If you’ve ever opened your Demat account inside Groww and noticed a long 16-digit number labeled “BO ID,” you’re not alone. Many users see it but don’t fully understand what it actually means or why it matters.
Let’s break it down in a clear, practical way—no jargon, just what you need to know.

What is BO ID?
BO ID stands for Beneficial Owner Identification Number. It is a unique 16-digit number assigned to every investor who holds a Demat account.
Think of it like your bank account number, but for shares and securities.
When you buy stocks, mutual funds, or other securities through Groww, they are not stored inside the app itself. They are held electronically in a Demat account maintained by a depository like:
- National Securities Depository Limited (NSDL)
- Central Depository Services Limited (CDSL)
Your BO ID is your identity in this system. It tells the depository: these shares belong to you.
Structure of BO ID (Important Detail)
The BO ID is always 16 digits, but its format depends on the depository:
1. For NSDL Accounts
- Format: IN + 14 digits
- Example: IN12345678901234
2. For CDSL Accounts
- Format: 16 numeric digits
- Example: 1234567890123456
Groww typically provides Demat accounts via CDSL, so most users will see a pure 16-digit number without “IN”.
Why is BO ID Important?
This number is more important than most users realize. It’s used in multiple key processes:
1. Ownership Proof of Shares
Your BO ID confirms that you are the legal owner of the securities in your Demat account.
2. Buying & Selling Stocks
Every transaction—buy or sell—gets linked to your BO ID behind the scenes.
3. Receiving Dividends & Corporate Benefits
Dividends, bonus shares, stock splits—all are credited based on your BO ID.
4. Transferring Shares
If you ever transfer shares to another Demat account, the BO ID is required.
5. IPO Applications
When applying for IPOs, your BO ID ensures shares are allotted to your account.
Is BO ID Required for Using Groww?
Yes—absolutely.
You cannot invest in stocks without a Demat account, and without a Demat account, there is no BO ID.
Where BO ID is Required:
- Opening your Demat account (auto-generated after approval)
- Stock market investing
- IPO applications
- Share transfers
- Portfolio tracking
In short: No BO ID = No stock investing.
How to Find BO ID in Groww
Finding your BO ID in Groww is very simple. Just follow these steps:
Method 1: From the Groww App
- Open the Groww app
- Tap on your profile icon (top right corner)
- Go to “Stocks” or “Demat Account Details”
- You will see your BO ID (16-digit number)
Method 2: From Account Statement
- Open your Demat holding statement or transaction statement
- Your BO ID will be clearly mentioned at the top
Method 3: Email Confirmation
When your Demat account was opened, Groww would have sent a confirmation email. That email includes:
- DP ID
- BO ID
- Account details
BO ID vs Demat Account Number (Common Confusion)
Many users think these are different—but in most cases, they are the same thing.
- BO ID = Your Demat Account Number
- In NSDL: DP ID + Client ID combined
- In CDSL: Single 16-digit number
So if someone asks for your Demat number, you can safely give your BO ID.
BO ID vs Trading Account ID
This is another important difference:
| Feature | BO ID (Demat) | Trading ID |
| Purpose | Holds shares | Used for buying/selling |
| Issued by | Depository (NSDL/CDSL) | Broker (Groww) |
| Format | 16 digits | Alphanumeric |
Both work together, but they are not the same.
Is It Safe to Share Your BO ID?
Generally, yes—but with caution.
Safe Situations:
- IPO applications
- Share transfers
- Official financial processes
Avoid Sharing When:
- Unknown calls or messages
- Suspicious links
- Unverified platforms
Your BO ID alone cannot withdraw your shares, but it’s still part of sensitive financial data.
What If You Can’t Find Your BO ID?
If you’re unable to locate it:
- Check your email (search “Groww Demat”)
- Download account statements
- Contact Groww support directly from the app
They usually respond quickly and can guide you step-by-step.
Final Thoughts
The BO ID might look like just another random number, but it’s actually the core identity of your investments.
Every stock you buy, every dividend you receive, every IPO you apply for—it all connects back to this one number.
So take a moment to locate it, note it down safely, and understand its importance. Once you do, managing your investments on Groww becomes much clearer and more confident.
