Five contributors have reported calls from 03 9003 4807 (also written as 0390034807) characterised by immediate disconnections and evasive behaviour. The most consistent pattern is callers hanging up within seconds of connecting, or remaining silent before terminating the call. One contributor noted the caller spoke only gibberish before ending the conversation, while another found that when they attempted to call back 0390034807, the number was not connected.
The behaviour reported from 03 9003 4807 suggests potential callback scam activity or automated testing of active phone numbers. This type of pattern is often associated with systems that verify working numbers for later targeting or sale to scammers.
What Callers from 03 9003 4807 Do
Contributors describe highly evasive behaviour from this number. One report details a caller who spoke only gibberish before hanging up, making any legitimate communication impossible. Another contributor experienced a call that lasted just five seconds before disconnection, then when they called back 0390034807 to investigate, a male voice answered but immediately dropped the call when asked why he had called.
A silent call pattern is also evident, with one report of 03 9003 4807 ringing and hanging up without leaving a message. When contributors attempted to call back the number, they found it was not connected, suggesting the call may have originated from a spoofed or temporary line rather than a legitimate business.
Report Patterns and Behaviour
All five reports of 03 9003 4807 describe answered calls rather than missed calls or voicemails. The timing of the reports spans from mid-February to early March 2026. The evasiveness when called back is particularly notable - the contributor who attempted to verify the caller's identity was met with an immediate disconnect, suggesting the caller either knew they had been identified or was testing the number's validity.
One contributor categorised their experience with 0390034807 as a definite scam based on the gibberish speech and abrupt hang-up. Others marked the calls as suspicious or nuisance due to the hang-up-without-explanation pattern. The consistency of immediate disconnection or unintelligible speech across multiple reports suggests this is a systematic approach rather than misdial or technical fault.

WRITE A REVIEWFrequently Asked Questions
What does it mean when a number like 03 9003 4807 calls and immediately hangs up?
When 03 9003 4807 calls and hangs up within seconds, it often indicates callback scam testing or automated number verification. Scammers use this tactic to confirm your number is active before adding it to scam call lists. The contributor who attempted to call back 0390034807 found this out directly when the caller abruptly ended the call upon questioning, suggesting they were testing rather than attempting genuine contact.
Is it safe to call back 0390034807 if I missed the call?
No, it is not safe to call back 0390034807. One contributor who attempted to return the call experienced immediate disconnection, and another found the number wasn't actually connected when dialled. Calling back unknown numbers like 03 9003 4807 can result in unexpected charges, exposure to scam activity, or confirmation to the caller that your number is active and monitored.
Why would someone call 03 9003 4807 and speak only gibberish?
Gibberish speech from 03 9003 4807, as reported by one contributor, can indicate a misdirected call, a technical glitch in an automated system, or intentional confusion tactics to make the interaction seem accidental or unrelated to scam activity. However, combined with the immediate hang-ups reported by other recipients, it suggests systematic, deliberate calling behaviour rather than genuine communication.
Should I block 03 9003 4807 immediately?
Yes, blocking 03 9003 4807 (0390034807) is recommended based on the five community reports describing hang-ups, silent calls, and evasive behaviour. Blocking prevents further contact and protects your number from being used in callback scam chains. Most phone providers allow you to block numbers directly in your settings, and once blocked, calls from 03 9003 4807 will go straight to voicemail.
What should I do if 03 9003 4807 calls repeatedly?
If 0390034807 calls repeatedly, first block the number in your phone settings. Then contact your phone provider to report the persistent calling pattern and request additional blocking measures. Finally, report the number to ACMA at acma.gov.au, as repeated hang-up calls from 03 9003 4807 fit the profile of unsolicited calling activity that ACMA investigates.
Why would a caller hang up when asked why they called from 03 9003 4807?
When the contributor asked the caller from 03 9003 4807 why they had called, the caller immediately dropped the line. This behaviour is consistent with callback testing or scam number verification, where the goal is to confirm an active number rather than conduct legitimate communication. The caller's evasiveness suggests they were not prepared for a direct challenge or were testing the line's validity.
