Losing track of your demat account number is more common than most investors admit, especially if you’ve opened accounts with more than one broker over the years or haven’t logged in for months. The good news: your PAN card is the single thread connecting every demat account you own, and this guide walks through exactly how to use it to recover that 16-digit number, whether you’re filing taxes, consolidating scattered holdings, or simply confirming which accounts are actually active under your name.
What a Demat Account Number Actually Looks Like
Before hunting for your number, it helps to know what you’re actually looking for, since NSDL and CDSL format theirs differently.
- NSDL accounts display a 16-character code starting with “IN,” followed by 14 digits — this is your DP ID combined with your Client ID
- CDSL accounts use a straightforward 16-digit numeric code, often called the BO ID (Beneficiary Owner ID)
- Most brokers today are CDSL-affiliated, though several full-service brokers and banks still route through NSDL
- Statements and contract notes frequently show a masked version of this number for security, which is exactly why knowing how to retrieve the full number through your PAN matters
- PAN linkage is mandatory for every demat account under SEBI regulations, which is precisely why it works as your recovery key
Method 1: Check Your Broker’s Website or App
This is genuinely the fastest route for most people, since your demat number is stored right inside your trading account profile.
- Log in to your broker’s app or website using your PAN-linked credentials
- Navigate to the “Profile,” “Account Details,” or “Settings” section
- Your Demat/BO ID is typically displayed alongside your trading account details, without needing to search further
- Most apps surface this within a couple of minutes of logging in, making it the quickest option if you only have one active broker
Method 2: Search Your Email for the Welcome Letter
When your Depository Participant (DP) first activated your account, they sent a confirmation with all the essential details attached.
- Search your registered email inbox for the welcome email or SMS sent by your DP at account opening
- This communication almost always includes your full demat account number, Client ID, and DP ID
- If you can’t locate it, check your spam or promotions folder, since these automated emails sometimes land there
- This method works well even if you’ve forgotten your broker login, since email search doesn’t require account access
Method 3: Use the CDSL or NSDL Portal Directly
Both depositories run their own portals specifically built for account holders to check and manage their holdings.
- Visit CDSL’s Easi/Easiest portal or NSDL’s IDeAS portal, depending on which depository your broker uses
- Register or log in using your PAN, along with supporting verification like your date of birth or registered mobile number
- Once verified, the portal displays your linked demat account details, including the account number
- This method is particularly useful if you want to check every demat account registered under your PAN, not just one broker’s, since it isn’t tied to a single brokerage relationship
Method 4: Check Your CAS (Consolidated Account Statement)
If you’ve ever opened more than one demat account, this is genuinely the most complete method available.
- NSDL and CDSL jointly issue a Consolidated Account Statement every month (or quarterly, if there’s no transaction) to your registered email
- The CAS lists every demat account linked to your PAN across brokers, along with each account’s full number and current holdings
- This is the single best way to confirm whether you have dormant or forgotten accounts you’re not actively using
- Search your email for “CAS” or “Consolidated Account Statement” from NSDL or CDSL if you can’t immediately find it
Method 5: Contact Your Broker or DP Directly
When digital methods don’t turn up an answer, a direct call still works reliably.
- Reach out to your broker’s or DP’s customer care through phone, email, or in-app chat
- Be ready to verify your identity with your PAN, registered mobile number, and other basic KYC details
- Once verified, the support team can retrieve and share your demat account number directly
- This typically takes longer than the app or portal route, sometimes up to a day, so treat it as a backup rather than the first option
A Word on Security
Your demat account number, combined with your PAN, is sensitive financial information, and phishing attempts targeting investors have risen noticeably in recent years.
- Only use official broker apps, or CDSL and NSDL’s own portals — never a third-party website claiming to “look up” your demat number using just your PAN
- Enable two-factor authentication wherever it’s offered, both on your broker account and depository portal logins
- Never share your PAN, demat number, or OTPs with anyone claiming to be from your broker over an unsolicited call or message
- Genuine broker or DP support will never ask for your account password or OTP to “verify” your identity
FAQs
Q1. Can someone else find my demat account number just by knowing my PAN?
No — PAN alone isn’t enough for a third party to pull up your demat details. Retrieval always requires additional verification, like your registered mobile number, date of birth, or OTP access, through your broker’s app or the official CDSL/NSDL portal.
Q2. I have accounts with two different brokers. Will the CAS show both?
Yes. Since your PAN links every demat account you hold, the Consolidated Account Statement from NSDL or CDSL lists all accounts registered under that PAN, regardless of which broker or bank opened them.
Q3. What’s the difference between my Client ID and my demat account number?
For CDSL accounts, the 16-digit BO ID is your complete demat account number. For NSDL accounts, the number is your DP ID combined with your Client ID, which together form the full 16-character code.
Q4. I switched brokers a few years ago — could I still have an old, unused demat account?
Quite possibly. Checking your CAS or logging into the CDSL/NSDL portal directly with your PAN is the most reliable way to surface any dormant accounts you may have forgotten about, since these aren’t tied to just your current broker relationship.
