How to update mobile number of my ICICI Bank Saving Account?
You can update the mobile number through any of the following channels:
 
ICICI Bank ATM:
Visit the nearest ICICI Bank ATM > Select ‘More options’ > Register your Mobile > Enter the mobile number. Your mobile number will be updated in 1 working day.
 
ICICI Bank branch:
Please visit the nearest ICICI Bank branch along with your original photo ID proof. Once the request is made, your mobile number will be updated in 2 working days. To locate the nearest ICICI Bank Branch, visit maps.icicibank.com/mobile
 
We have discontinued mobile number registration/ de-registration/ modification through our Customer Care and internet banking due to security reasons.
