Community reports for 03 7040 9389 (0370409389): Callers attempting to extract personal details with suspicious and nonsensical voicemails.
Personal Information Scam Reports for 03 7040 9389
Two contributors have reported suspicious activity from 03 7040 9389 (also written as 0370409389), a Melbourne-based local service number provisioned by Optus Networks. One report describes a direct scam attempt where the caller actively fished for personal details, while another contributor noted evasive behaviour with repeated calls leaving garbled voicemails.
The pattern suggests deliberate obfuscation - one contributor characterised the voicemail content as nonsensical, consistent with tactics used to evade call filtering systems or avoid recognition by return callers. The combination of personal information requests with suspicious messaging indicates 0370409389 may be operating a phishing operation rather than legitimate customer service.
What Callers from 03 7040 9389 Are Doing
The contributor who answered a call from 03 7040 9389 reported the caller directly attempting to extract personal details. This is a hallmark of identity theft and financial fraud schemes where callers pose as trusted organisations to harvest information like banking credentials, dates of birth, or account numbers.
The second report about 0370409389 documents voicemail messages described as nonsensical or incoherent. This approach is often deliberate - callers leave garbled recordings to avoid transcript evidence and to discourage callbacks from suspicious recipients. The contributor noted they have been actively avoiding this number, suggesting repeated calling behaviour.
Call Patterns and Timing
Both reports for 03 7040 9389 were logged on the same date in October 2025, with one incoming call answered and one leaving a voicemail. The Melbourne origin combined with the Optus local service allocation suggests the number may be spoofed or compromised rather than legitimately provisioned. The use of a local service number (rather than 1300, 1800, or mobile) is a common tactic to appear trustworthy and increase answer rates.
