New Delhi: Losing access to a long-held mobile number registered with your bank account can be a highly stressful experience, especially in an era where digital transactions rely heavily on One-Time Password (OTP) verifications. If your old mobile number has been permanently deactivated and you cannot reactivate it, there is no need to panic. Modern banking facilities offer several convenient, hassle-free ways to update your contact details without having to stand in long queues at a bank branch.
Updating via Internet Banking For customers with active online banking credentials, updating contact details is a seamless process. Users can simply log into their bank’s official internet banking portal to initiate the change. Once logged in, navigate to account settings, usually labelled as ‘Profile,’ ‘Personal Details,’ ‘My Profile,’ or ‘Contact Details.’ By selecting the option to change the registered mobile number, you can input your new contact details. The bank will then authenticate your identity through an alternative verification method, after which the new number will be successfully registered.
Updating via ATM If you do not have internet banking activated, your debit card can serve as an easy alternative. Many prominent banks allow customers to update their mobile numbers through their ATM networks. To utilize this feature, visit your bank’s nearest ATM, insert your debit card, and enter your confidential PIN. Look for menu options such as ‘Registration,’ ‘Mobile Number Update,’ or ‘Update Contact Details.’ The system will prompt you to enter the new mobile number and complete the on-screen verification instructions to finalize the update.
Alternatively, customers who prefer the traditional route can always visit their home branch and submit a physical application form to change their details.
Prioritising Cyber Safety While the process is straightforward, financial experts urge customers to exercise extreme caution when updating sensitive banking information. It is crucial to use only official banking applications or verified bank websites.
Customers are strictly advised against clicking on any unverified links received via SMS or WhatsApp that claim to facilitate mobile number updates, as these are common phishing traps used by cybercriminals. Finally, once the update process is complete, experts recommend performing a minor transaction to verify that the new mobile number is correctly linked and actively receiving SMS alerts.
