How can you update the mobile number that is associated with your ICICI bank account?

You can update your contact details in various ways. Either you can visit the bank to do the task or get the assistance of the ICICI customer helpline to complete the task.

We will discuss all of them here.

Changing contact details at the branch

Here’s the process for doing it:

  • Visit the ICICI Bank where you maintain your bank account.
  • Get the personal detail update form or download it from the ICICI official website.
  • Now, accurately fill out the form and allow the concerned staff to verify it.
  • The bank may ask for KYC documents; produce them if asked.
  • Once the verification process is done, your mobile number will be changed in the system.

Changing contact details with ICICI Customer Care

You may also get assistance from the ICICI customer helpline to change your personal details, including your registered mobile number.

This sort of service is especially meant for NRI customers, though as a resident of India, you may be able to use the service too. Here’s the link to the ICICI customer helpline, where you can call the toll-free number as well as request a call.

If you are an NRI, you can raise a service request through ICICI customer helpline portal. There is a designated portal for handling queries and service requests for NRI only.

Changing contact details with e-Mail

The last is sending an email to your ICICI branch. If you send the request along with your valid documents, the bank may update or change your registered mobile number.

However, the process may not work if the bank is unable to establish your credential. To make it happen, your signature must be matched with other personal data that is in your KYC documents.

The best practice is to visit the bank personally and make the request on the spot with all the relevant documents.
