Common Reasons for Non-Allotment of Shares in an IPO

    Summary:


    Not receiving IPO shares is often less about doing something wrong and more about heavy demand. When an issue is oversubscribed, shares are usually allotted through a lottery process. Allotment can also fail because of small but important issues such as incorrect application details, bidding below the final issue price in book built IPOs, PAN or bank detail mismatches, or insufficient funds in the linked account. Careful form filling and accurate bidding can improve the likelihood of allotment.

    One of the exciting things that can happen on the stock market is an Initial Public Offering (IPO). It's the time when a private company goes public and sells its shares for the first time.

    For investors, the appeal is obvious: a chance to get in on the ground floor of what could be the next big thing. Everyone wants early access.

    The application itself looks simple. You fill out a form online. The company decides. But that simplicity is deceptive.

    Getting an allotment, especially in a popular IPO, is far from guaranteed. Many small things can go wrong and lead to disappointment.

    Understanding why applications get rejected is the key to improving your own odds. Let's break down the common hurdles and the smart ways to clear them.

    What is an IPO Lot?

    It's important to understand that you don't apply for individual shares in an IPO. You apply for a "lot." Think of it as buying in a pre-set bundle.

    The company decides the minimum number of shares that make up one lot. Every application you make must be in multiples of that lot size.

    The company might, for instance, set the price at ₹100 per share and the lot size at 145 shares. This means that you have to apply for at least 145 shares.

    You have to apply for 2 lots (290 shares), 3 lots (435 shares), and so on if you want to apply for more. You can't ask for a random number, like 200 shares.

    Most Common Reasons Behind Not Receiving an IPO Allotment

    It is significant to understand why an IPO is not allocated, since this could either arise from large oversubscription or a faulty application. Investors have no control over either the level of subscription or the allotment process, which relies on lottery-based methods. However, they can limit the chance of rejection of their applications if they check all details correctly and thoroughly.

    IPO Oversubscription and Allocation Process

    In a perfect world, a company would issue just enough shares for everyone who wants them. If they needed 10 lakh applicants, 10 lakh people would apply, and everyone would be happy.

    But that's not how it works. A hot IPO is like a sold-out concert with only a handful of tickets. It might get applications for 5, 10, or even 100 times the shares it's actually offering.

    This is called oversubscription. It’s a big reason why getting an allotment is so difficult. There simply isn't enough to go around.

    When this happens, the game changes from "first come, first served" to a game of chance, where your odds of success drop dramatically.

    Computerised Allotment System

    So what happens when an IPO is massively oversubscribed? The allotment process turns into a digital lottery. There’s no human picking names out of a hat.

    A computerised system is used to ensure the process is fair and unbiased. It randomly selects the lucky applicants from the massive pool of eligible entries.

    While this system gives everyone an equal shot, it's still a lottery. Because so many people want a small number of shares, many people who apply will not get any.

    Errors in the Application Form

    This is one of the painful reasons to miss out because it's usually avoidable. IPO applications are scanned by software, and even a tiny mistake can get your form thrown out.

    • Multiple applications: Submitting multiple applications from one PAN number. The system is built to catch this, and it will automatically reject all of them. No exceptions.

    • Mistakes: A typo in your name. A single wrong digit in your PAN number. Small details that have big consequences.

    • Name Mismatch: Another common tripwire is a name mismatch. The name on your application must be identical to the name on your PAN card and your linked bank account.

    • Bid Price Below the Final Price: Many IPOs today are book-building issues. This means there's a price range, and you place a bid within it. The final price is decided later, based on demand.

    Here's the rule: if your bid is even one paisa below that final issue price, your application is out of the running. It won't even be considered for the lottery.

    This is why just bidding any amount within the range is a risky move. If you bid low to save a few rupees, you might end up with nothing at all.
