You can choose between two convenient methods to update your registered mobile number at Canara Bank. First is online banking. Login to your Canara Bank internet banking account and navigate to the "Profile" or "Settings" section. Locate the option for "Change Mobile Number" or similar wording. Enter your new mobile number and verify it using the One-Time Password (OTP) sent to your existing number (if accessible) or through an alternative method provided by the bank. Follow the on-screen instructions to complete the process. The second option is an in-person visit. Visit your nearest Canara Bank branch with a valid photo ID and your Canara Bank account details. Inform a bank representative that you wish to update your registered mobile number. They will provide you with a form to update your contact information. Fill out the form accurately, including your new mobile number, and submit it along with proof of your ID. The bank will process your request and update your registered mobile number within a few working days.
