Why Callback Scams Target You
Callback scams rely on natural curiosity-when you miss a call, the instinct is often to ring back. Scammers exploit this by using spoofed or disconnected numbers that either connect to premium services (costing you money per minute) or, in some cases, to operators running secondary scams. The fact that 03 9003 8407 disconnects when called back suggests this particular number was specifically set up to trigger callbacks rather than handle inbound responses.

WRITE A REVIEWFrequently Asked Questions
What happens if I call 03 9003 8407 back?
Both contributors who attempted to ring back 0390038407 encountered a disconnected number tone. In callback scams, returning the call may either connect you to a premium-rate service (costing money) or a scam operator. Either way, calling back serves the scammer's purpose. Do not return calls to 03 9003 8407.
Why would someone call and then hang up?
Callback scammers deliberately miss-dial or use auto-diallers to trigger missed calls, knowing many people instinctively ring back unknown numbers. The reports for 03 9003 8407 and 0390038407 suggest this is a spoofed number specifically designed to prompt callbacks rather than answer them. Once you call back, the scammer's goal is achieved-either charging you premium fees or connecting you to a follow-up scam.
Could 03 9003 8407 be a legitimate business trying to reach me?
Unlikely. Legitimate businesses do not use spoofed or disconnected numbers. The fact that 0390038407 disconnects when called back strongly indicates it's not a genuine business line. If an organisation needs to reach you, they'll use a real, traceable number and leave a voicemail with clear details. If you suspect a business tried to contact you, contact them directly using the number on their official website-do not use any number from the missed call.
Is 03 9003 8407 always disconnected, or does it connect sometimes?
Both community reports for 0390038407 describe the number as disconnected when they attempted to ring back. This consistency suggests the number is either permanently spoofed or uses temporary numbering that is disabled after the initial miss-call. Either way, it's designed to be unreachable once you try to contact it, which is a classic callback scam indicator.
Should I block 03 9003 8407 on my phone?
Yes. Block 0390038407 immediately to prevent future calls. Most smartphone contact apps allow you to block numbers with a single tap. Additionally, consider reporting the number to your phone service provider so they can flag it in their systems. Even though 03 9003 8407 may be spoofed and used only once, blocking it prevents accidental callbacks if the number is reused.
Can callback scammers be traced?
Callback scammers deliberately use spoofed or temporary numbers to avoid tracing, as seen with 03 9003 8407 and 0390038407. However, reports to ACMA and Scamwatch help authorities identify patterns and track down scam networks over time. Your report about 03 9003 8407 contributes to broader investigations into callback fraud affecting Australians.
