IPO Allotment Process
Learn exactly how SEBI governs IPO allotment — from subscription closure to shares landing in your Demat account.
The Allotment Timeline (T+6 Days)
IPO Subscription Window Closes
Once the IPO subscription period ends (typically 3 days), the registrar compiles all valid bids received via ASBA and UPI. Invalid bids (duplicate PAN, incomplete UPI mandate, etc.) are rejected at this stage.
Basis of Allotment Finalised
The registrar, along with SEBI, determines the Basis of Allotment. For oversubscribed issues, retail allotment is done via computerised lottery. For undersubscribed issues, all applicants get full allotment.
Allotment Notification (T+6)
Allotment confirmation is sent via SMS and email. You can check your allotment status on BSE, NSE, or the registrar's website using your PAN, application number, or Demat account number.
Refund for Non-Allotment
If you are not allotted shares, the blocked amount in your bank account is unblocked within 6 business days of allotment. No manual refund request is needed — ASBA handles this automatically.
Shares Credited to Demat
Allotted shares are credited to your Demat account one working day before listing. You will receive a confirmation from your Depository Participant (DP) — either NSDL or CDSL.
Listing on NSE / BSE
Shares begin trading on the stock exchange on listing day (T+6 from closure). The opening price is determined by a pre-open session from 9:00–9:45 AM. Investors can sell on listing or hold for long term.

- !Ensure your UPI ID is linked to an active bank account with sufficient funds.
- !Accept the UPI block mandate within the stipulated time (usually within 3–4 hours on the same day).
- !Verify that your Demat account is active and not frozen before applying.
- !Ensure your PAN is linked to Aadhaar — this is mandatory for KYC compliance.
Frequently Asked Questions
If I apply from multiple accounts, will I get multiple allotments?
Applying from multiple accounts with the same PAN is not allowed and will result in rejection of all applications linked to that PAN. Each PAN can have only one application per IPO.
Does applying for more lots improve allotment chances?
In the retail category, allotment is done by lottery at the minimum lot level. Applying for more lots increases your chances slightly only if the issue is not fully oversubscribed in the lottery.
How long does the entire allotment process take?
SEBI mandates the entire process — from IPO close to listing — to be completed within T+6 working days. Most modern IPOs complete in exactly 6 days.
What if my UPI mandate is not approved in time?
If your UPI mandate is not approved within the given window, your application will be considered invalid and rejected. Always accept UPI mandates promptly after applying.
