Learn the various options for associating your mobile phone number with your financial institution.

Learnings That Are Crucial

  • Connecting your phone number to your financial accounts is not only recommended, but required.
  • Your mobile phone number can be linked to your financial institution in a number of ways.
  • One way to link your phone number with your bank account is through online or mobile banking.
  • Going to an ATM is another option.
  • Connecting your mobile number to your bank accounts allows you to receive real-time alerts and stay on top of your finances.


Customers' phone numbers are required at the time of account opening at most banks today. They require you to link your phone number to your bank account even if you've had an account with the bank for years. The financial institution will use this number to contact you and will refer to it as your Registered Mobile Number in your account records. The bank will use the number as a safety measure to get in touch with you quickly if anything goes wrong with your account, and to notify you right away whenever you make a purchase. It's good news that a trip to the bank isn't necessary to take care of this minor formality. In this article, you'll learn how to connect your phone number to your bank account in an electronic format.

Here are the various options for connecting your mobile number to your financial institution:

With the use of your online banking portal

The simplest method of linking a mobile number to a bank account is to use the internet banking service provided by your bank. Specifically, do the following:

  1. Enter your user name and password to enter your online banking system.
  2. Find the 'contact number' tab by navigating to the "My Account" or "My Profile" section of your online banking account. Choose the account that corresponds with the mobile number you wish to associate with the account(s) you have with the same financial institution if you have more than one.
  3. Your mobile number will be linked to your bank account after you select the account and enter an additional layer of authentication, such as a password or PIN. The procedure for this varies from financial institution to institution.
  4. After the aforementioned verification steps have been taken, you will be taken to a new tab where you can enter a new mobile number or modify an existing one.
  5. You'll need to make a selection and then enter your phone number in the designated box. In order to continue, the two numbers must be the same. After entering the new number, the system may ask you to verify it in a new window.
  6. Proceed to the next step and select the "submit request" button. After providing your mobile phone number in the preceding step, the bank will send you a One-Time Password (OTP). Key in the OTP and hit the submit button.

Within twenty-four to forty-eight hours, the financial institution will have your mobile phone number associated with your account. The process of linking your phone number to your bank account is exactly the same in the mobile banking app of your bank as described above.

With your bank's automated teller machine

You can also use an automated teller machine (ATM) of your bank to connect your phone number to your account online. In a couple of minutes, you will have completed this simple procedure. Just stick to the following instructions.

  1. Go to the entrance of the nearest automated teller machine at the bank where you have an account.
  2. Just slide your ATM or debit card into the machine's appropriate slot and enter your PIN when prompted.
  3. When prompted, choose "Register Mobile Number" from the main menu.
  4. You can enter your 10-digit mobile number using the ATM keypad.
  5. After entering the mobile number, you'll be sent a one-time password (OTP) that you'll need to type in.
  6. Confirm your selection to proceed.

In the same way that online banking takes 24–48 hours to set up, mobile banking takes the same amount of time for the bank to link your phone number to your account and send you an email or text message to confirm.

Modifying a bank account's mobile phone number

Here's what you need to know to update your bank account's associated mobile phone number.

Changing one's mobile phone number through online and mobile banking

Changing the mobile number is accomplished in a manner analogous to that used during account linking. The only difference is that instead of choosing "link mobile number," you'll need to choose "update/change." The active mobile number must be entered in the appropriate field and verified (re-entered if prompted by the system). On it, you'll get a one-time password that you'll need to enter and confirm. Within a few hours, the bank will notify you that the account has been updated to reflect the new number.

Change your phone number using an automated teller machine

To change your mobile number, visit the lobby of any bank ATM. In order to update your mobile number, you'll need both the one you're currently using and the one you want to use instead. In general, nothing changes, but you will need to choose to "update mobile number" during the process. In order to proceed, you will be asked to input your current phone number and receive an OTP to that number, which you will then need to input into the appropriate tab. After entering the OTP, you'll be prompted to enter a new phone number, to which you'll be sent a new OTP. The bank will then make the necessary adjustments and send you a text message to let you know.


After reading this, you should be able to link your mobile number to your bank account online. You can also request that your mobile number be linked to your bank account by visiting a bank branch, filling out a form, and making the request there. The online options, however, are easier, faster, and more convenient.
