The worry is missing an apparently certain listing gain because everybody else is applying. That pressure can turn a straightforward application into a poor investment. Keep one rule: decide whether you want the business before deciding how many lots to request. A popular issue can still be expensive, and its shares can list below the offer price.
What you need before applying for an IPO
You need an eligible demat account, PAN and a suitable bank account with sufficient available funds. If using UPI, check the supported bank, app and ID, and use your own eligible payment details. Make sure the applicant information matches the demat record. Our demat-account guide explains the account basics.
Read the offer document and issue information on the exchange or issuer’s official channels. Check how the company earns, its risks, debt, use of proceeds and whether existing shareholders are selling. The equity and investment banking guide explains why advisers help market an issue and why their involvement is not a promise of your return.
Lot size and blocked money: a worked example
| Fictional mainboard issue | Example | What it means |
|---|---|---|
| Price band | ₹190 to ₹200 a share | The final issue price is set through the issue process |
| Lot size | 75 shares | Bids must follow the specified lot multiple |
| One lot at the upper price | 75 × ₹200 = ₹15,000 | Amount to keep available for this bid |
| Two lots at the upper price | 150 × ₹200 = ₹30,000 | More money blocked, no guaranteed allotment |
| One lot allotted at ₹198 | 75 × ₹198 = ₹14,850 | Only the allotted-share amount is debited |
The figures describe a fictional issue, not a live recommendation. If ₹30,000 was blocked and only one lot was allotted at ₹198, ₹14,850 would be debited and ₹15,150 unblocked. If nothing was allotted, the full block would be released. Because the original money was blocked rather than paid out, the release is not always shown as a new refund credit.
For ordinary mainboard issues, the retail individual category generally covers bids up to ₹2 lakh. The UPI payment limit is a separate concept and must not be confused with the retail category boundary. Follow the specific offer document and your application flow. SME issues have different conditions, minimum application requirements and risks; do not apply this mainboard example to them automatically.
Apply through ASBA or an eligible UPI flow
With bank ASBA, select the issue in your bank’s investment or IPO service, enter the applicant and demat details, choose the category, quantity and bid price, and authorise the application. The bank blocks the required amount. NSE’s ASBA explanation describes verification, blocking, allotment debit and release of unused funds.
With an eligible intermediary’s UPI flow, enter the bid and your supported UPI ID. A block mandate should arrive in your payment app. Check the issue name, amount and mandate details against your application before approving it. NPCI’s IPO-on-UPI guide describes this block-mandate process.
A mandate approval requires your UPI PIN inside the trusted app, but nobody should ask you to reveal that PIN. Do not approve an ordinary transfer to a recruiter, agent or unfamiliar personal UPI ID claiming to reserve shares. Retain the application number and verify both the bid status and the successful fund block.
For a book-built issue, eligible retail bidders may have a cut-off option, meaning they agree to the final discovered issue price within the band. Read the application instructions rather than assuming every category has that option. Apply ahead of the closing window so a missing mandate or data error can be addressed in time.
Allotment and listing are separate stages
After bidding closes, the issue’s allotment process determines whether you receive shares and how many. In a heavily oversubscribed retail category, a draw may be needed to allocate minimum lots. Applying for more lots does not automatically multiply your chance of receiving a lot. Multiple ordinary applications under the same PAN can create rejection problems; follow the issue’s category-specific rules.
Check allotment through the official registrar or exchange route, not a random message link. Review your bank block and demat credit against the published timetable. If funds remain blocked beyond the expected process, contact the bank or intermediary with the application and mandate references. Do not pay someone a fee to release them.
A practical timeline and mistake checklist
- Before opening: read the offer document, decide whether the risk fits you and set an affordable maximum amount.
- During bidding: check the lot size, category, PAN and demat details, then authorise the correct block and verify status.
- After closing: follow the issue’s published allotment, debit, unblocking and demat-credit dates. They are issue-specific.
- Before listing: decide how the holding fits your investment plan. Do not improvise solely from a chat group’s prediction.
- After listing: keep allotment and contract records for costs and future tax reporting. The beginner share-buying guide explains the next stage.
What to do next
- Read the official offer document and set an affordable bid limit.
- Submit correct details and verify the ASBA or UPI fund block.
- Track official allotment and listing dates, keeping all references.
