WRITE A REVIEWFrequently Asked Questions
Is 04 0390 4600 a legitimate business number?
This is an Optus mobile number that has been reported for telemarketing activity. While the number itself is a standard Australian mobile format, the contributor's report indicates it's being used for unsolicited sales calls rather than a mainstream business line. Legitimate businesses typically use fixed landlines or clearly identified corporate numbers for customer service.
Why does 0403904600 keep calling if I don't answer?
Repeated calls from 04 0390 4600 suggest systematic telemarketing operations that use auto-dialling systems to maximise call volumes. When calls go unanswered, the system may retry the number multiple times. Blocking the number and registering with the Do Not Call Register at donotcall.gov.au should reduce further contact.
Can I block 04 0390 4600 on my phone?
Yes. On most Australian phones, you can block 0403904600 directly through your phone settings or by using your provider's call filtering service. Optus customers can use Optus Call Guard to filter spam and telemarketing calls. Blocking this number will prevent future calls, though the telemarketer may attempt contact from other numbers.
What should I do if 0403904600 claims to represent a company I know?
Do not assume the caller is legitimate. Telemarketers sometimes impersonate well-known brands or claim false affiliations. If 04 0390 4600 claims to represent a specific company, hang up and contact that company directly using the phone number on their official website to verify the call was genuine.
Is it safe to return a call to 04 0390 4600?
No. Returning calls to 0403904600 confirms your number is active and monitored, which may increase telemarketing contact. It also risks connecting you to premium-rate services or scams disguised as legitimate businesses. Do not return calls from unknown telemarketing numbers.
How do I report 0403904600 to ACMA?
You can lodge a telemarketing complaint about 04 0390 4600 with ACMA at acma.gov.au. Provide details of the calls, dates, and what the caller claimed. If the number appears on the Do Not Call Register, ACMA can investigate breaches of telemarketing compliance rules. Multiple complaints about 0403904600 strengthen enforcement action.
