Suspicious Activity Reports for 03 9099 7904
Two contributors have reported activity from 03 9099 7904 (also written as 0390997904), an Optus-allocated local service number in Victoria. The reports suggest potential scam or telemarketing behaviour, with callers making no attempt to leave voicemails and displaying evasive callback responses.
One contributor received a missed call from 0390997904 on 2 February 2026 with no message left. When they called back, the number responded with a generic recorded message: "Thank you for contacting us (?) all our representatives are not available." This pattern of missed calls followed by unhelpful callback messages is typical of scam operations or aggressive telemarketing campaigns.
What Reports Indicate About 03 9099 7904
The two reports about 03 9099 7904 mention a related number (03 9099 7907) receiving calls on the same date, suggesting a coordinated calling campaign. One contributor initially reported the wrong area code but clarified they had received calls from 02 numbers instead, though the Reverseau database shows 03 9099 7904 as the primary reported number.
Contributors found the callback experience suspicious: the recorded message greeting contains an unexplained gap (?) and vague language about representative availability, which differs from legitimate business voicemail systems. Neither caller attempted contact via voicemail, indicating they may not be genuine customer service calls.
Call Patterns and Timing
Both reports for 03 9099 7904 occurred on 2 February 2026, suggesting either a single calling campaign or multiple attempts within a short timeframe. One call was missed without voicemail; the other was answered by the contributor. The fact that 0390997904 is listed as an Optus local service number in Victoria may give the calls a false appearance of legitimacy, a tactic commonly used in scam operations that spoof or misuse legitimate provider allocations.
The related number mentioned (03 9099 7907) adds context that this may be part of a wider dialling list, where scammers or telemarketers cycle through similar numbers to increase call volume and success rates.
What to Do If You Receive a Call from 03 9099 7904
If 03 9099 7904 calls you:
- Do not: Answer if you don't recognise the number, return the call, or engage with any callback prompts
- Do: Let calls go to voicemail, block the number immediately if it calls again, and never provide personal or financial information
- Do: If you do answer by mistake, hang up without confirming your identity or availability
- Do not: Trust the caller's claimed identity - verify any legitimate business through official channels (look up the organisation's website independently)
The generic voicemail greeting from 0390997904 combined with no initial message attempt suggests this is not a genuine business trying to reach you urgently.

WRITE A REVIEWFrequently Asked Questions
Why did 03 9099 7904 call me but leave no voicemail?
Contributors report that callers from 03 9099 7904 (0390997904) made no attempt to leave voicemails, which is unusual for genuine customer service. Scammers and telemarketers often rely on repeated calling to reach targets rather than voicemail, and they avoid leaving messages that could be used as evidence. The fact that 0390997904 shows a vague callback message instead suggests low-effort operation typical of scam campaigns.
What does the message from 03 9099 7904 mean?
When a contributor called back 03 9099 7904, they received: "Thank you for contacting us (?) all our representatives are not available." This awkward message with an unexplained gap suggests a poorly configured auto-responder or intentionally vague recording. Legitimate businesses use professional voicemail systems with clear caller instructions. The unclear message is consistent with scam operations testing which callback numbers generate responses.
Is 03 9099 7904 a real business number?
03 9099 7904 (0390997904) is allocated as a local service number in Victoria by Optus Networks, but allocation alone does not confirm legitimacy. Scammers frequently spoof or misuse legitimate provider allocations to appear trustworthy. The combination of missed calls with no voicemail and a vague callback message from 0390997904 suggests this number is being used for unauthorised purposes, not genuine Optus customer service.
What should I do if 03 9099 7904 calls again?
If 03 9099 7904 (0390997904) calls you a second time, block the number immediately on your phone. Do not answer, do not return the call, and do not engage with any automated messages. Contributors who received calls from 0390997904 and called back found only a suspicious generic message. Blocking prevents repeated contact and protects your privacy from potential scam campaigns cycling through calling lists.
Could 03 9099 7904 be a legitimate company?
While 03 9099 7904 has a Victorian Optus allocation, the calling behaviour reported by contributors is inconsistent with legitimate business: missed calls without voicemail, no caller identification, and evasive callback messaging. If a real company needs to contact you about an account or service, they will identify themselves clearly on voicemail and follow professional communication protocols. The pattern from 0390997904 matches scam and telemarketing tactics, not legitimate business outreach.
Should I report 03 9099 7904 to authorities?
Yes. Report 03 9099 7904 (0390997904) to Scamwatch at scamwatch.gov.au or ACMA at acma.gov.au, especially if the pattern of missed calls from 0390997904 repeats or escalates.
