Keeping your contact information current is critical for account security and seamless communication. For Australian ANZ customers, your mobile phone number is commonly used to receive Multi-Factor Authentication (MFA) codes, fraud alerts, and account notifications.
If you have recently switched mobile providers or lost your device, updating your phone number should be your immediate priority. This guide provides the exact steps to securely update your contact details via ANZ Internet Banking, ensuring you never lose access to your financial toolkit.
Steps to Update Your ANZ Phone Number
- Navigate to the official ANZ website and click the Log on button.
- Select ANZ Internet Banking, then enter your Customer Registration Number (CRN) and Password.
- Authenticate your session using an SMS code or the ANZ Shield app.
- Go to the Settings or Profile section (the exact label may vary depending on the platform).
- Select Update contact details and find the Mobile phone number field.
- Enter your new number, review for accuracy, and click Save. You may need to verify this change via your existing authentication method.
Troubleshooting Common Update Issues
- MFA Code Sent to Old Number: If you no longer have access to your old number, you may need to authenticate using the ANZ Shield app or contact ANZ support for assistance updating your details.
- Browser Caching Errors: If the new number won't save, clear your browser's cache and cookies. Close the browser completely, reopen it, and attempt to click Save again.
- Locked Customer ID: Multiple failed attempts to verify your new number can trigger a security lock. Use the Forgot password function to verify your identity or visit an ANZ branch.
Pro-Tip: Transition your MFA method to the ANZ Shield app before changing your phone number. This bypasses the need for SMS verification, making the update process significantly faster and safer, especially if you are traveling overseas.
