You generally cannot know a bank account number from a mobile number directly
Banks do not publicly provide account numbers linked to mobile numbers for privacy and security reasons
You can contact the bank’s customer service and verify your identity to ask what information they can share
If the mobile number is linked to your own bank account, check the bank’s mobile app, internet banking, or SMS alerts
Visit the bank branch with valid ID proof if you need account details
If you are trying to find someone else’s account number, you must get it from that person directly
If you only need to send money, use the mobile number through UPI or the bank’s payment app instead of the account number
If your mobile number is registered with your bank, use the bank’s official helpline or app to retrieve masked account details
Never use unofficial websites or apps claiming to reveal bank account numbers from mobile numbers
