5 min read

Keeping your mobile number updated in your Demat account is essential for receiving transaction alerts, OTPs, and important updates from your Depository Participant (DP). If you have changed your phone number, it is important to update it in your NSDL/CDSL Demat account to ensure uninterrupted communication.

Ways to Change Your Mobile Number in a Demat Account

You can update your registered mobile number through the following methods:

1. Online Method (If Supported by Your Broker)

Most brokers provide an online facility to update contact details. Here’s how:

Step 1: Log in to your broker’s website or mobile app
Step 2: Navigate to the ‘Profile’ or ‘Account Settings’ section.
Step 3: Select the option to update contact details.
Step 4: Enter your new mobile number and authenticate using OTP.
Step 5: Confirm the request and wait for approval.

2. Updating via NSDL/CDSL Online Portals

For NSDL Accounts:

Visit the NSDL website (www.nsdl.co.in).
Go to the ‘Update Contact Details’ section.
Follow the steps to update your mobile number.

For CDSL Accounts:

Visit CDSL’s Easiest portal (www.cdslindia.com).
Log in using your BO ID (Beneficiary Owner ID).
Update your mobile number and confirm via OTP.

3. Offline Method (Through Your Depository Participant - DP)

If the online option is not available, you can update your mobile number offline:

Step 1: Visit your broker’s office or DP branch.
Step 2: Fill out a Mobile Number Update Request Form.
Step 3: Submit the form along with a self-attested copy of your PAN card and a valid ID proof.
Step 4: Your DP will verify and process the request within 24-48 hours.

Things to Keep in Mind

Ensure your new mobile number is linked to Aadhaar for seamless OTP verification.
If updating via NSDL/CDSL, use the same mobile number registered with your DP.
The update may take 1-3 business days to reflect in your account.
You may receive an SMS confirmation once the mobile number is updated successfully.

Conclusion

Updating your mobile number in a Demat account is quick and essential for staying informed about your investments. Whether through your broker’s online platform, NSDL/CDSL, or offline mode, ensure your details are always up to date.

By following these steps, investors can easily update their mobile number in their Demat account and ensure smooth transactions and timely notifications.
