Silent Call Report for 04 2369 7820
One contributor has reported receiving a silent call from 04 2369 7820 (also written as 0423697820). The caller disconnected immediately after the call was answered, leaving no message or indication of intent. This type of call is often associated with callback scam tactics, where callers test whether a number is active before attempting to contact it again with a scam pitch.
The call came from an Optus mobile number, which means it may be a personal phone rather than a business line. However, scammers frequently use legitimate mobile networks to make outbound calls, so the provider alone cannot determine whether this was a legitimate contact attempt.
What Silent Calls from 04 2369 7820 Indicate
Silent calls where the caller hangs up immediately upon connection are a recognised warning sign. They serve several purposes in scam operations: testing active numbers for callback scams, random testing of dialled numbers, or probing before a more targeted follow-up attempt. The contributor's experience with 0423697820 matches this pattern.
What to Do If You Receive a Call from 04 2369 7820
If 04 2369 7820 calls you:
- Do: Let it go to voicemail if you don't recognise the number
- Do: Block the number if calls continue
- Do: Avoid returning the call, especially if you don't recognise it
- Don't: Answer and confirm your voice is active if you don't know the caller
- Don't: Return a call from this number immediately - if it's legitimate, they will leave a voicemail or message
- Don't: Share any information if you do connect with someone claiming to be from this number
If the same number keeps calling and hanging up, blocking is the most effective response. Most phone providers allow you to block numbers through your device settings or carrier services.
Callback Scam Risks
Silent calls from numbers like 04 2369 7820 are sometimes used as part of callback scams. The tactic works like this: scammers call many numbers, hang up immediately, and hope people will be curious enough to call back. When you call the number, you may be connected to a scammer impersonating a government agency, utility provider, or financial institution. By that point, they control the conversation and can request personal information or payment.

WRITE A REVIEWFrequently Asked Questions
Why would someone call 04 2369 7820 and hang up immediately?
Silent calls that disconnect upon answering are commonly used to test whether a phone number is active and being answered by a real person. Scammers use this tactic to validate numbers for callback schemes, where they hope you'll be curious enough to call back. The contributor's experience with 0423697820 shows this exact pattern.
Should I call back a number like 04 2369 7820 if I missed the call?
No. If you don't recognise 04 2369 7820 and it rang only briefly with no message, calling back is risky. This is exactly what callback scammers hope you'll do. If the call was legitimate, the caller will leave a voicemail or try again. Returning the call puts you at risk of being connected to a scammer pretending to represent a bank, government agency, or utility.
Is 04 2369 7820 definitely a scam?
One contributor reported a silent call from 0423697820, but this alone doesn't prove it's a scam number. However, the behaviour - hanging up immediately - is a known tactic used in callback scams. The safest approach is to avoid returning the call and to block it if it calls repeatedly.
Can I block 04 2369 7820 on my phone?
Yes. Most Australian mobile phones allow you to block incoming numbers through settings. On iPhone, you can block under Settings > Phone > Blocked Contacts. On Android, most phones let you block under Phone > Call Settings > Block Numbers. You can also ask your carrier (Optus, in this case) to block 0423697820 for you.
What should I do if 04 2369 7820 keeps calling?
Block the number using your phone's built-in blocking feature. If the calls persist or escalate to messages, report the activity to ACMA (acma.gov.au) and your mobile provider. You can also report it on Reverseau to add to community records about 0423697820.
How is 04 2369 7820 connected to Optus?
The number 0423697820 is registered to Optus Mobile, meaning it's allocated as a mobile number under Optus infrastructure. However, this doesn't guarantee the person using it is Optus staff. Scammers can use legitimate mobile networks to make calls. The silent call pattern reported for 04 2369 7820 is consistent with impersonation or callback tactics rather than official Optus contact.
