Summary:
A Demat account number is a unique identifier used to hold and manage securities electronically in India. This guide explains how to find your Demat account number through your broker, account statements, welcome email, PAN, or the NSDL/CDSL portals. It also highlights why the number is important, common retrieval issues, and tips to keep your account details secure.
Lost track of your Demat account number? Happens to almost everyone eventually. No need to panic — it's sitting in your broker's app, an old statement, or a welcome email you probably still have. Here's where to look.
What is a Demat account number?
A Demat account number is your unique ID once you open an account with a Depository Participant, or DP. It's what lets you hold shares, bonds, and mutual funds electronically, no paperwork involved.
Two depositories issue these in India — NSDL and CDSL. NSDL numbers start with "IN" plus 14 digits, 16 characters total. CDSL numbers are just 16 digits, no letters. This number is your identity in the stock market. Every trade, every transfer, every holding traces back to it.
How to know your Demat account number?
A few places to check: your trading platform, your account statements, your welcome kit, or your depository directly. Walking through each one below.
Login to your trading platform
Fastest option. Log into Ventura's interface, go to profile or account details, and your Demat number's usually right there next to your Client ID and DP ID. Takes two minutes if you remember your password.
Check your Demat account statement
Every statement your broker sends — holdings, transactions — has your Demat number printed near the top. Look for "BO ID" or "Demat ID." If you get emailed statements, search your inbox.
Check Your Welcome Email or Account Opening Kit
When you first opened your account, your DP sent a welcome email or kit with everything, including your Demat number. Search your inbox for "welcome" or "account opening" from your broker or from NSDL/CDSL directly. Usually the fastest fix.
Check your CDSL or NSDL account
CDSL runs Easi/Easiest, NSDL runs IDeAS — both let you log in directly and view your account details. If you've registered for these, you get your Demat number and holdings without going through your broker at all.
Contact Your Depository Participant (DP)
Nothing else worked? Call your broker's support team. They'll verify your identity through PAN or registered mobile, then pull up your Demat number for you. Slower, but it always works.
How to Find Your Demat Account Number Using PAN Card
Your PAN doesn't show your Demat number directly. But every Demat account in India is linked to a PAN, so it's your way in.
Log into your broker's platform using PAN-linked credentials, or head to NSDL or CDSL's website and use their PAN lookup tool. You'll need to verify through your registered mobile or email before it shows you anything. Another option: your Consolidated Account Statement, or CAS. It lists every Demat account tied to your PAN across both NSDL and CDSL. Handy if you've got accounts scattered across multiple brokers and lost track of which is which.
Why is your Demat account number important for trading?
Every transaction you make runs through this number. Buying shares, selling them, applying for an IPO, transferring securities between accounts — none of it works without your Demat number matching correctly on the other end.
It's also how you keep track when you're holding investments across multiple brokers. During things like dematerialising old physical shares, or transmitting holdings after an investor passes away, having the right Demat number ready saves a lot of back-and-forth.
What are the common issues when retrieving your Demat account number?
Forgotten login credentials is the most common one — can't access your broker's app or NSDL/CDSL portals without your registered mobile or email for OTP. Second most common: having multiple Demat accounts across different brokers and mixing up which number belongs where.
Outdated contact details cause real trouble too. If your registered mobile or email changed and your broker doesn't have the update, OTPs and verification codes just won't reach you. Old welcome emails get deleted or buried sometimes, which is why digital search doesn't always work. When nothing else does, call your DP with your PAN and ID proof. Takes longer, but it resolves it.
Tips to Keep Your Demat Account Details Secure
Never hand over your Demat number, password, or OTP to anyone claiming to be from your broker over call or email. Real reps don't ask for your password, ever.
Keep your registered mobile and email current with your DP — they're your lifeline for verification. Don't store your Demat number in random notes or shared files. If you're spread across multiple brokers, keep a private, secure record of which number belongs where. Check your statements now and then for anything unfamiliar, and flag it to your broker immediately if something looks off.

Conclusion
Finding your Demat account number is rarely a real problem. Check your broker's app, dig up an old statement or welcome email, or use PAN through the NSDL/CDSL portal. Once you've got it, keep it stored somewhere safe — it's tied to every single trade you'll ever make.
