To apply for an Indian IPO, submit your bid through an authorised intermediary, provide your PAN and demat details, choose the quantity and price (or cut-off option where the issue permits), and authorise a block of funds through either UPI or ASBA. UPI sends a block mandate to your eligible UPI app for approval with a UPI PIN. ASBA instructs an eligible bank to block the money in your account. Only the amount due for shares actually allotted is debited; any remaining blocked amount is released.
This guide explains both procedures, the eligibility rules that can cause rejection, how to choose between them, and what to do when you cannot or do not want to use UPI.
What UPI and ASBA do in an IPO application
Neither method transfers the full application amount immediately. Each places a hold on funds while the issue is processed. The block protects the application without taking the money permanently before allotment.
- UPI: the sponsor or escrow bank sends a mandate request to your UPI application. You approve it with your UPI PIN, and the linked bank account is blocked for the application amount.
- ASBA: an ASBA-enabled bank blocks the amount in your account after you authorise the application. The money stays in that account until the allotment decision.
After allotment, the amount corresponding to the shares allotted is debited. If you receive fewer shares than requested, the balance is released. If you receive no shares, the entire blocked amount is released. SEBI Investor describes ASBA as keeping the blocked money in the investor’s account until allotment; the blocked amount continues to earn interest and no separate refund is required when there is no allotment.

Your application is a bid, not a guarantee of shares. Allotment depends on the issue rules and demand. This procedure guide does not assess whether any IPO is a suitable investment.
Information and accounts you need before starting
Have the following details ready before opening the application:
- Your PAN, entered exactly as recorded in the intermediary and depository records.
- Your demat account details, so allotted shares can be credited.
- The bank account that will be used to block the funds.
- The bid quantity and price, or the cut-off choice if that issue permits it.
- For UPI, your own eligible UPI ID and the UPI application linked to the bank account.
- For ASBA, an account with an ASBA-enabled Self-Certified Syndicate Bank (SCSB) and access to its designated branch or online ASBA facility.
Keep enough clear funds available for the full application amount before submitting. A balance that is unavailable because of another hold or pending transaction may not satisfy the block request.
How to apply for an IPO through UPI
1. Open the issue application with an authorised intermediary
Use a permitted syndicate member, registered stockbroker, registrar and transfer agent, or depository participant. The exact channels offered can vary by issue, so use the options stated in that IPO’s current documents.
2. Enter the bid and identity details
Enter the number of shares, the bid price or cut-off selection allowed by the issue, your PAN, demat details and your own eligible UPI ID. Check every character before submission. A mismatch between the application, PAN, demat account or bank-linked UPI details can prevent processing.
3. Submit the bid and wait for the mandate
After submission, the sponsor or escrow bank sends a block mandate request to the UPI application associated with the ID you entered. The request may not appear in the same screen used to place the bid; open the UPI app and check its pending mandate or approval area.

4. Approve the mandate with your UPI PIN
Review the IPO name, applicant information and amount in the request. Authorise it with your UPI PIN only when the details match your application. Approval blocks the application amount in the linked bank account; it does not mean the shares have been allotted.
5. Keep the application and mandate references
Save the application number and the mandate status. They are the identifiers to use when checking whether the bid was received, whether the block is active and whether a release is pending.
6. What happens after allotment
If shares are allotted, the amount needed for those shares is debited and any excess is unblocked. If there is no allotment, the blocked amount is released. The dates for mandate approval, allotment and release are issue-specific; follow the timetable in the prospectus or the registrar’s notice.
UPI limits and eligibility rules
SEBI Investor’s current guidance accessed in 2026 sets a limit of ₹5 lakh per transaction for UPI IPO applications by retail individual investors. The ceiling is per transaction and applies to the retail individual category described by that guidance. An issue can also impose its own category, bid and timing rules.
Use only UPI applications and handles appearing on SEBI’s current eligible lists and in the issue documentation. The UPI ID must belong to the applicant, and the linked bank account must also be the applicant’s own account. SEBI states that a third-party UPI ID or third-party bank account will not be considered for allocation.
Eligibility lists, participating banks and regulatory limits can change. Check the current SEBI information and the IPO’s own documents immediately before applying rather than relying on an old list or a UPI app that worked for a previous issue.

How to apply for an IPO through ASBA
1. Confirm that your bank supports ASBA for the issue
ASBA applications use an SCSB. Start with an ASBA-enabled Self-Certified Syndicate Bank and use its designated branch or online ASBA facility, subject to the issue’s instructions. A normal bank account alone is not enough if the bank or channel is not authorised for that IPO.
2. Open the ASBA form or online application
Select the IPO named in the bank’s ASBA channel. Enter the bid quantity, price or permitted cut-off option, PAN, demat account and bank-account details. The name and account information should match the records used by the bank and depository.
3. Authorise the block
Submit the form or confirm the online instruction authorising the bank to block the application amount. The bank places the hold in your account instead of transferring the money to the issue at this stage.

Do not withdraw or otherwise commit the amount while the ASBA block is active. The blocked money remains in your account and continues to earn interest under the ASBA process, but it cannot be used for another transaction until released.
5. Check allotment and release
On allotment, the bank debits the amount due for the shares allotted. The unused balance is released. If there is no allotment, the block is released without a separate refund process. Consult the issue timetable or registrar notice for the relevant dates.
UPI versus ASBA: which route fits your situation?
| Comparison point | UPI | ASBA |
|---|---|---|
| Main action | Approve a mandate in an eligible UPI app with a UPI PIN. | Authorise a bank-account block through an ASBA-enabled bank. |
| How funds are handled | The application amount is blocked after mandate approval; only the amount for allotted shares is debited. | The bank blocks the amount in the account; the amount due is debited on allotment. |
| Eligibility constraint | Requires an eligible bank, app and handle, your own UPI and bank account, and a ₹5 lakh per-transaction ceiling for retail individual investors under SEBI’s cited guidance. | Requires an ASBA-enabled SCSB and the issue-designated branch or online facility. |
| Practical dependency | You must receive and approve the mandate before the issue’s stated deadline. | You must be able to access the bank’s ASBA channel and enter the account and bid details correctly. |
| When it is a practical fit | Useful when you want a mobile mandate workflow and satisfy the UPI eligibility and limit requirements. | Useful when you prefer a bank-led process, cannot use UPI, or need a route outside the retail UPI ceiling. |
“Best fit” here describes the documented mechanics and constraints, not an investment recommendation. Both routes require accurate identity and demat information, sufficient funds and compliance with the particular issue’s instructions.

How to apply without UPI
Choose ASBA. Open the IPO through an ASBA-enabled SCSB’s designated branch or online ASBA facility, complete the bid and identity fields, and authorise the block from your bank account. The ASBA method does not require a UPI ID, UPI application or UPI PIN.

If the issue’s instructions do not list your bank or channel, do not assume that a regular internet-banking transfer or an ordinary account hold is an ASBA application.
Checks that prevent rejection or an incomplete block
Identity and ownership
- Use the applicant’s PAN exactly as recorded.
- Match the applicant name, PAN and demat details across the application and depository records.
- For UPI, enter only the applicant’s own UPI ID.
- Use the applicant’s own linked bank account; do not substitute a family member’s or another person’s account.
Eligibility and channel
- Confirm that the bank and UPI app or handle appear on the current eligible lists when using UPI.
- For ASBA, confirm that the bank is an SCSB and that the branch or online facility is designated for the issue.
- Check the category you are applying under and any issue-specific bid or price rules.
Money and timing
- Keep clear funds available for the full application amount before submitting.
- Approve the UPI mandate before the IPO’s stated deadline; submitting a bid without approving its mandate does not complete the UPI process.
- Use the exact dates in the prospectus or registrar notice for bid closure, mandate approval, allotment and release.
Records
- Save the application number.
- Record the UPI mandate status or ASBA acknowledgement.
- Keep the issue name and bid details so you can compare them with the allotment and debit information.
Troubleshooting common failure points
The UPI mandate does not appear
Verify that the UPI ID entered in the bid is your own and is linked to the intended bank account. Check the UPI app’s pending-mandate area rather than only its payment history. Confirm that the app and handle are eligible for IPO applications, then check the issue’s stated approval deadline. Keep the application number and contact the authorised intermediary or registrar using the channel named in the issue documents if the request remains absent.
The mandate is visible but approval fails
Check the amount and applicant details shown in the request, confirm that sufficient clear funds are available, and use the correct UPI PIN. Do not approve a request whose IPO or applicant information does not match your bid. If the deadline is approaching, follow the intermediary’s documented correction or re-submission procedure rather than creating a third-party application.
The application is rejected because of ownership details
Review the PAN, demat account, bank account and UPI ownership as one set. A third-party UPI ID or bank account is not eligible for allocation under SEBI’s stated rule. Correct the details only through the authorised application channel and within the issue’s permitted window.
Recommended Free Tools
The ASBA block is not visible
Confirm that you used the SCSB’s designated branch or online ASBA facility and selected the correct IPO. Check the bank’s acknowledgement and account block status. If the bank channel was not designated for that issue, an ordinary payment or transfer does not replace an ASBA instruction; ask the bank how to submit through its authorised ASBA route before the closing time.

The block remains after allotment
Compare the status with the issue’s published allotment and release dates. A block can remain until the bank or UPI system processes the release. Use the saved application or mandate reference when contacting the authorised intermediary, bank or registrar. Do not submit a duplicate application merely because the release is not yet visible.
Understanding allotment, debit and release
The block is a reservation of funds, not an advance purchase. The final debit is limited to the price of the shares allotted under the issue’s rules. Any amount covering shares not allotted is released, and a complete non-allotment releases the entire block. With ASBA, the funds remain in the account during the block and continue to earn interest; there is no separate refund request for a non-allotment.
UPI and ASBA therefore differ mainly in how you create and monitor the block: UPI requires an app-based mandate approval, while ASBA uses the bank’s authorised blocking facility. The result after allotment—debit only what is due and release the remainder—is designed to work the same way.

Dates and rules to verify for every IPO
Do not carry assumptions from one issue to another. Before applying, read the current prospectus or registrar notice for:
- Opening and closing dates for bids.
- The final time by which a UPI mandate must be approved.
- Permitted categories, quantities, prices and cut-off selections.
- Eligible UPI apps, handles, banks and ASBA channels.
- Allotment, debit and fund-release dates.
SEBI limits, intermediary participation and issue timetables can change. The current official documents for the specific IPO control when they differ from a general explanation.
