0420 110 100 (0420110100): Contributors report daily repeated calls after 3pm from rotating 0420 numbers. No messages left, possible spoofing.
Repeated Calls from 0420 110 100
Three contributors have flagged 0420 110 100 (also written as 0420110100) for suspicious calling behaviour. The most recent report describes a persistent pattern of daily calls starting after 3pm, with the caller rotating through a series of 0420 mobile numbers including 0420110190, 0420959265, 0420110274, 0420110306, 0420110334, 0420112341, and 0420110409. This rotating number tactic is typical of spoofing or automated calling systems designed to evade blocking.
The contributor who reported 0420 110 100 emphasises the timing consistency, noting calls arrive daily in the late afternoon window. Two additional reports mention that calls from 0420110100 and related numbers produce no voicemail and appear to use number spoofing, where the caller ID shows different numbers on each contact attempt.
What Callers from 0420 110 100 Do
Contributors receive calls from 0420 110 100 that immediately disconnect or hang up without message. One report specifically notes the caller leaves no voicemail despite repeated attempts. The spoofing behaviour reported in connection with 0420110100 suggests automated systems or intentional obfuscation to prevent identification and blocking.
The pattern of multiple similar 0420 numbers being used in quick succession indicates a coordinated campaign rather than occasional wrong numbers. The fact that callers from 0420 110 100 rotate through different digits (0420110100, 0420110190, 0420110274, etc.) makes it difficult for contributors to block the source permanently.
Report Patterns and Timing
One contributor described receiving calls from 0420 110 100 and the related series every single day, consistently after 3pm. This regularity suggests automated dialling rather than manual contact attempts. The contributor reported the calls to 0420110100 via answered call, indicating the number is actively operational and connecting to recipients.
Two additional contributors received calls from similar 0420 numbers but missed them, with no voicemail left behind. This silence-and-hang-up pattern combined with the rotating number usage creates frustration and difficulty in tracking the actual caller.

WRITE A REVIEWFrequently Asked Questions
Why does 0420 110 100 use so many different numbers?
The caller appears to be using number spoofing, where the displayed caller ID changes on each attempt. One contributor reported 0420 110 100 rotating through at least eight different 0420 numbers (0420110190, 0420959265, 0420110274, 0420110306, 0420110334, 0420112341, 0420110409) over consecutive days. This tactic makes it harder for recipients to block the source, as blocking one number (0420110100) doesn't stop calls from the other variations. It also suggests an automated system rather than a person calling.
What should I do if 0420 110 100 keeps calling despite blocking?
If calls from 0420110100 continue after you've blocked the primary number, you'll need to block each rotating variant as it appears. Additionally, contact your mobile provider (Telstra, Optus, Vodafone, etc.) and report the entire 0420 number range being used. Providers can sometimes implement carrier-level blocking. You can also lodge a complaint with ACMA at acma.gov.au about the persistent spoofing behaviour associated with 0420 110 100.
Is 0420 110 100 a scam or just spam?
Based on current reports, 0420 110 100 appears to be spam rather than an active scam. Contributors have reported calls that hang up without message or engagement. However, the repeated-calls pattern and spoofing behaviour indicate intentional harassment. Because the caller leaves no message and uses rotating numbers, it's difficult to determine the ultimate intent. Treat any call from 0420110100 with caution and do not engage or provide information.
Why are calls from 0420 110 100 happening every day at the same time?
One contributor specifically noted calls from 0420 110 100 arriving every day after 3pm. This consistency strongly suggests automated dialling from a robocall or spam campaign system. Such systems are programmed to target numbers at specific intervals. The fact that 0420110100 rotates through different numbers while maintaining the 3pm timing suggests a coordinated campaign designed to circumvent blocking by changing the displayed caller ID.
What should I report when I contact ACMA about 0420 110 100?
When reporting 0420110100 to ACMA at acma.gov.au, include: the primary number (0420 110 100), the date and time of calls, that calls occur daily after 3pm, the rotating numbers you've observed (0420110190, 0420959265, etc.), that no voicemail is left, and that number spoofing appears to be occurring. Provide as much detail as possible about the calling pattern so ACMA can investigate the source and potentially take enforcement action.
Can my mobile provider stop calls from 0420 110 100?
Yes, contact your mobile provider (Telstra, Optus, Vodafone, or others) and report the repeated calls from 0420 110 100 and the associated rotating numbers. Many providers offer carrier-level call filtering and can implement barring rules for persistent spam sources. When you call, explain that 0420110100 is using spoofing to rotate through multiple similar numbers, and request they investigate and block the originating source. This may be more effective than blocking individual numbers on your phone.
