- Suspicious
One contributor reports three calls from 04 6806 5621 (0468065621) within a week with no voicemail left. Unknown caller pattern on Optus mobile.
Repeated Calls from 04 6806 5621 with No Message
A single contributor has reported receiving three calls from 04 6806 5621 (also written as 0468065621) within one week. Notably, the caller left no voicemail message on any of the three occasions, which is unusual behaviour for legitimate callers.
The number is registered to Optus Mobile, an Australian mobile carrier. The pattern of multiple calls without leaving a message is a common characteristic of certain types of unwanted calls, including robocalls, callback scams, or spam operations that rely on call volume rather than direct communication.
What This Pattern Suggests
When a number calls repeatedly but never leaves a voicemail, it often indicates one of several possibilities. The caller may be testing whether the number is active, attempting to trigger a return call (callback scam), or simply running through a list of numbers as part of a spam or robocall campaign.
The fact that 0468065621 called three times within a single week suggests intentional contact rather than a misdial or accidental duplicate call. Legitimate businesses and organisations typically leave a message if the purpose is important, or call once and wait for a response.
What to Do If You Receive Calls from 04 6806 5621
If 04 6806 5621 continues to contact you:
- Do not: Answer the call if you don't recognise the number, return the call, or engage with the caller
- Do: Let it go to voicemail, check if a message is left, block the number on your phone if it calls again
- Do not: Click any links or respond to any follow-up SMS messages from this number
- Do: Verify the caller's identity independently if you suspect they may be legitimate - look up their organisation's official phone number and call that instead

WRITE A REVIEWFrequently Asked Questions
Should I answer a call from 04 6806 5621 if I don't recognise it?
No. If you don't recognise 04 6806 5621 (0468065621), let it go to voicemail. A legitimate caller will leave a message explaining their reason for calling. The reported pattern of three calls with no voicemail from this number suggests it's best to avoid answering.
What does it mean when a number calls multiple times but never leaves a voicemail?
Repeated calls from 04 6806 5621 without voicemail typically indicate either a robocall campaign, a callback scam attempt, or automated spam dialling. Legitimate callers almost always leave a message if the call is important. The contributor's experience with 0468065621 calling three times in one week with no message is a red flag.
Should I call back a number that called me but left no message?
It's not recommended. Calling back 04 6806 5621 without knowing who the caller is could connect you to a scammer or spam operation. Some scam tactics rely on getting you to call back. If you believe the call might be legitimate, verify the organisation's real phone number independently and call that instead.
Can I block 04 6806 5621 on my phone?
Yes. On most Australian phones, you can block 04 6806 5621 (0468065621) through your contacts or call blocking app. After blocking, calls from this number will go straight to voicemail or be rejected. If the calls continue from different numbers, that's a sign of a larger spam campaign.
Is 04 6806 5621 definitely a scam?
Based on the single report received, it's uncertain. The pattern - repeated calls with no voicemail - is suspicious, but we cannot confirm intent without more data. Report your own experience on Reverseau if you receive calls from 0468065621 to help establish whether this is spam, scam, or a legitimate caller with poor calling practices.
What should I do if I accidentally answer a call from 04 6806 5621?
Hang up immediately without providing any information. Do not confirm your name, address, or any personal details. Do not press any numbers if prompted. Block the number after ending the call, and report the experience on Reverseau. If 0468065621 sent an SMS or email follow-up, report it as spam through your mobile provider.
