How to Check Mobile Number Linked with Bank Account?

Here are the different ways on how you can check the mobile number linked with the bank account:

  • Mobile Banking App: Log into your bank's mobile banking app. Go to the profile or account section, where you may find your linked mobile number from the personal details section.
  • Internet Banking: Log into your banking profile and go to the "Profile" or "Personal Details" section. Here, you can find the linked mobile number, which is generally masked for security reasons.
  • SMS: You will receive verification SMS notifications for banking on the mobile number linked to your account.
  • ATM: Visit your bank’s ATM and insert your card. Choose options like "Mobile Registration" or "Profile Information." This may allow you to view the linked mobile number.

  • Visiting Bank Branch: You can visit your nearest bank branch with valid identification and request to check which mobile number is linked to your account.

Benefits of Linking Mobile Numbers with Bank Account

Here are the advantages of linking your mobile number with your bank account you should not miss:

  • Enhanced Security: A mobile number linked to the bank account allows you to receive instant and seamless transaction alerts and helps detect unauthorised activities easily.
  • Two-Factor Authentication: It provides an additional security layer through OTP sent to your mobile device for transaction verification to reduce the risk of fraud.
  • Real-Time Notifications: You can receive immediate updates on account activities, balance changes, and transaction confirmations, which keeps you informed at all times.
  • Convenient Access to Services: You can easily access your banking services, such as balance inquiries and mini statements you must SMS, which ultimately saves your time visiting the branch.
  • Quick Account Recovery: If you forget your online banking password, you can quickly recover it through OTP and set a new password.
  • Timely Updates: You will easily access prompt notifications regarding your new services and alter your options in maintenance schedules or banking policies at your registered mobile number.
  • Facilitates Digital Transactions: If you use mobile banking or UPI applications, you must have the same SIM inserted in your mobile. Even when using an Internet banking facility, you need OTP to authenticate the transactions.

When you think of linking your mobile number with your bank account, it is always essential to have an active one connected to your bank account. This helps you efficiently access your bank transactions, updates, offers, security notifications, etc.

If you cannot solve your problem with any of these steps due to a technical error, it is best to contact your bank’s customer support or visit your home branch.
