the UPI ID was entered correctly, the app and handle are eligible, and the bank account has sufficient funds. Check the UPI app’s pending requests and status page. If no mandate appears, contact the member through which you placed the bid, as NSE’s FAQ directs applicants to do.

Do not treat the original bid submission as confirmation of completion. Record the application number, mandate reference and time of submission, then ask the intermediary or sponsor bank whether the bid was reconciled. A failed or unapproved mandate can leave no valid blocked application for allotment.

The registrar shows no result
Verify that you are using the registrar named in the issue documents and that the result window has opened. Re-enter the PAN or application details exactly as submitted. If the page remains unavailable, the intermediary can confirm whether the bid was uploaded and accepted.
The money still appears blocked
Separate the application record from the bank lien or UPI mandate. Check whether the basis of allotment has been finalized, whether a debit has already been posted, and whether the unblocking deadline in the issue documents has passed. Then contact the bank or sponsor bank with the mandate or application reference. A stale display in one system alone does not establish an allotment or a failed application.
The shares are not visible in demat
Compare the demat account details in the application with the account you are checking. Allow for the issue’s stated credit date and distinguish credit from listing: shares may be credited before they are tradable. If the registrar records an allotment but the credit is missing after the announced date, raise the issue with the depository participant and registrar.

- The bank account has enough available balance for the full block.
- The bank, UPI app and submission channel are currently eligible.
- The UPI ID belongs to the applicant and is linked to the bank account being used.
- The mandate is approved successfully, not merely displayed as requested or pending.
- You have saved the application, mandate and confirmation references.
What to expect after a successful allotment
The registrar’s result should show the quantity allotted. The bank or sponsor bank then debits the corresponding amount, the demat account receives the shares in electronic form, and the exchange lists the issue according to the published timetable. The shares are not tradable merely because an allotment message appeared; listing procedures still apply.
For a current IPO, rely on the issue’s offer document, registrar notice and exchange announcement for the operative dates. General regulatory milestones explain the sequence, but they do not replace the live calendar.
Key takeaways for Indian retail applicants
- ASBA and UPI ASBA block money rather than normally sending it away when you apply.
- Only the value of shares actually allotted is debited; unused blocked funds are released.
- Allotment is decided after the issue closes and is not guaranteed by submitting a valid bid.
- Use the named registrar for the allotment result and the exchange’s bid-verification facility for bid information where available.
- Do not promise yourself a single refund date: follow the issue-specific schedule and distinguish unblocking, debit, demat credit and listing.
- Never use a third-party UPI ID or bank account for an application intended to be allocated to you.
Frequently Asked Questions
Can I withdraw an IPO application after approving the UPI mandate?
Withdrawal, modification and cancellation rules depend on the issue stage and the intermediary’s process. Check the current issue document and contact the member through which you applied; do not assume that deleting the UPI request alone cancels the bid.
Does a higher subscription multiple guarantee that I will not receive shares?
No. Subscription data does not determine an individual result. The registrar applies the issue’s category-specific basis of allotment to valid bids.
Is an IPO allotment message the same as a listing confirmation?
No. Allotment confirms the quantity assigned to you. The shares must still be credited to the demat account and admitted for trading on the exchange on the announced listing date.
