The Branch Manager,
Dear Sir/ Madam,
Sub: – Address change in my account
I am an account holder in your bank having account no 612669646133. I am writing to request a change in the mobile number associated with my account. My current mobile number, [Old Mobile Number], is no longer in use, and I would like to update it with my new mobile number, [New Mobile Number].
I understand that the mobile number linked to my account is crucial to receive SMS alerts for any transaction or communication related to my account. Therefore, I would greatly appreciate it if you could make the necessary changes as soon as possible.
I have enclosed a copy of my government-issued ID and the latest bill from the new mobile service provider as proof of my new number.
Thank you for your assistance in this matter.
