WRITE A REVIEWFrequently Asked Questions
Why would a scammer use a number so similar to mine?
Spoofing a number nearly identical to yours (like 04 6831 2000 when yours differs by one digit) is a deliberate tactic to increase answer rates and build false trust. You're more likely to pick up a call that looks like it could be from your own number or a contact you know. Contributors receiving calls from 0468312000 report this similarity making them pause before realising it wasn't legitimate.
Is 04 6831 2000 actually an Optus number?
The number 04 6831 2000 is registered as an Optus mobile service, but this doesn't guarantee the person calling is actually from Optus or using it legitimately. Scammers can spoof legitimate mobile numbers or compromise accounts. Always verify independently by hanging up and calling your provider directly using a number you find yourself.
What should I do if I already answered a call from 0468312000?
If you answered 0468312000 and didn't share personal information, block the number immediately and monitor your accounts. If you provided any details (passwords, banking info, personal identity numbers), contact your bank and phone provider right away. Don't provide additional information if they call back.
How can I block 04 6831 2000 on my Optus phone?
On most smartphones, you can block 04 6831 2000 by opening the call history, tapping the number, and selecting 'Block' or 'Report as Spam'. You can also contact Optus on 133 937 to report the number for spoofing and request blocking assistance.
Should I call back 0468312000 to see who it is?
No. Do not call back 0468312000 or any number that has called you from an unknown source. Callback scams often route to premium-rate numbers or overseas lines that charge excessive fees. If you're curious about the call, use Reverseau or Scamwatch to check the number first.
What is 'number spoofing' and how do scammers do it?
Number spoofing is when a caller displays a false phone number on your caller ID.
