Robocall Scam Reports for 0423 215 339
A contributor has reported receiving an automated robocall from 0423 215 339 (also written as 0423215339). The message claimed the recipient's number was expiring and prompted them to press 1 for English or 2 for Mandarin. This type of recorded message delivery combined with false urgency about account expiration is a known scam tactic designed to panic recipients into taking immediate action.
The allocation data shows 0423215339 is registered as a mobile number with Optus Mobile Pty Limited. The use of a standard mobile number format to deliver automated scam messages suggests the number may have been spoofed, compromised, or reassigned from a legitimate account.
What the Automated Message Says
The robocall from 0423 215 339 uses a threat-based approach, falsely claiming the recipient's number is expiring. By presenting a language selection prompt (English or Mandarin), the caller creates an interactive element designed to confirm the number is active and engaged, which can then be used for follow-up scam attempts or sold to other scammers.
The "expiring number" claim is not legitimate. Australian mobile numbers do not expire simply from inactivity, and legitimate service providers contact customers through verified channels using their registered contact details, not unsolicited robocalls from unfamiliar numbers.
Call Timing and Pattern
The report of 0423 215 339 was received in April 2026. With only one report at this stage, the frequency and time-of-day pattern of calls from this number are not yet fully established. However, the robocall format itself indicates this is likely an automated campaign that may repeat across multiple numbers and recipients.

WRITE A REVIEWFrequently Asked Questions
Is my phone number really expiring if I receive this robocall from 0423 215 339?
No. Australian mobile numbers do not expire from inactivity. The expiring number claim in the 0423 215 339 robocall is false. Legitimate telcos contact customers through verified channels (email, SMS, or phone calls using their known number) and do not use unsolicited robocalls from unfamiliar numbers to claim urgency. If you have genuine concerns about your account, contact your service provider directly using the number on your bill, never a number from an unsolicited call.
What happens if I press 1 or 2 when 0423215339 calls?
Pressing any button on the 0423215339 robocall confirms your number is active and monitored, making you a confirmed target for follow-up scam attempts. Scammers sell this information or use it to escalate to phishing calls impersonating your bank or government. Do not press anything - hang up immediately or let it go to voicemail.
Why did 0423 215 339 ask for English or Mandarin?
The language selection prompt from 0423 215 339 serves two purposes: it creates a false sense of legitimacy (as if a large organisation is calling) and it forces interaction that confirms the number is active. Some scammers also target multilingual communities with translated phishing messages. Either way, it's a scam tactic - do not engage.
Can I trust that 0423 215 339 is from Optus because it shows up as an Optus number?
No. The 0423215339 number is registered to Optus, but robocalls using this number do not necessarily originate from Optus. The number may have been spoofed (faked in caller ID), compromised, or the SIM reassigned. Always verify by calling your provider directly using the official number on your bill, never using contact details from an unsolicited call.
Should I call back 0423 215 339 to confirm the message?
No. Do not call back 0423215339. Calling back confirms your number is active and monitored, and may connect you to scammers who will attempt to extract personal or financial information. If you have concerns about your mobile service, contact Optus directly using the number on your bill or their official website, not the number that called you.
Where can I report the 0423 215 339 robocall in Australia?
Report 0423 215 339 to ACMA (acma.gov.au) and Scamwatch (scamwatch.gov.au) with the date, time, and message details. Also notify Optus directly at optus.com.au or through their customer service to report the compromised number 0423215339.
