The plain answer
Yes. You cannot apply for an IPO in India without a Demat account. The application form carries your Demat account number, the registrar credits your allotted shares to that number, and there is no second route for shares to reach you. Shares of a listed company exist in electronic form, held with a depository, and a depository credits only into an account.
The part that catches people out is timing. The account has to exist before the allotment lands, and in practice before you apply, because the form asks for the account details while you are filling it in. Opening the account after the issue closes is too late, and opening it on allotment day usually is as well.
This page covers what the account actually does in the process, where the shares sit once they arrive, and the handful of rules that decide whether the credit succeeds or fails. The application mechanics themselves live on the IPO application page, and this page is about the piece that has to be in place before any of that starts.
Why the allotment needs an account
An IPO is a purchase from the company itself rather than from another investor on an exchange. When the issue closes, the registrar to the issue works out the basis of allotment, decides who receives how many shares, and then instructs the depositories to credit those shares. That credit instruction names a Demat account number.
Put a number in the instruction that has no account behind it, or an account that cannot accept a delivery, and the credit fails. The shares stay with the registrar until a valid destination turns up, and for practical purposes your application is dead.
There is no paper alternative to fall back on. India has moved listed securities into electronic form, so a share certificate is the exception rather than the rule, and a listed company cannot allot physical certificates on request. If you own shares of a listed Indian company, you own them in a Demat account.
A salary comparison makes the logic plain. Your employer needs your bank account number before your pay can be credited, and a transfer to an account that does not exist simply bounces. The Demat account is the account your allotment is paid into.
Notice where the account number sits in the chain. It is not a preference you record somewhere for later. It travels with the application from the broker to the exchange bidding platform, then to the registrar, then to the depository. Every one of those systems passes the same number along, and the last one acts on it. A wrong digit in that chain is as fatal as a missing account, which is why the form asks you to confirm the BO ID before you submit.
What a Demat account is
A Demat account holds your shares in electronic form. Demat is short for dematerialised, meaning the paper certificate has been replaced by an electronic record. The account does not store shares in a vault. It records that a stated number of shares of a particular security belong to you.
The shares themselves sit with one of India's two depositories: NSDL, the National Securities Depository Limited, or CDSL, Central Depository Services (India) Limited. These are the record keepers at the centre of the system. You do not open an account with either of them directly.
You open it through a Depository Participant, normally shortened to DP. The DP is your point of contact: it opens the account, passes your instructions to the depository, and appears on your statements. Most stockbrokers act as DPs, which is why opening a Demat account and opening a brokerage account feel like a single activity.
Your DP decides which depository holds your account, not you. Some brokers work with NSDL, some with CDSL, and some offer both. The practical differences between the two are small, and the CDSL and NSDL comparison works through them.
Every account gets an identifier called a BO ID, short for beneficiary owner identification number. It combines the DP's code with your client number, and it is the number an IPO application asks for. If you have ever wondered what the 16 digits on your statement mean, the BO ID explainer unpacks them.
The account also does quiet work the rest of the year. Dividends arrive against the shares recorded in it. Bonus shares, splits and buybacks are applied to it automatically, because the depository knows which account holds each security on the record date. When a company merges and your shares are exchanged for the acquirer's shares, the old holding leaves the account and the new one arrives, with no action from you. None of that requires you to apply for anything or fill in a form.
That is worth pausing on, because it explains why the account is not really an IPO requirement at all. It is a holding requirement that an IPO happens to expose. You need it for the allotment because you will need it for everything the investment does afterwards.
Demat vs trading account
Brokers usually open two accounts for a new client: a Demat account and a trading account. They do different jobs, and only one of them is needed to apply for an IPO.
| Account | What it is for | Needed to apply for an IPO? |
|---|---|---|
| Demat account | Holds your shares in electronic form with a depository | Yes. The application carries its account number, and the allotment credits into it |
| Trading account | Places buy and sell orders on the exchange | No. You need it to sell the shares once they list |
| Opened together | Most brokers run one KYC and open both as a pair | Only the Demat half is compulsory for the application |
The trading account is the order window. It connects you to the exchange so you can buy and sell, and it never holds shares of its own. The Demat account is the store. Everything you own sits there: shares allotted in an IPO, shares bought on the exchange, and shares received through a bonus, a split or a merger.
So an investor with only a Demat account can apply for an IPO. What that investor cannot do is sell the shares on listing day, because a sale is an exchange order and exchange orders run through the trading account. In practice most people have both, since brokers open them as a package, and the distinction only becomes visible when a KYC for one of them is delayed.
The delay scenario is the one to watch. Brokers run a single KYC and open both accounts from it, but the two can become usable on different days. A Demat account that is open and active is enough for the application, so a pending trading account does not stop you applying. What it does stop is selling, which matters if you planned to exit on listing day.
One more shape exists: the three-in-one account, where a bank, a broker and a depository account are bundled so money moves between them without a transfer step. The Demat account inside that bundle is the same Demat account as any other, and it satisfies an IPO application in exactly the same way. The three-in-one comparison covers when the bundle is worth it.
The account has to be active
A Demat account is a live service, not a locker. The depository expects activity, and an account with none for a long stretch gets marked inactive and then dormant. A dormant account cannot receive a delivery, which means it cannot receive your allotment.
The mechanism is unglamorous. The credit instruction arrives at the depository, the system checks the account status, and a dormant account fails the check. Your shares do not vanish. They wait with the registrar while the issue moves on without you.
Frozen accounts behave the same way. An account can be frozen because of a lien, a court order, or KYC details that have gone stale. Whatever the reason, a frozen account cannot accept a credit, and the IPO application attached to it fails at the last step.
Bringing an account back to life is a separate process with your DP. It generally means submitting a fresh KYC form, and sometimes completing a small transaction to mark the account live. It is not instant, and starting it after the allotment fails costs you the issue. The dormant account page walks through the reactivation steps.
The easy habit is a login every few months plus a status check before you apply. Logging in does not always count as activity on its own, so confirm with your DP what your account needs. Ten minutes of checking is cheaper than a failed application.
Ask a specific question when you check, because "is my account active" and "can my account receive a credit" are not always the same answer. A status letter from the DP, or the account status line inside the broker app, tells you where you stand. Do this during a quiet week rather than during an issue window, since a DP's support desk moves slowly when an IPO is open and hundreds of applicants are calling about the same things.
PAN, Aadhaar and KYC
A Demat account is keyed to your PAN. Without a PAN you cannot hold one, and without a PAN linked to Aadhaar and in working order, the KYC will not clear. There is no route around this for a resident individual, and the page on accounts without PAN or Aadhaar covers the narrow exceptions that exist.
One PAN can hold more than one Demat account, and that is perfectly legal. What is not allowed is more than one IPO application per PAN per investor category in the same issue. Apply twice in the retail category and the registrar treats both applications as invalid.
That rule explains why a second Demat account does nothing for your allotment odds. Applications are matched on PAN, not on account number. Two applications under one PAN are not two chances; they are zero. The page on holding several accounts sets out where a second account genuinely helps.
Aadhaar does one specific job in this process: it verifies who you are and ties the account to a mobile number for OTPs. That Aadhaar has to be linked to a mobile you can actually reach, because the codes land there. Account opening is fully paperless and typically takes about 15 minutes with a PAN, an Aadhaar linked to a mobile number, bank details and a signature. The account becomes usable once the KYC verification clears, and the account opening timeline covers what happens in that gap.
Whose name, and whose money
Two rules about names and money govern every IPO application, and breaking either one gets the application rejected after the issue closes, usually without a warning you can act on.
The first rule: the Demat account has to be in the applicant's own name. Not a parent's, not a spouse's, not the family account that everyone shares. A joint Demat account credits to the first holder, so an application from a joint account has to run in the first holder's name.
The second rule: the bank account behind the ASBA block has to belong to the applicant too. ASBA does not permit third-party funding. You cannot apply in your own name and have a relative's bank account provide the money for the block.
Read the two together and you get the matching test the registrar runs. The PAN on the application, the PAN on the Demat account and the PAN on the bank account must all belong to the same person. A mismatch anywhere in that chain is one of the most common reasons an application fails even though the UPI mandate was approved and the money was blocked on time.
The UPI ID sits in the same chain and gets less attention than it deserves. The mandate is raised against the bank account behind that UPI ID, so the account has to be yours. A UPI ID linked to a joint account, or to an account where you are a second holder, is a mismatch waiting to happen. Use a UPI ID that maps to an account in your name alone, and check it before the issue opens rather than while the window is running.
The full sequence
- Open the Demat account and finish KYC
- Apply in the broker app with your UPI ID
- Approve the mandate: the bank blocks the cap price
- T+1: the registrar finalises the basis of allotment
- T+2: allotted shares credit to the Demat account
- T+3: the shares list and you can sell them
The first step on that diagram is the only one you have to plan around. Everything below it runs on a fixed clock set by the regulator, and you cannot speed it up or slow it down.
Under SEBI circular SEBI/HO/CFD/TPD1/CIR/P/2023/140 of 9 August 2023, an issue closing on T day has its basis of allotment finalised on T+1, sees shares credited and failed applications unblocked on T+2, and lists on T+3. So the Demat account has to be ready before T+2 at the very latest, and because the application form carries the account number, it has to be ready before you apply.
The money does not move at application. ASBA stands for Application Supported by Blocked Amount, and the bank blocks the application amount at the cap price of the band, which is the top of the price range. If the issue prices lower than the cap, the difference releases. If you are not allotted, the whole block releases. Either way the money stayed in your account and kept earning whatever interest your bank pays.
- The retail cap. A retail individual application tops out at ₹2,00,000 per PAN, and the category allows one application per PAN. Larger bids move into the non-institutional category with different allocation rules.
- The UPI ceiling. The UPI mandate route handles blocks up to ₹5 lakh per application. Above that, the bank ASBA route through net banking takes over as the blocking mechanism.
- The block runs at the cap. The final issue price is set after the book closes, so the system holds the worst case up front. The block is a cash requirement, not a price prediction.
On T+2 the shares arrive in the same Demat account the application named, and they appear in the holdings list the way any other share does. There is no separate IPO section to check and no certificate to collect. If you want to confirm the credit independently, the monthly consolidated account statement from the depository lists every holding across every Demat account linked to your PAN, and the broker app usually updates on the same day. The guide to reading your CAS shows where the entry appears.
If you are not allotted, nothing arrives and there is nothing to fix. The block releases, the money is available again, and the application does not carry forward to the next issue. Each IPO starts with a fresh application, a fresh mandate and a fresh look at whether the account details on file are still current.
What it costs
Opening a Demat account carries no fee at the brokers compared on this site. DematOpen's own records show ₹0 to open an account and ₹0 brokerage on an IPO application, so the account itself adds nothing to the cost of applying. There is no commission layer between your bid and the exchange.
The charge that does exist over time is the annual maintenance charge, usually called AMC, which is the fee for keeping the account open. That is a running cost of holding the account rather than a cost of the IPO, and it applies whether or not you ever apply for an issue. The charges page breaks down what AMC covers and how brokers price it.
On the application side, the only money involved is the block itself. It is your money, sitting in your bank account under a lien, and it returns whole if you are not allotted. There is no application fee, no processing charge and no enquiry fee along the way.
So the honest answer to what the Demat account costs you for an IPO is nothing at application. The account has a running cost over years, and the IPO application you make with it does not.
The charges that do appear later arrive on the sell side, not the apply side. When you eventually sell the allotted shares, the contract note carries brokerage, statutory charges and the depository charge that applies per scrip per day. None of those attach to the application, the allotment or the credit. The DP charge explainer covers what that line on the contract note means.
Minors, NRIs and companies
Everything above describes a resident individual applying in their own name, which is the shape of most retail applications. Four groups sit outside that shape, and the account they need changes with them.
| Applicant | Account type | What changes |
|---|---|---|
| Minor | Minor Demat account, operated by a guardian | A guardian applies on the minor's behalf. No trading in F&O or intraday. The account converts to a regular one when the minor turns 18. |
| NRI | NRI Demat account, PIS or non-PIS route | The route depends on the bank and on whether you intend to repatriate the sale proceeds. Documentation and rules differ between the two. |
| HUF | HUF Demat account | The account uses the HUF's own PAN, and the karta operates it. |
| Company, partnership or trust | Non-individual Demat account | Extra documents: incorporation or registration proof, a board resolution or the deed, and a list of authorised signatories. |
The minor account has one detail that catches parents. The account is in the minor's name from the day it opens, with the guardian operating it, and the shares belong to the minor. When the minor turns 18, the account converts into a regular one and the KYC has to be redone in the minor's own name. A parent applying through a minor's account is applying in the minor's name, which means the PAN on the application is the minor's PAN. The minor account page covers the guardian documents in full.
The NRI case varies the most, because the right route depends on your bank, your residency status and where you want the proceeds to end up. Repatriating sale proceeds and keeping them in India lead to different account structures. Confirm the route with your broker before you open anything, rather than after.
Under both routes one thing stays constant: the account is in your own name, keyed to your own PAN, and the bank account behind the block is yours. An NRI applying with an NRO account can fund the block from that account and receive the sale proceeds back into it. Whether the proceeds can then leave the country is a separate question with a separate answer, and it belongs to your bank rather than to the IPO.
For entities the account belongs to the entity, not to the person signing the form. A company needs a board resolution naming the authorised signatory. A partnership needs the deed. A trust needs the trust deed and a trustees' resolution. The application then runs in the entity's name, and the same one-application rule applies per entity PAN, per category.
What people usually get wrong
I can apply now and open the Demat account before the shares land
The application form carries the Demat account details, so there is nothing complete to submit without an account. Even a submitted application fails, because a credit to a missing account does not go through at T+2.
A trading account is what an IPO application needs
The allotment credits to the Demat account. The trading account is what you need later, to place the sell order once the shares list on the exchange.
I can apply with a relative's Demat account and my own bank account
The Demat account and the bank account must both belong to the applicant, and the PAN on each has to match the PAN on the application. ASBA does not permit third-party funding.
A dormant account is fine as long as I know the account number
A dormant, inactive or frozen account cannot receive a credit. Reactivating it is a separate process with your Depository Participant, and it is not instant.
The Demat account I choose affects my allotment chances
Allotment runs on the application, not on the account. The registrar matches applications on PAN, and one application per PAN per category is all that counts.
Questions people ask
Yes. Allotted shares are credited to a Demat account number, so the registrar needs one to complete the allotment. The application form carries those account details, which means the account has to exist before you apply, not merely before the shares arrive.
Not for the same issue. The application form asks for the Demat account number as you fill it in, so there is nothing complete to submit without one. Opening the account afterwards means sitting out that issue and applying in the next one.
No. The allotment credits to the Demat account, and the Demat account is the only one an application needs. A trading account is what you use to place the sell order once the shares list on the exchange.
Whichever account you named on the application. Only one application per PAN per investor category is valid for a single issue, so a second Demat account does not let you apply twice and does not change your allotment odds.
It matters completely. The account has to be in the applicant's own name, and the bank account behind the ASBA block has to be the applicant's own as well. Third-party funding is not permitted, and a joint account credits to the first holder, so the application must run in the first holder's name.
Only once it is active again. A dormant or inactive account fails the allotment credit, and reactivating it is a separate process with your Depository Participant that does not finish instantly. Check the account status before you apply, not after the allotment fails.
Where to go next
The Demat account is the gate, and once you are through it the application runs on a fixed schedule you cannot influence. These pages carry the rest of the route:
