What We Know About This Number
04 8398 7512 is registered to Optus Mobile (serviceType: mobile). At this stage, only one report exists in the community database, so patterns cannot yet be reliably assessed. The report came from a missed call on a mobile device with no follow-up contact or message.
Silent or callback-fishing calls are common tactics used by both scammers and aggressive telemarketers. A single missed call with no voicemail from 0483987512 fits this pattern, though one report alone is insufficient to confirm intent.
What to Do If You Receive a Call from 04 8398 7512
If 04 8398 7512 calls you:
- Do not: Answer if you don't recognise the number, return the call to verify the caller, or provide any personal information

WRITE A REVIEWFrequently Asked Questions
Why would someone call from 04 8398 7512 and leave no message?
Silent or no-message calls are commonly used to test if a number is active and answered by a human. Scammers and aggressive telemarketers use this tactic to build lists of valid numbers. If 0483987512 calls again without leaving a message, it may indicate your number is on a target list.
Is 04 8398 7512 definitely a scam?
Not necessarily. One contributor reported 0483987512 as suspicious, but a single missed call without follow-up is not conclusive evidence of scam activity. However, the lack of voicemail is a red flag - legitimate callers typically leave a message if they need to reach you.
Should I call 04 8398 7512 back to see who it is?
No. Do not call back 0483987512. Callback fishing is a common tactic where scammers use one-ring or no-message calls to trick people into returning the call at a premium number or connecting to a malicious line. If the caller was legitimate, they would have left a voicemail.
Can I block 04 8398 7512 on my phone?
Yes. Most Australian mobile phones allow you to block numbers directly. On most devices, you can long-press the number 0483987512 in your call log and select 'Block' or 'Add to blacklist'. If 04 8398 7512 continues to call, blocking prevents further contact.
What if 04 8398 7512 is a legitimate business trying to reach me?
A legitimate business will leave a voicemail message explaining who they are and why they called. If 0483987512 doesn't leave a message and calls multiple times, it's not legitimate contact. You can always contact organisations directly using their official website or directory to follow up.
How many people have reported 04 8398 7512?
Currently, only one contributor has reported 0483987512 to Reverseau. This limited data means we cannot yet confirm a clear pattern of scam or spam behaviour. If you receive calls from 04 8398 7512, adding your report helps establish whether this number is part of a larger operation.
