Keeping your personal information up to date is crucial for account security and communication. At Contoso, updating your details can be done easily through various methods. To update online, log in to your Contoso online banking account and navigate to the ‘Profile’ or ‘Account Settings’ section. Here, you can modify information like your address, phone number, and email address. If you prefer to update your details in person, visit your local branch with a valid form of identification. A customer service representative will assist you in processing your changes. For sensitive updates, like changing your Social Security number or marital status, we may require additional documentation. It’s important to ensure that all information is accurate to prevent any issues with account access or communication from the bank. Additionally, notify us of any significant changes promptly to ensure your account remains secure and up to date.
