If an IPO application was rejected, or the allotment shown does not match your records, do not automatically complain to your bank first. Identify the participant that handled the disputed step: the IPO registrar, the bank or SCSB that processed an ASBA application, the UPI or application intermediary, the broker, or the stock exchange. For most bid and allotment disputes, write to the registrar to the issue and copy the designated intermediary. A bank complaint is the right starting point when the evidence indicates an ASBA, account-blocking or payment-processing failure.
Check the registrar’s status and stated rejection reason against your acknowledgement, bid details and bank or UPI records. A valid application can receive no shares because of oversubscription; that is different from a rejected bid or an incorrect allotment. A complaint can seek correction or an explanation, but it cannot guarantee shares or compensation.

Who should receive your IPO complaint?
The correct recipient depends on where the process appears to have failed. Use this routing decision before sending documents:

SEBI’s issue-grievance guidance generally routes bid and allotment complaints to the issue registrar, with a copy to the designated intermediary. Where a registered broker submitted the bid, the guidance allows the grievance to be addressed to the stock exchange, with a copy to the registrar. A bank is not automatically responsible for every non-allotment.
#1 Best Overall
First establish what happened
Rejected application
A rejection means the bid was not accepted for allotment processing. The registrar, exchange, broker or bank should display a status or reason. Technical grounds in an issue’s offer documents can include incomplete bid or bank details, invalid payment instructions, a third-party bank or UPI arrangement, and a bid submitted after the permitted window. The exact grounds and wording differ by issue, so read that IPO’s offer document and compare the stated reason with your records before alleging an error.
Valid application with no shares
Non-allotment is not, by itself, evidence of a mistake. In an oversubscribed issue, a properly submitted application can receive zero shares under the issue’s allocation rules. For ASBA, the application amount is blocked in your account rather than sent away. If no shares are allotted, the block is released; there is no separate refund because the money remained in the account. On allotment, only the amount needed for the allotted shares is debited.
“In ASBA, money to the extent of price of the shares for which the investor has applied, is blocked, but it remains in their account till allotment.” — SEBI Investor, “Apply in IPO through ASBA.”

Incorrect allotment or incorrect bid data
An incorrect outcome may involve the wrong quantity, category, PAN, demat details or application status being recorded. Preserve the original acknowledgement and the final status page. The registrar is usually best placed to reconcile the bid record, while the intermediary that accepted the application can confirm how it transmitted the details.
Step 1: collect a complete application trail
Before writing, assemble a single folder containing the bid identifiers, transaction evidence and every response you have received. Record the following:
Rank #2
- Ideal for Gifting
- Ideal for a bookworm
- Compact for travelling
- IPO name and, if shown, issue or symbol details.
- Sole or first applicant’s name and PAN.
- Application or bid-cum-application number.
- Application date and the channel used: ASBA, UPI, broker, bank or another registered intermediary.
- Number of shares applied for, price or price-band choice, category and bid details.
- DP ID and Client ID for the demat account.
- UPI ID and mandate request, approval, failure or cancellation reference when UPI was used.
- ASBA bank and account details for a non-UPI ASBA application. Do not send the full account number unless the bank’s secure complaint channel requires it; provide the masked details and the reference first.
- Designated intermediary, broker or exchange name.
- Application acknowledgement slip or acknowledgement number.
- Registrar, exchange, broker or bank status page showing rejection, allotment or non-allotment and the stated reason.
- Bank statement or transaction record showing an ASBA block, debit, release or failed block; include dates and reference numbers.
- Copies of previous emails, complaint numbers and written replies.
SEBI’s issue-grievance wording specifically calls for the applicant’s identifying details, bid number, DP ID, Client ID, UPI ID where applicable, PAN, submission date, address, quantity, intermediary, ASBA account details for non-UPI applications and the acknowledgement slip or number. Attach only documents that support the allegation you are making.
Step 2: reconcile the status with your records
- Open the official allotment or application-status channel. Use the registrar, exchange, broker or bank channel associated with the issue, and save a dated copy or screenshot of the result.
- Match the application number. Make sure the status belongs to your bid, not another application, PAN, demat account or UPI ID.
- Read the precise reason. Distinguish “not allotted” from “rejected,” and record the exact wording, date and quantity shown.
- Check the payment trail. For ASBA, verify whether the amount was blocked and later released or debited. For UPI, verify that the mandate was created for the correct amount, approved before the deadline and linked to the same bid.
- Compare submitted details. Check PAN, category, bid quantity, bank account, demat identifiers and applicant name against the acknowledgement and your account records.
- Identify the first point of failure. A missing block points toward the SCSB or payment path; a correctly blocked amount with a registrar rejection may point to bid data or an issue rule; a broker acknowledgement with no matching registrar record may require the exchange and broker to investigate.
Do not disclose passwords, UPI PINs, one-time passwords or complete card credentials. A legitimate initial complaint should be traceable through bid, mandate and transaction references without those secrets.

When the ASBA bank or SCSB is the likely cause
Write to the bank’s IPO or ASBA grievance contact when funds were not blocked despite a timely application, the bank processed the bid incorrectly, or the bank failed to transmit or act on the application. State the account’s relevant masked details, application number, date, amount, branch or digital channel and the exact failure. Attach the acknowledgement and evidence of the missing, failed or incorrectly released block. Copy the registrar if the failure caused the bid to be rejected or omitted from allotment consideration.
Keep the bank’s written acknowledgement. If an SCSB failure caused an ASBA bid not to be considered, the cited SEBI guidance says redress may be sought from that SCSB within three months of listing. Treat that as a time-sensitive period: send the complaint promptly and retain proof of delivery.
When a UPI or payment intermediary is involved
Send the complaint to the bank or intermediary that handled the mandate or authentication, and copy the registrar about the resulting bid status. Include the UPI ID, mandate request and approval or error timestamps, transaction reference, application number and the deadline that applied. Explain whether the mandate was approved, rejected, expired, cancelled or approved for a different amount. A mandate approval alone does not prove that the registrar received a valid bid; the application acknowledgement and final status must also match.
Rank #3
When the registrar shows rejection or a wrong allotment
Address the main complaint to the registrar to the issue and copy the designated intermediary. Ask the registrar to verify the bid record against the acknowledgement, PAN, demat details, category, quantity and payment status. Quote the displayed rejection reason or the discrepancy in the allotment statement. If you believe a technical rejection was applied incorrectly, identify the specific field or event that contradicts your evidence rather than simply stating that no shares were received.
When a registered broker submitted the bid
Retain the broker’s submission acknowledgement and raise the issue through the stock exchange route described in the issue-grievance guidance, copying the registrar. Ask the broker to confirm the time and data it transmitted, while asking the registrar to confirm whether that bid was received and how it was treated. This creates a record with both the submitting intermediary and the entity that processed the issue data.
How to write an effective complaint
Use a subject that lets the recipient locate the case, such as “IPO application [number] — disputed rejection or allotment — [issue name].” Put the requested remedy in the first paragraph. A concise complaint can follow this order:
- Identify the applicant and issue: name, PAN, IPO, application number, date, category, quantity, DP ID and Client ID.
- Describe the expected event: for example, “The ASBA amount should have been blocked before the closing time,” or “The registrar status shows 100 shares allotted, but the demat credit is for 50.”
- State the observed result: quote the status and rejection reason exactly, with its date.
- List the evidence: acknowledgement number, ASBA block or release reference, UPI mandate reference, broker receipt, bank statement entry and screenshots.
- Ask for a specific action: verify the bid record, explain the rule applied, correct an input error if supported, confirm the release or debit, or provide the formal reason for rejection.
- Request a written response: ask for a complaint number and the name or department handling it.
Send the complaint through the participant’s current official channel, such as its secure portal, listed email or branch process. Save the sent message, attachments, delivery confirmation and any ticket number. Do not send the same allegation separately to multiple recipients without identifying the earlier ticket; cross-reference every related complaint so the records can be reconciled.
Escalate an unresolved securities-market complaint through SCORES
SCORES is SEBI’s online grievance mechanism for eligible complaints against SEBI-regulated entities and market infrastructure institutions. It is an escalation and tracking route, not a promise of allotment and not a damages award. First approach the concerned registrar, bank, broker, exchange or other entity and preserve its response.
Rank #4
- Prepare the prior complaint record. Include the entity’s name, complaint number, date sent, response and the documents that establish the disputed bid.
- Lodge the eligible complaint on SCORES. Describe the event chronologically and identify the regulated entity. Upload legible evidence without passwords, PINs, OTPs or unnecessary credentials.
- Track the action-taken report. The current SCORES FAQ says the entity must submit an action-taken report within 21 calendar days.
- Review an unsatisfactory response. If the report does not resolve the issue, the portal provides review steps. The same FAQ gives 15 calendar days from the action-taken report to request a review.
- Keep the portal record. Save the SCORES complaint number, uploaded documents, action-taken report and review submission for any later correspondence.
SCORES cannot compel an allotment where the issue’s allocation rules produced a valid non-allotment. Its value is that it creates a formal, trackable review of whether the regulated participant handled the application and grievance properly.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.When a bank-service complaint may require the RBI route
A complaint about a bank’s service—such as failure to process an ASBA instruction, mishandling a payment or not resolving a service request—may fall under the RBI banking complaint mechanism rather than SCORES. The current eligibility conditions, waiting periods, deadlines and submission sequence can change, and they depend on the type of bank complaint. Check the live RBI complaint-management guidance and the bank’s current grievance policy before escalating. Include your bank ticket, the bank’s final response or evidence of non-response, and the application and payment records.
Keep the securities-market and bank-service issues distinct. The registrar or exchange addresses whether the IPO bid was received, rejected or allotted; the bank route addresses the bank’s service conduct. A single chronology can reference both, but each complaint should ask the appropriate institution to decide the part within its authority.
Common scenarios and the practical next move
“My IPO UPI mandate was approved, but the application was rejected.”
Save the mandate approval and transaction reference, then obtain the registrar’s exact rejection reason. Send the bid identifiers and mandate evidence to the registrar and the bank or application intermediary that handled the UPI flow. Ask them to confirm whether the approved mandate was linked to the correct bid and whether any separate bid-data or timing failure caused rejection.

“The amount was blocked, but no shares were allotted.”
Check whether the status says non-allotment rather than rejection. If the application was valid, zero shares can result from the issue’s allocation rules. Confirm that the block was released and that no debit remains. Escalate only if the status, block record or release does not match the application details.
Best Value
- It can be a gift option
- Comes with secure packaging
- Helpful in various ways
“The registrar shows a rejection, but my acknowledgement is complete.”
Send the acknowledgement, application number, PAN, category, quantity, demat details and the stated rejection reason to the registrar and designated intermediary. Ask which field or rule produced the rejection and request correction if your evidence shows a transmission or recording error.
“The ASBA bank never blocked the application amount.”
Complain to the SCSB promptly with the account, application, date, amount and failed-block evidence, and copy the registrar if the missing block prevented consideration. Retain the bank acknowledgement, particularly where the issue’s listing date affects the three-month period described in the SEBI guidance.
“The allotted quantity or demat credit is wrong.”
Compare the registrar’s allotment statement with the demat credit and your application quantity and category. Ask the registrar to reconcile the allotment file and ask the depository participant or intermediary to confirm the credit entry. Attach statements showing the discrepancy, not unrelated account information.
What a successful complaint can and cannot achieve
- It can obtain a traceable explanation of the rejection, payment handling or allotment record.
- It can expose a transmission, recording or processing error for correction where the participant has authority to correct it.
- It can establish whether a bank, intermediary, broker, exchange or registrar handled the disputed step.
- It cannot turn a valid non-allotment into an allotment when the issue’s allocation rules produced no shares.
- It cannot guarantee compensation; any remedy depends on the facts, applicable rules and the institution’s findings.
The strongest complaint is specific, timely and document-backed: identify the exact bid, show the conflicting records, send it to the participant that controlled that step, and escalate through the appropriate securities or banking mechanism only after creating that first written record.
