WRITE A REVIEWFrequently Asked Questions
Why is 0423 903 023 asking for payment over the phone?
Community reports indicate 0423 903 023 is being used to target business owners with fake vendor or supplier pitches, attempting to pressure immediate payment authorisations. Callers are likely attempting to process fraudulent transactions using stolen credit card details. Legitimate vendors will always provide written quotes, invoices, and allow time for verification through established channels.
Is 0423903023 a legitimate Optus number?
The number 0423903023 is registered to Optus Mobile, but this does not mean the caller is legitimate. Scammers frequently spoof or use stolen mobile numbers to appear credible. The contributor reports confirm that despite the Optus registration, 0423 903 023 is being actively used for payment fraud.
What should I do if I already gave payment details to this number?
Contact your bank or payment provider immediately and report the fraudulent transaction. Request that your card be cancelled and monitor your account for unauthorised charges. Also report the incident to ReportCyber at cyber.gov.au and Scamwatch at scamwatch.gov.au. If you provided business banking details, contact your business bank's fraud team urgently.
Can I report 0423 903 023 to the police?
Yes, you can report payment fraud involving 0423 903 023 to your local police station or through cyber crime reporting at cyber.gov.au. You should also report to the ACMA at acma.gov.au, which investigates misuse of Australian phone numbers. Scamwatch at scamwatch.gov.au accepts reports and publishes alerts about active scams.
Why do scammers use mobile numbers like 0423 903 023?
Mobile numbers appear more personal and harder to trace than business lines, making them seem less suspicious to busy decision-makers. Scammers targeting businesses use mobile numbers to bypass corporate screening and to create urgency. The number 0423903023 being Optus-registered adds a layer of apparent Australian legitimacy.
Should I block 0423 903 023 permanently?
