A new IPO is announced, your friends are discussing the grey market and you want to try for an allotment. But how does the process actually work? If you are wondering how to apply for IPO in India, the good news is that SEBI’s rules have made it simpler, faster and safer than it was a decade ago. Your money is never debited unless you get shares.
This guide covers the full journey: the documents you need, UPI and ASBA methods, investor categories, lot size maths, how allotment works, when funds get unblocked and what happens on listing day.
Key takeaways
- You need a PAN, a demat account and a bank account linked to UPI or enabled for ASBA net banking.
- Under ASBA, money is only blocked in your account, not debited, until allotment is finalised.
- Individual investors can apply through UPI for bids up to ₹5 lakh per application, as per SEBI’s framework. Larger bids use ASBA through net banking or a bank branch.
- The retail individual category covers applications up to ₹2 lakh. Above that you fall into the non-institutional (HNI) category.
- SEBI has made the T+3 timeline mandatory for mainboard IPOs since December 2023: shares are listed within three working days of the issue closing.
What you need before applying for an IPO
- PAN card: Mandatory. One PAN can make only one application per category in an IPO. Multiple applications from the same PAN are rejected.
- Demat account: Shares are credited here. The PAN on the demat account must match the PAN on the application.
- Bank account with UPI or ASBA: The UPI ID or bank account should belong to the applicant. Third-party UPI IDs lead to rejection.
- Offer documents: The Red Herring Prospectus (RHP), filed with SEBI and available on SEBI and exchange websites, explains the business, risks, financials and objects of the issue.
IPO investor categories: retail, HNI and others
Every IPO divides the shares on offer into reservation categories. The exact percentages are disclosed in the RHP and can differ from issue to issue, so always check the offer document.
| Category | Who can apply | Application size | How allotment usually works |
|---|---|---|---|
| Retail Individual Investor (RII) | Resident individuals, HUFs, NRIs | Up to ₹2 lakh | If oversubscribed, a lottery gives at least one minimum lot to as many applicants as possible |
| Small NII (sHNI) | Individuals, HUFs, companies, trusts | Above ₹2 lakh up to ₹10 lakh | Draw of lots for a minimum application size |
| Big NII (bHNI) | Same as above | Above ₹10 lakh | Draw of lots for a minimum application size |
| QIB | Mutual funds, insurers, banks, FPIs | Large institutional bids | Proportionate or as per offer document |
| Employee / Shareholder quota | Eligible employees or existing shareholders | As per RHP | As per RHP |
Note that SEBI periodically reviews these frameworks, including the retail share in very large issues. Treat the RHP of each IPO as the final word.
How lot size and price band work
In a book-built IPO, the company announces a price band and a lot size (minimum number of shares). You must bid in multiples of the lot.
Worked example: An IPO has a price band of ₹285 to ₹300 and a lot size of 50 shares. One lot at the upper band costs 50 × ₹300 = ₹15,000. A retail investor can apply for up to ₹2 lakh, so the maximum is 13 lots (13 × ₹15,000 = ₹1,95,000). Fourteen lots would cost ₹2,10,000 and cross the retail limit.
Retail investors can tick the cut-off price option, which means you agree to buy at whatever final price is discovered within the band. The amount blocked is calculated at the upper end of the band, and any difference is released after allotment.
How to apply for IPO in India through UPI: step by step
Most retail investors now apply through their broker’s app using UPI. The flow looks like this:
- Step 1: Check open and upcoming issues, dates, price band and lot size on the Quantsgrow upcoming IPO tracker.
- Step 2: Read the RHP, especially risk factors, financials and objects of the issue.
- Step 3: Open the IPO section in your broker app, select the issue and your category.
- Step 4: Enter the number of lots and bid price, or select cut-off price.
- Step 5: Enter your own UPI ID and submit.
- Step 6: Open your UPI app and approve the mandate. Your bid is not complete until you accept it. The money is blocked, not debited.
- Step 7: Check bid status in your broker app. Mandates must be approved before the cut-off time on the issue closing day.
Applying through ASBA net banking
ASBA stands for Application Supported by Blocked Amount. Log in to your bank’s net banking, go to the IPO or ASBA section, choose the issue, enter your demat details and bid. The bank blocks the amount directly. This route is common for bids above the UPI limit. Only banks listed by SEBI as Self-Certified Syndicate Banks (SCSBs) offer ASBA.
IPO timeline: allotment, refund and listing under T+3
SEBI cut the listing timeline from six working days to three. It became mandatory for issues from December 2023. If the issue closes on day T, the general sequence is:
| Day | What happens |
|---|---|
| T | Issue closes; UPI mandates must be approved by the cut-off time |
| T+1 | Basis of allotment is finalised by the registrar |
| T+2 | Shares credited to demat of successful applicants; funds unblocked for others |
| T+3 | Shares list and begin trading on NSE and BSE |
These are working days, so a market holiday in between shifts the dates. Keep the NSE holiday calendar 2026 in mind, and read our post on how NSE holidays affect settlement.
How to check IPO allotment status
Once allotment is finalised, you can check status on the registrar’s website (the RHP names the registrar) or on the NSE and BSE allotment status pages using your PAN or application number. Many brokers also show it in-app. If you are allotted, the blocked amount for those shares is debited and the rest released. If not, the full amount is unblocked.
What happens on listing day
On listing day, the exchanges run a special pre-open call auction session for the newly listed stock to discover an opening price. Normal trading starts after that session. The listing price can be above or below the issue price; there is no guarantee either way.
Newly listed stocks often show up among the top gainers today or losers because of sharp price discovery. After listing, you can follow the stock’s price and fundamentals on the Quantsgrow stocks page. Gains or losses on sale are taxed as capital gains under the rules notified by the Income Tax Department, depending on your holding period.
Common IPO application mistakes to avoid
- Not approving the UPI mandate before the deadline. The bid simply lapses.
- Using someone else’s UPI ID or bank account. The application is rejected.
- Multiple applications with the same PAN in the same category. All may be rejected.
- Applying for more than ₹2 lakh in the retail category. It can be treated as invalid or moved out of the retail category.
- Relying only on grey market premium. GMP is unofficial and unregulated. It is not a reliable indicator of listing price or business quality.
- Skipping the RHP. Look at debt, related-party transactions, promoter holding after the issue and how much of the issue is an offer for sale. Our guide on how to read quarterly results helps you judge the numbers.
An IPO allotment is a lottery ticket only in the sense of who gets shares. Whether the business is worth owning is a separate question that the RHP helps you answer.
Conclusion
Now you know how to apply for IPO in India from start to finish: get your PAN, demat and UPI ready, understand your category and lot size, approve the mandate on time, and track allotment and listing under the T+3 timeline. After listing, a stock behaves like any other share, so follow your normal research process. Our pre-market checklist is a good habit for listing day too.

Frequently Asked Questions
What is the minimum amount needed to apply for an IPO in India?
The minimum amount is the cost of one lot at the price you bid, usually the upper end of the price band. For example, if the lot size is 50 shares and the upper band is ₹300, one lot costs ₹15,000. SEBI rules set a minimum application value range for mainboard IPOs, and the exact lot size is disclosed in each issue’s RHP and price band announcement.
What is the UPI limit for IPO applications?
Under SEBI’s framework, individual investors can use UPI to bid up to ₹5 lakh per application. This covers all retail applications, which are capped at ₹2 lakh, and part of the small HNI category. For bids above ₹5 lakh, investors apply through ASBA via net banking or a bank branch. Check SEBI and NPCI updates for any change to this limit.
Is money debited when I apply for an IPO?
No. Under ASBA, including UPI-based applications, the bid amount is only blocked in your bank account. It continues to earn savings interest as per your bank’s terms. If you are allotted shares, only the amount for allotted shares is debited. If you are not allotted, the full amount is unblocked, generally by T+2 under the current timeline.
How is IPO allotment decided for retail investors?
If the retail portion is oversubscribed, the registrar uses a computerised lottery so that the maximum number of retail applicants get at least one minimum lot. This means applying for more lots does not significantly improve your chance of getting one lot in a heavily oversubscribed issue. If the portion is undersubscribed, applicants usually receive the full number of shares they applied for.
When do IPO shares list after the issue closes?
SEBI made the T+3 listing timeline mandatory for mainboard IPOs from December 2023. If the issue closes on day T, allotment is finalised on T+1, shares are credited and funds unblocked on T+2, and trading starts on T+3. These are working days, so stock market holidays in between can shift the listing date by a day or more.
