If you’ve tried more than one broker for investing, trading, or IPOs, you may have opened multiple demat accounts over time. Many people notice this only when annual charges get deducted, or when they’re unsure which demat account is linked while applying for an IPO. The quickest way to check is to download your latest Consolidated Account Statement (CAS), it often shows all demat accounts linked to your PAN in one place. If anything is missing, you can cross-check using broker CMRs and depository alerts.

In this guide, you’ll learn how to check how many demat accounts are registered in your name, the fastest ways to verify them, and what to do if you find old or unused accounts.

How to check how many accounts you have?

It means identifying every demat account opened in your name, including those you don’t actively use today.

The easiest way is to use your Consolidated Account Statement (CAS) because it often shows multiple demat IDs linked to your PAN in one place.

You can then cross-check with broker apps/CMR and CDSL/NSDL alerts to make sure you haven’t missed an old or unused account.

Ways to Check All Your Demat Accounts

There isn’t a single universal dashboard that shows all demat accounts ever opened. Instead, the system already generates records that help you list and count them. Use these methods in order.

1) Use your Consolidated Account Statement (CAS) to count demat accounts

Your Consolidated Account Statement (CAS) brings together information linked to your PAN and shows your securities holdings and transactions in one statement. CAS is built to help investors see their holdings and transactions without tracking each broker separately.

How to use CAS to count accounts?

Find your latest CAS (in email) or download it from the official CAS facility (based on your depository setup).
Open the PDF (it may be password-protected).
Look for separate demat account sections or identifiers.
Note each unique demat account number shown.
Count how many unique demat accounts appear.

How often do you receive CAS?

If there are transactions during a month, investors typically receive CAS monthly.
If there are no transactions, it is usually sent less frequently (often half-yearly).

2) Search your SMS and email for CDSL/NSDL alerts (fast discovery method)

Even if you can’t find CAS right away, alerts can give you quick clues about extra accounts.

Search these keywords in your SMS inbox

“CDSL”
“NSDL”
“BO ID”
“demat debit”
“demat credit”
“DP”

What to search for in the email?

“CAS”
“CDSL”
“NSDL”
“Demat”
“Transaction statement”
“Client master”
Broker names you may have used

If you find messages referencing different demat identifiers, it usually means you have more than one demat account.

3) Check each broker’s account details or Client Master Report (CMR)

CMR (Client Master Report) is a document from your broker/DP that shows your demat account details like your name, DP ID/BO ID, and bank-linked information.

If you think you’ve opened accounts with more than one broker, the next step is to list them one by one. For each broker/DP you’ve used, note:

Broker/DP name
Depository (CDSL or NSDL)
Demat account number
Status (active/closed/unsure)
Registered email and mobile

How to recognise the demat number?

CDSL: usually a 16-digit BO ID (Beneficiary Owner Identification Number)
NSDL: usually DP ID (often starts with “IN”) + Client ID

This list becomes your personal “demat inventory” so you don’t lose track again.

4) Use depository portals to verify holdings (for accounts you already know)

You can check your accounts in CDSL or NSDL what shares are held in that demat account and download transaction statements.

For CDSL accounts: Use CDSL’s investor portal (Easi/Easiest). After you register using your BO ID and basic details, you can see your holdings, recent debits/credits of shares, and statement history.
For NSDL accounts: Use NSDL’s IDeAS facility. Once registered with your DP ID and Client ID, you can view your holdings and transactions in that NSDL demat account and download statements.

These portals are especially useful when you’ve forgotten which broker app you used, or when you want to double-check holdings before closing an account.

5) If you’re still unsure, confirm with the DP (broker support)

Sometimes you’ll find an old welcome email or a demat number in your inbox, but you can’t access the broker app anymore. In these cases, the quickest way is to contact the DP and ask them to confirm the account status.

When you reach out, ask for these details:

Demat account number (BO ID for CDSL / DP ID + Client ID for NSDL)
Depository (CDSL or NSDL)
Status (active, closed, or inactive)
Holdings/pledges/holds
Closure process (documents needed and expected steps)

Real case example:

Meera used three brokers over five years (investing, trading, and IPOs).

To check how many demat accounts she has, she finds her CAS in her email and spots three different demat IDs (two CDSL BO IDs and one NSDL DP + Client ID).

She cross-checks SMS alerts and downloads CMRs from the broker apps to record the account details.

Result: She confirms 3 demat accounts and plans to close the unused one after checking that there are no holdings or dues.

Benefits of Checking All Your Demat Accounts

One place to start (CAS): CAS helps you spot multiple demat accounts linked to you without checking every broker first.
Works even if you forgot old logins: You can still identify accounts using statements and alerts, even if you don’t remember every broker app.
Clear identification: Every demat account has a unique ID (CDSL BO ID or NSDL DP + Client ID), so you can count and track them accurately.
Avoid extra charges: Once you find unused accounts, you can decide whether to close them after confirming zero holdings and dues.
Fewer mistakes in IPOs and actions: Knowing the correct demat account reduces errors when applying for IPOs, pledging, or handling corporate actions.
Better records and safety: It becomes easier to track statements, taxes, and also notice unexpected alerts early.

Risks, Limitations, and Common Mistakes to Avoid

Mixing up trading vs demat: Your trading login is not your demat account. The demat account has a separate ID (CDSL BO ID or NSDL DP + Client ID).
Assuming unused means closed: Stopping usage doesn’t close the account. It usually stays active until you submit a closure request.
Missing accounts due to old contact details: If your email/mobile wasn’t updated with the broker/DP, you may not receive CAS or SMS alerts even though the account still exists.
Overlooking joint accounts: Joint demat accounts are easy to miss, especially if you’re the second holder.
Forgetting IPO-only accounts: Accounts opened just for IPO applications often get left behind and later create confusion.
Ignoring small yearly deductions: AMC or DP charges can be the only sign an old account is still active.
Getting stuck due to forgotten logins: If you can’t access an old broker app, you’ll need DP support to confirm the demat number and status.
Falling for fake links: Scammers copy depository-style messages. Use the broker’s official app or type the website yourself instead of clicking random links.

Knowing how many demat accounts you have is less about curiosity and more about control. It helps you avoid scattered holdings, surprise charges, and confusion when you need the right demat details for an IPO, a pledge, or a sell order. Once you’ve mapped your accounts, you can keep things organised, either by sticking to one main account or clearly separating accounts by purpose (long-term investing vs short-term trading).
