Navigating IPO Allotment: Step-by-Step Verification Guide for Investors

MUMBAI / NEW DELHI, NOVEMBER 08, 2026 — During market operations under the Securities and Exchange Board of India (SEBI) T+3 listing framework, retail investors can verify their initial public offering (IPO) share allocation status across three official channels: the appointed Registrar to the Issue, the Bombay Stock Exchange (BSE), and the National Stock Exchange (NSE). Verification relies on an investor’s Permanent Account Number (PAN), application number, or depository participant identification (DP/Client ID) once the designated registrar finalizes the Basis of Allotment.

SEBI T+3 IPO Schedule & Allotment Mechanics

Under SEBI’s standardized T+3 settlement framework, the journey from bidding closure to secondary market trading operates on a strict timetable. Bidding concludes on Day T at 05:00 PM IST. Day T+1 is dedicated to finalizing the Basis of Allotment in consultation with the designated stock exchange. Day T+2 executes demat share credits and fund revocations, culminating in market listing on Day T+3. Prospective applicants can monitor schedules using the live IPO calendar and bidding schedule.

All retail applications operate via Application Supported by Blocked Amount (ASBA)—a mechanism where bid capital remains inside the investor’s own savings bank account under a temporary lien rather than transferring immediately to the issuer. If allocated shares, the bank debits only the specified value. If unallotted, the issuing bank removes the lien, releasing the funds back into free balance.

Step-by-Step Guide: How to Check Allotment Across Platforms

When checking your status, access the official data providers. You can also monitor updates via our centralized IPO allotment status verification hub.

Method 1: The Appointed Registrar Portal

Registrars (such as Link Intime India Private Limited, KFin Technologies Limited, or Bigshare Services Private Limited) are the official transaction agents appointed by the issuing company. They compute the data, process bids, and validate ASBA applications.

• Visit the official online portal of the issue’s designated registrar.
• Select the public issue name from the drop-down menu once the Basis of Allotment is approved.
• Choose your query parameter: PAN, Application Number, or Depository Participant ID (DP ID/Client ID).
• Enter the corresponding alphanumeric identification and the CAPTCHA code, then select ‘Submit’.
• The system outputs the number of shares applied for and the exact count of equity shares allotted.

Method 2: Bombay Stock Exchange (BSE) Verification Portal

The BSE provides an allotment verification module across Mainboard and SME platforms. Access the official investor portal at bseindia.com:

• Navigate to the ‘Status of Issue Application’ page under Investor Services.
• Select ‘Equity’ as the Issue Type.
• Choose the company name from the drop-down list.
• Input your Application Number and valid 10-character PAN.
• Complete the reCAPTCHA authentication and click ‘Search’ to view your allocation status.

Method 3: National Stock Exchange (NSE) Portal

The NSE offers application tracking through its equity platform. Unlike the BSE guest search, the NSE verification system requires a one-time user registration on nseindia.com:

• Log in to the ‘Verify IPO Bids / Allotment Details’ tool with your registered email and password.
• Select the relevant issue name from the list of finalized offerings.
• Enter your PAN and registered DP ID/Client ID.
• Submit the request to view bidding confirmation, verification flags, and shares allocated.

How the Retail Allotment Lottery Operates

Under SEBI ICDR regulations, when the retail category (bids up to ₹2,00,000) experiences oversubscription, allocation shifts from proportional distribution to an automated computer-run lottery. The objective is to allocate at least the minimum bid lot to as many distinct retail applicants as possible.

Consider a hypothetical worked example with round numbers to illustrate the mathematical mechanic:

In this illustrative framework, the computer algorithm picks exactly 20,000 allottees via lottery, each receiving one minimum lot of 50 shares. Applying for multiple lots in an oversubscribed retail category does not improve the mathematical odds of selection, as SEBI rules state each successful retail applicant receives a maximum of one lot until all successful applicants have received one.

Common Pitfalls and Verification Discrepancies

Investors checking their status often encounter temporary discrepancies between banking notifications and portal records. Key factors to note include:

• Bank SMS Before Portal Updates: Often, banks process ASBA debit or mandate revocation messages several hours before the registrar uploads the searchable database online. Receiving a bank debit alert confirms allotment, while an unblocking alert indicates zero allocation.
• Multiple Bids on Single PAN: Submitting multiple retail bids under the same PAN in the same public offering results in automated rejection of all bids by the exchange verification engine. Each PAN can submit only one bid per category.
• UPI Mandate Expiry: If a UPI mandate was not approved before 05:00 PM on closing day, the bid is treated as invalid and will not appear in the Basis of Allotment. Investors exploring broader participation can monitor the open and upcoming IPO calendar to plan bid timing effectively.

Frequently Asked Questions

What Should Investors Check When IPO Allotment Is Delayed?

If an issue does not appear on registrar portals by the scheduled evening of T+1, investors should inspect official regulatory circulars on the BSE or NSE websites. Technical reconciliation delays between sponsor banks and depositories can postpone the public query upload to early morning on T+2 without impacting the final T+3 listing deadline.

How Does the SEBI Basis of Allotment Lottery Work?

When the retail category is oversubscribed, SEBI guidelines dictate an automated lottery where every valid applicant has an equal chance of receiving one minimum lot. Total available retail shares are divided by the minimum lot size to determine the maximum count of allottees, and applicants are selected electronically without human intervention.

Why Are Funds Still Blocked If No Shares Were Allotted?

Lien unblocking relies on your bank executing the sponsor bank’s revocation instruction. While registrars release the unblock schedule on T+2, some public and private banks take an additional 24 to 48 hours to update their core banking systems. If funds remain blocked beyond the listing date, lodge an ASBA complaint with your bank branch quoting your application number and UPI mandate ID.
