Scam Reports for 0420 123 745
A contributor has flagged 0420 123 745 (also written as 0420123745) as part of a coordinated scam pattern. The report indicates a scammer operating multiple similar numbers all beginning with 04120123xxx, suggesting a deliberate strategy to evade blocking by cycling through consecutive number variations.
The contributor noted receiving calls from this cluster of numbers over a two-week period before taking action to block them. This pattern of using sequential mobile numbers is typical of scammers attempting to increase the likelihood of reaching targets before numbers get reported and blocked.
Report Patterns and Timing
The report was submitted in mid-August 2026 and describes activity concentrated over a two-week window. The use of the 04 mobile number prefix indicates these calls were made from Australian mobile networks, though the actual caller location may differ from the registered area code.

WRITE A REVIEWFrequently Asked Questions
Why would a scammer use multiple similar numbers like 04120123xxx?
Scammers use sequential or clustered numbers to increase their chances of reaching victims before any single number gets widely reported and blocked. When 0420123745 gets flagged, they move to 0420123746, 0420123747, and so on. This rotating strategy keeps them ahead of blocking efforts and exploits the time lag between reports and action.
Should I answer if I see 0420 123 745 calling?
No. If the number is unknown and you've received reports like the one about 0420123745, let it go to voicemail. Legitimate organisations will leave a message, and you can verify the call by contacting them directly using an official number from their website-never using a number the caller provided.
What should I do if I already answered a call from 0420123745?
If you answered and the caller asked for money, personal details, or access to your accounts, do not comply. Hang up immediately. If you provided information, contact your bank, relevant government agency (like Services Australia if it was about myGov), or your identity protection service. Then report 0420 123 745 to Scamwatch and ACMA.
Can I block the entire 04120123xxx range?
Most Australian mobile carriers allow you to block number ranges or patterns. Contact your provider to ask about blocking all numbers starting with 04120123. You can also manually add individual numbers like 0420123745 to your phone's block list as they call.
Is 0420 123 745 definitely a scam or could it be legitimate?
One contributor reported 0420123745 as part of a scam cluster based on receiving repeated unwanted calls from similar numbers. While a single report doesn't guarantee every call from this number is malicious, the pattern of using sequential mobile numbers is a known scam tactic. If you receive a call claiming to be from a company, always verify independently rather than trusting the caller.
Where can I report 0420123745 and similar numbers?
Report 0420 123 745 to Scamwatch (scamwatch.gov.au), ACMA (acma.gov.au), and your mobile carrier. You can also contribute to Reverseau to help other Australians recognise this number and the 04120123xxx pattern. If you've lost money, report it to ReportCyber (cyber.gov.au) as well.
