Fill the mobile number update form with valid information
Attach the self-attested photocopy of your photo ID and a passport-sized photo. Carry original documents as well.
Submit the form and the documents and wait for the bank representative to give you an acknowledgment slip for reference.
Next will be the verification process which will include the validation of your KYC details to check whether the mobile number you have provided matches.
You will then receive a confirmation message on the linked/updated mobile number.
Now you can set up mobile banking services easily by downloading the official app of the bank.

Offline and online methods

There are two ways in which you can link your mobile number to your bank account, via internet or by visiting the ATM nearby. Let’s understand the steps for each –

Internet/mobile banking	Bank ATM
Log into your mobile banking account	Visit the nearest ATM kiosk
Go to the ‘My Account’ or ‘My Profile’ tab	Insert your ATM/debit card and enter the PIN
Under ‘My Account’ you will find the ‘contact number tab’. If you have multiple accounts choose the desired one to link your number	Tap on the main menu and select the ‘Register Mobile Number’ option
After this, you will have to go through one last authentication step. This varies from bank to bank.	Enter your 10-digit mobile number you wish to link
You will be redirected to a new tab providing you two options, either add a mobile number or change/update existing one	Now you will receive an OTP which you have to enter
Make your choice and enter the mobile number	Click ‘confirm’ to complete the linking process
The page will prompt you to confirm the entered number on a separate tab
Click on ‘Submit Request’
Your bank will then send you an OTP, enter this OPT and click on ‘Submit’
Within 1-2 days, your mobile number will be linked to your bank account

Both methods are equally useful, you just need to understand what is more suitable for you.
