How do I change the name used on my account?
To change the name on your account you must provide us with an original or certified copy of your change of name documentation, along with identification showing your current name.
You will need to visit your nearest branch with the documentation to request the change of name. If you do not live near one of our branches, please call us on 13 25 85 for further assistance.
