Unknown Caller Reports for 0424 539 920
A single contributor has reported receiving a call from 0424 539 920 (also written as 0424539920) where the caller answered but failed to identify who they were or why they were calling. This type of call can be unsettling, particularly when the caller remains silent or unresponsive after you answer.
The number is registered as a Vodafone Australia mobile, which means it could be any individual using that provider. Without identification from the caller, it's difficult to determine the purpose of the call or whether it poses any risk.
What Happened When the Call Was Answered
According to the contributor's report about 0424539920, they answered the call only to find the caller did not introduce themselves or explain the reason for their call. This behaviour is unusual in legitimate business communications, where callers typically identify their organisation and purpose immediately.
Silent or unidentified calls from 0424 539 920 may indicate:
- A wrong number dialled by accident
- An automated system that disconnected before playing a message
- A potential callback scam where the caller hangs up hoping you'll call back
- Someone testing whether the number is active

WRITE A REVIEWFrequently Asked Questions
Why would someone call from 0424 539 920 but not say who they are?
There are several possible reasons. The most common is a wrong number where the caller realised their mistake and hung up. However, unidentified calls can also be part of callback scams where the caller deliberately avoids identifying themselves, hoping you'll call back and incur charges. The contributor's report about 0424539920 describes exactly this type of behaviour - answering but remaining silent.
Is 0424 539 920 a scam number?
Based on the single report received, it's uncertain. One contributor reported receiving a call from 0424 539 920 where the caller did not identify themselves, which is suspicious but not conclusive proof of scam activity. A legitimate caller might have hung up accidentally, or it could be a wrong number. However, repeated unidentified calls warrant caution and possible blocking.
Should I call 0424539920 back?
It's not recommended. Calling back an unidentified number, especially one that didn't identify itself when they called you, can expose you to scam tactics like callback charges, premium numbers, or social engineering. Wait to see if 0424 539 920 calls again and leaves a message. If it's legitimate, they'll likely try again and provide proper identification.
What's a callback scam and how does 0424 539 920 fit?
In callback scams, scammers call your number, let it ring once or twice, then hang up. When you call back out of curiosity, you're connected to a premium-rate number that charges you significant fees. The contributor's report of 0424539920 showing a caller who answered but didn't identify themselves could fit this pattern, though one report isn't enough to confirm.
How do I block 0424 539 920 on my phone?
Most Australian mobile phones allow you to block numbers directly. On iPhone, open the recent call from 0424 539 920, tap the info icon, and select 'Block this Caller'. On Android, open your call history, find 0424539920, press and hold the entry, then select 'Block' or 'Add to reject list'. You can also report it to your Vodafone provider if the number belongs to them.
Should I report this number to ACMA?
If you receive repeated calls from 0424 539 920 where the caller doesn't identify themselves, yes - you can report it to ACMA at acma.gov.au. A single unidentified call might be accidental, but a pattern of behaviour suggests intentional calling. Provide details of when you received calls from 0424539920, how many times, and what the caller did or said.
