TL;DR: Caller Check lets a real bank caller prove who they are by sending a notification inside your banking app (ASB Mobile Banking; ANZ goMoney). In July 2026, ANZ warned scammers are faking it, sending "security verification" by email, SMS or WhatsApp. Rule: if the check doesn’t appear in your bank’s app, it’s a scam. Hang up and call the bank’s published number.
How real Caller Check works
- ASB: ask the caller for a Caller Check notification; legit ones show in the ASB Mobile Banking app (ASB).
- ANZ: Caller Check is a secure notification sent only to the ANZ goMoney app. It isn’t available if you don’t use goMoney (ANZ).
How the scam copies it
ANZ’s July 2026 warning:
- A scammer cold calls, claiming to be ANZ.
- They send a fake "security verification" by email, SMS or WhatsApp.
- They insist verification has to happen through that channel.
ANZ: "If you receive one anywhere other than goMoney, it’s a scam."
It’s a bit like a burglar showing you a laminated card that says "Genuine Police Officer." The real badge is in your app, not in your inbox.
What to do when a "bank" calls
- Ask for a Caller Check in your app.
- If nothing appears in the app, hang up.
- Call back on the number on your card or the bank’s website.
- Never share login details, full card details or two-factor codes.
- Don’t click links or call numbers from unexpected messages.
Banks’ "never" lists
| Bank | Never asks for |
|---|---|
| ANZ | Internet Banking logins, full card details, 2FA codes |
| ASB | Passwords, PINs, text codes, token codes, Netcodes; reading out codes |
