Identifying the Threat: 02 4012 3521

The phone number 02 4012 3521 / 0240123521 has been flagged multiple times by users as a potential scam call. Several reports indicate that this number claims to be from Optus, alleging issues related to service suspensions or bill payment failures, which is a common tactic among scammers looking to extract sensitive information.

A Pattern of Deception

Users have noted that the calls are often made with non-English messages, making it immediately suspicious. In fact, the reports indicate that many individuals who did not answer the call received no voicemail. This behaviour is typical of spam or scam callers who rely on the element of confusion to trick individuals into returning the call.

Type of Scam

This specific case falls under the category of identity theft scams. Scammers posing as legitimate companies like Optus tend to create a sense of urgency, either by claiming that your service is about to be suspended or that there has been a failure in payment. Such tactics are designed to panic the recipient into providing personal information like bank details or identification numbers.

How to Handle Incoming Calls from This Number

  • Do Not Answer: If you do not recognise the number, it is best to let it go to voicemail. As indicated by user reviews, this number often fails to leave a message.
  • Block the Number: If you receive repeated calls from this number, consider blocking it on your device to prevent further contact.
  • Report the Number: Reporting scam numbers can help others protect themselves. You can report scam calls to the ACMA (Australian Communications and Media Authority) or through your service provider.
  • Stay Informed: Tools such as Reverseau can provide valuable insights into unknown numbers. Using a Reverse Phone Lookup in Australia gives you the ability to identify the source, helping to prevent falling victim to scams.

Conclusion

The phone number 02 4012 3521 / 0240123521 is not a legitimate contact and should be treated with caution. By staying vigilant and sharing information, you can protect yourself and others against potential scams. If you're ever unsure about a call, remember that reputable companies will never ask for sensitive details over the phone.

This caller is a spammer showing up from Nelson Bay NSW, mass calling to several of my work mobiles all with trailing numbers. This was a scam caller due to the region calling no calls were answered and of course they don’t leave VM.
