WRITE A REVIEWFrequently Asked Questions
What does it mean if a number is spoofed?
A spoofed number is fake - the caller is disguising their true identity by making their call appear to come from a different phone number, in this case 04 4013 8826 (0440138826). Spoofing is often used to make scam calls appear legitimate or to hide the caller's real location and identity.
Why would someone call from 04 4013 8826 and not leave a message?
The contributor who reported 0440138826 received multiple calls with no voicemail left on any of them. This pattern is typical of probe calls or callback scams - the attacker is testing if your number is active, or trying to get you to call back a premium rate or spoofed number. Legitimate callers almost always leave a message explaining their reason for calling.
Should I call back 04 4013 8826?
No. Do not call back 0440138826 or any unknown number that calls you repeatedly without leaving a message. If the number is spoofed, you won't reach the actual caller anyway. If it's a callback scam, returning the call may connect you to a premium rate line or scammer.
Is 04 4013 8826 a real Optus number?
The number 0440138826 is allocated to Optus Mobile, but that doesn't mean the caller is actually from Optus. Spoofing makes it appear to come from a real number while the actual caller is elsewhere. Never assume a call is legitimate based on the displayed number alone.

What should I do if I get multiple spoofed calls like the one reported for 04 4013 8826?
Block each number as it appears, and report the pattern to ACMA at acma.gov.au. If calls escalate or become threatening, also report to Scamwatch at scamwatch.gov.au. Keep a record of dates, times, and any details from voicemails (if any are left).
