IPO Allotment in India: How to Maximize Your Chances (2027)
IPO allotment is a lottery, not luck. How SEBI's system works, why one PAN means one application, and the UPI mandate, cut-off price and demat details that decide yours.

IPO season arrives, everyone wants a piece of the action, and most retail investors walk away empty-handed. The truth? Allotment is not luck — it is a lottery with rules, and knowing the rules is how you stop losing tickets you were entitled to.
Key takeaways
- One PAN equals one application — duplicate applications across brokers or banks get all of them rejected.
- Retail category (up to Rs 2 lakh) has the best per-application odds; sNII is Rs 2-10 lakh and bNII above Rs 10 lakh.
- Retail bidders should always select cut-off price; non-retail bidders must bid a specific price within the band.
- Approve the UPI mandate before 5:00 PM on the IPO closing day — a submitted bid without mandate approval is cancelled.
- The demat account must be active with clean KYC; inactive or frozen accounts cause automatic rejection.
- Each additional PAN is one more lottery entry: family accounts, minor accounts (via guardian) and genuine HUF accounts multiply tickets legitimately.
- Mainboard IPOs now run on T+3: bidding closes 5 PM on T day, allotment T+1, listing T+3 (SEBI, since December 2023).
Understanding the IPO allotment process
When an IPO is oversubscribed, shares cannot go to everyone, so the allotment becomes a lottery among valid applications — but only among applications that survive the checks. Here is the sequence:
How the SEBI lottery system works
1. Every valid application gets at least one chance in the draw
1. Each unique PAN gets ONE lottery entry in the retail pool
1. When oversubscribed, the registrar randomly selects winners from these entries
1. First, everyone in the pool gets one lot; then excess lots are distributed proportionally (in the sNII and bNII pools)
The system is run by the issue registrar under exchange supervision, and the draw is genuinely random — but the entry fee is a technically perfect application.
The investor categories
| Category | Application value | Notes |
|---|---|---|
| Retail (RII) | Up to Rs 2 lakh | Highest per-application odds; UPI allowed |
| sNII (small HNI) | Above Rs 2 lakh, up to Rs 10 lakh | One-third of NII quota |
| bNII (big HNI) | Above Rs 10 lakh | Proportional allotment |
Retail gets a reserved quota and lottery-style allotment of minimum lots; the NII sub-categories (sNII up to Rs 10 lakh, bNII above) get proportional allotment, which is why a big HNI bid is not automatically a big allotment.

The golden rules
Rule 1: One PAN = one application
This is the most critical rule. Multiple applications with the same PAN — through different demat accounts, different brokers, different bank accounts — means ALL of them are rejected. Ensure your bank account PAN and demat account PAN match exactly.
The only legitimate way to multiply tickets is multiple PANs: separate adult family members, an HUF with its own PAN, or a minor account with a guardian.
Rule 2: Choose the right category and bid at cut-off (retail)
- Retail (up to Rs 2 lakh): always select "Cut-off" price. Cut-off means "accept whatever final price the book settles at", so your application stays valid no matter where the price lands.
- sNII/bNII (above Rs 2 lakh): bid at a specific price within the band — the cut-off option is not available to non-retail bidders.
Bidding below the final issue price in a book-built IPO gets your application rejected outright, which is exactly what cut-off protects retail investors from.
Rule 3: UPI mandate — approve before 5 PM on closing day
For retail applications paid through UPI, placing the bid on the broker's app is not enough. You must approve the mandate request on your UPI app, and the mandate acceptance window expires at 5:00 PM on the IPO closing day. Miss it and the application is cancelled — the broker will still show "submitted".
Practical habits: apply on day 1 or 2, not the closing-day evening; keep the UPI app's mandate inbox clean (delete stale mandates); and make sure the UPI ID belongs to your own bank account — third-party UPI IDs are not allowed.
Rule 4: Demat must be ACTIVE and KYC clean
- Disposal Instruction (DIS) updated, no debit freezes
- KYC status verified, not "on hold" or "pending" with the KRA
- PAN linked with Aadhaar where required
An inactive or frozen demat account cannot receive the shares, so the registrar's system rejects the application.
The family strategy: the multi-account game plan
Each PAN is one lottery ticket, so a family of four with four demat accounts has four entries. Used within the rules, this is the single biggest lever retail investors control.
Minor accounts work
Minors can apply for IPOs through a guardian-operated demat account — SEBI's rules explicitly allow minors to apply in IPOs, buybacks and takeovers, though they cannot trade. Source: Zerodha support/SEBI regulations.
HUF accounts: the legitimate extra PAN
A Hindu Undivided Family can have its own PAN, bank account and demat account, adding one more application. The HUF's funds must genuinely belong to the HUF, not be your money relabelled.
Employee and shareholder quotas
Many IPOs reserve a quota for employees and sometimes for existing shareholders of the group company — these quotas are oversubscribed far less often than the retail pool. If you qualify, that application sits in a separate, easier draw.
What has changed recently
- T+3 listing: since 1 December 2023, mainboard IPOs must list within three working days of closing — bids close at 5:00 PM on T day, allotment and refunds happen on T+1, listing on T+3. Source: SEBI circular, sebi.gov.in.
- UPI limit raised to Rs 5 lakh: the UPI payment route now covers applications up to Rs 5 lakh, though the retail category itself remains capped at Rs 2 lakh. Source: NSE circular.
Final checklist
- PAN matches across bank, demat and Aadhaar
- Demat account is ACTIVE, KYC verified
- UPI ID is yours, linked to the applying bank account
- Sufficient balance in the account for the mandate block
- Category selected correctly (retail up to Rs 2 lakh)
- Cut-off price selected (retail only)
- Applied on day 1 or 2, well before the 5 PM closing-day mandate deadline
- UPI mandate approved and visible as "blocked" in the app
The arithmetic, worked out
| Distinct PANs | Entries in the pool | Chance of at least one lot (20x illustration) |
|---|---|---|
| 1 | 1 | about 5% |
| 2 | 2 | about 10% |
| 3 | 3 | about 14% |
Everything in the golden rules either protects a ticket or adds one. Here is what adding tickets looks like. Illustration: assume the retail book closes 20 times oversubscribed — the exchange prints evening updates during the window and the final ratio after close, so you are never guessing blind. One valid entry then carries roughly a 1-in-20 shot at a lot. Three genuine entries — say a working couple plus a guardian-operated minor account — work out to about 1 minus (19/20) cubed, roughly 14%.
The maths is deliberately simple and deliberately labelled: real issues run from 3x to 100x, so read these as shape-of-the-curve numbers, not predictions. What never enters the pool: extra lots from one PAN, a second bid through a second broker on the same PAN, or a bigger rupee amount inside the retail bracket. All three are the same single ticket wearing different clothes.
The sNII trade-off, stated plainly
Crossing Rs 2 lakh moves a bid out of the retail lottery and into the small-NII pool (Rs 2-10 lakh). That pool is often shallower — plenty of issues close with sNII subscribed several times over while retail runs at fifty-plus — so the per-bid odds can look tempting. What you give up matters, though: the cut-off option is gone (non-retail bidders must pick a specific price in the band, and a bid below the final price dies), and payments above the retail cap need either ASBA net banking or the raised Rs 5 lakh UPI route. Whether the trade pays depends on that issue's subscription split, which you can only watch as the window runs.
Reading the subscription split after close
Every evening of the window, the exchanges publish category-wise subscription — QIB, NII and retail. Three uses. Before your bid: a retail book running far hotter than the NII book tells you the lottery is crowded and the family-account lever matters more than usual. After close: the final retail ratio is the honest scoreboard for what your odds were — the only number that judges these tips fairly. Over a season: your own hit rate across ten issues against those published ratios. Score applications that survived validation, not allotments that landed; the first is your execution, the second is the draw.
Myths worth retiring
- "More lots, more chances." One entry per PAN in the retail draw; extra lots simply block more money.
- "Applying in the last hour skews the odds." The draw is blind to timing; late bids only raise the chance that the mandate fails.
- "Bidding above cut-off beats everyone." You cannot bid above the band's top, and cut-off already means accepting the top — there is no higher price to grab.
- "A fund that applied to the IPO gives me exposure." Funds bid from the institutional quota; you hold fund units, and you had no vote in the bid.
- "Guaranteed allotment services exist." They do not. Anything promising a certain allotment is collecting your data, your fee, or setting up a duplicate application headed for rejection.
Conclusion
One PAN, one application. Match the bank and demat PAN. Bid at cut-off as retail. Approve the UPI mandate well before 5 PM on closing day. Keep the demat active and KYC clean. Open accounts for eligible family members and an HUF if it genuinely applies. None of this guarantees allotment — oversubscription is the market's verdict — but it guarantees that every lottery ticket you paid for was actually in the draw.

Frequently asked questions
How does IPO allotment work for retail investors in India?
When the retail category is oversubscribed, the registrar conducts a computerised lottery where each valid application gets one entry per PAN. Winners receive one minimum lot; there is no partial allotment in the retail category.
Can I apply for an IPO twice with the same PAN?
No. SEBI rules permit only one application per PAN per IPO. Multiple applications — even through different brokers or bank accounts — lead to rejection of all of them.
What is the deadline to approve the UPI mandate for an IPO?
The UPI mandate must be approved by 5:00 PM on the IPO closing day. Applications where the mandate is not accepted by then are treated as cancelled, even if the broker app shows them as submitted.
Does applying at cut-off price increase my allotment chances?
For retail investors, cut-off keeps the application valid at whatever final issue price the book builds to, so a bid below the cut-off price cannot get rejected on price. That protects your lottery entry — the odds per entry stay the same.
Can I apply for an IPO from a minor's demat account?
Yes. Minors can apply for IPOs through a guardian-operated demat account, though they cannot trade shares. The application must be in the minor's own name with the guardian's details, and the minor's PAN must be unique.
