Keep Your Account Secure and Up to Date
Maintaining accurate contact information with ANZ is essential for the security and smooth operation of your everyday banking. If your phone number, email, or residential address changes, updating these details promptly helps ensure you continue receiving account alerts, digital statements, and replacement cards sent by mail.
Crucially, an up-to-date mobile number is required to receive SMS security codes for Multi-Factor Authentication (MFA) when approving transactions, making large transfers, or logging into new devices. This guide walks you through the straightforward process of updating your contact details securely via ANZ Internet Banking.
Update Requirements
| Category | Details |
|---|---|
| Prerequisites | Active ANZ Internet Banking access and, where applicable, access to your registered mobile number or authentication method for verification. |
| Eligible Details | Mobile and landline numbers, email addresses, residential and postal addresses. |
| Processing Time | Updates to digital contact details are typically applied to your profile instantly. |
Step-by-Step Contact Update Algorithm
- Step 1: Navigate to the official ANZ website and click Log On using your ANZ Internet Banking login credentials (which may include a Customer Registration Number or username depending on your account type).
- Step 2: From your main dashboard, navigate to the Profile or Settings menu, usually located in the top navigation bar.
- Step 3: Select Personal Details or Contact Details from the drop-down options to view your current information.
- Step 4: Click the Edit button next to the specific detail (phone, email, or address) you need to change, and carefully input your new information.
- Step 5: Click Save or Submit. You will be prompted to confirm this high-security change by entering a one-time passcode sent to your existing mobile number or via the ANZ Shield app.
Pro-Tip: If you are planning to change your primary mobile phone number, always update it in ANZ Internet Banking before you disconnect your old number. Since you need an SMS code sent to your old number to authorize the change, failing to do this beforehand is a common efficiency trap that will force you to visit a physical ANZ branch or call customer support to verify your identity.
Troubleshooting Common Update Issues
- MFA Delays: If you are not receiving the security code required to save your new contact details, ensure your current phone has cellular reception. If SMS fails, use the ANZ Shield app to generate an instant offline authentication code.
- Browser Errors: If the save button is unresponsive or the portal times out while you are typing your new address, it is likely a cookie issue. Clear your browser cache or perform the update in a clean "Incognito" or "Private" window.
- Locked ID: Entering incorrect login details multiple times will lock your CRN to prevent unauthorized profile changes. Click the Forgot Details link to securely reset your credentials, or contact ANZ support to unlock your profile.
Frequently Asked Questions
Can I change my legal name through ANZ Internet Banking?
No. While you can update your address, email, and phone number online, changing your legal name is a strict security process that requires you to visit an ANZ branch in person with certified documentation, such as a marriage certificate or deed poll.
Will updating my address update it for my joint accounts too?
Updating your residential or postal address under your personal CRN typically updates it across all linked accounts, including joint accounts. However, the other joint account holder will still need to log in to update their own distinct profile if they have also moved.
