How to block bank account online

You can block your bank account online through various digital channels provided by your bank to prevent unauthorized transactions. Most Indian banks offer a "Kill Switch" or emergency blocking feature. Common methods include:

• Mobile Banking App: Log in and look for security settings or "Quick Links" to temporarily block the account or specific services like UPI and net banking.
• Internet Banking: Navigate to the profile or security section to disable your user ID or restrict account access.
• SMS Service: Many banks allow blocking by sending a specific keyword to their official number from your registered mobile.
