One community report for 04 0396 8184 (0403968184) - Optus mobile number with strange calling behaviour including middle-of-night contact and hang-ups.
Suspicious Activity Reported for 04 0396 8184
A single contributor has flagged 04 0396 8184 (also written as 0403968184) for suspicious calling behaviour. The report describes a call received during late night hours, with the caller refusing to engage when the recipient attempted to return the call. When the number later called back and was answered, the caller hung up immediately without explanation.
The number is registered as an Optus mobile service, which makes the pattern particularly unusual given that legitimate callers typically respond when their calls are returned. The combination of unsolicited middle-of-night contact and deliberate disconnection suggests either intentional evasion or a probe call to test if the number is active.
What This Call Pattern Indicates
The behaviour reported with 0403968184 differs from typical spam or scam approaches. Rather than attempting a pitch or extracting information, the caller from 04 0396 8184 made contact during an unusual hour, avoided engagement when called back, and then hung up when reached. This pattern is sometimes associated with:
- Number verification scams (testing active numbers for resale or targeted attacks)
- Callback fraud attempts (establishing connection for later exploitation)
- Harassment or intimidation probing
- Unwanted contact from someone known to the recipient

WRITE A REVIEWFrequently Asked Questions
Why would someone call from 04 0396 8184 in the middle of the night and then hang up?
The contributor's experience with 04 0396 8184 suggests deliberate evasion rather than a genuine contact attempt. This pattern sometimes indicates number verification (testing if your number is active and monitored), harassment probing, or callback fraud setup. The fact the caller wouldn't engage when 0403968184 was called back supports intentional avoidance rather than accidental dialling.
Is 04 0396 8184 definitely a scam?
Based on the single report available, 04 0396 8184 shows suspicious behaviour but hasn't been definitively identified as a known scam. The unusual call timing, refusal to engage, and immediate hang-up when answered are red flags worth noting. If you experience similar contact from 0403968184, report it to Reverseau so patterns can be identified.
Should I block 04 0396 8184?
Yes, blocking 0403968184 is reasonable if you've received an unexplained call, especially during unusual hours. Most phones allow you to block numbers directly in settings. Since 04 0396 8184 didn't engage when called back, there's little risk of blocking a legitimate contact - genuine callers leave messages or try again.
What should I do if 04 0396 8184 calls me again?
If 0403968184 calls multiple times with the same pattern (middle-of-night, hanging up), note the dates and times, let it go to voicemail, and don't return the call. Block the number in your phone and report it to Optus (your mobile provider) and ACMA at acma.gov.au. Each report strengthens community awareness of 04 0396 8184's behaviour.
Is this number actually from Optus?
04 0396 8184 is registered to Optus as a mobile number, but caller ID can be spoofed. The number shows as Optus-allocated in phone registries, but that doesn't guarantee the actual caller is an Optus customer or legitimate representative. Always treat unknown calls with caution, especially 0403968184 given the suspicious hang-up pattern.
What is 'number verification' and how does it relate to 04 0396 8184?
Number verification is when scammers test whether a phone number is active and monitored before targeting it with a full attack. The behaviour reported for 04 0396 8184 - calling at odd hours, refusing callback, hanging up when answered - fits this pattern. If 0403968184 is a probe call, you may see escalation to actual scam attempts later, making blocking and reporting important.
