Suspicious Reports for 03 9559 6621
Two contributors have flagged calls from 03 9559 6621 (also written as 0395596621) as suspicious or scam-related. The reports indicate callers claiming affiliation with Optus and referencing mobile phone disconnection. This Telstra-allocated number based in Victoria has generated enough concern for contributors to report the activity on Reverseau.
What Callers from 03 9559 6621 Say
When one contributor returned the call to 0395596621, they heard a recorded message stating 'Optus advises that this mobile phone has been disconnected'. This type of response raises red flags, as it combines a major telco name (Optus) with a disconnection claim-both common elements in scam tactics designed to create urgency or trick recipients into providing personal information or payment details.
Another contributor simply reported 03 9559 6621 as a scammer without elaborating on the specific message or claim, suggesting the call itself was suspicious enough to warrant flagging.
Report Patterns
Both reports came through answered calls, meaning contributors actually picked up when 03 9559 6621 rang. One contributor took the extra step of returning the call, which revealed the pre-recorded Optus message. This behaviour-calling back an unknown number to verify legitimacy-is exactly what some scammers rely on, as it confirms the number is active and the person is a responsive target.
What to Do If You Receive a Call from 03 9559 6621
If 03 9559 6621 calls you:
- Do not: Return the call, provide personal information, share banking or device details, or act on any disconnection claim without verifying independently
- Do: Hang up immediately, contact Optus directly using the official number on their website or your bill if you're concerned about your account, and block the number if it calls again
- Verify independently: If the caller claims to represent Optus, do not use any contact details they provide. Instead, visit optus.com.au or call Optus directly on 133 937 to confirm any account issues

WRITE A REVIEWFrequently Asked Questions
What should I do if 03 9559 6621 calls and claims my Optus mobile is disconnected?
Do not provide any information or follow their instructions. Hang up immediately and contact Optus directly using the official number 133 937 from your bill or the Optus website (optus.com.au). Legitimate service providers do not contact you via unexpected calls claiming your account has been compromised or disconnected without you initiating contact. Never call back a number that claims to be from Optus after an unsolicited call-use only official contact details.
Why is returning a call to 0395596621 risky?
When you return a call to an unknown number like 0395596621, you confirm to scammers that your number is active and you are willing to engage. This makes you a higher-value target for future scam attempts. In this case, one contributor returned the call and heard a pre-recorded Optus disconnection message, which is a social engineering tactic designed to alarm you and prompt action (like providing payment details or personal info).
Is 03 9559 6621 definitely Optus?
No. While the message callers play from 0395596621 claims to be from Optus, the number itself is allocated to Telstra Limited in Victoria. Scammers regularly impersonate major telcos like Optus by playing recorded messages or spoofing caller ID. Always verify telco claims independently by contacting the provider directly on the official number from your bill or their website.
What if I already provided information to a caller from 03 9559 6621?
Contact your bank and Optus immediately on 133 937 to report the incident. If you provided banking details, credit card information, or passwords, ask your bank to flag your account for fraud. You can also report the call to Scamwatch (scamwatch.gov.au) and the ACMA (acma.gov.au). Consider enabling two-factor authentication on any accounts if you haven't already.
Should I block 0395596621?
Yes. If 03 9559 6621 calls you again, block it immediately on your phone. Most smartphones allow you to block numbers directly in your contacts or call history. You can also contact your provider (Telstra, Optus, Vodafone, etc.) to request call filtering services that block known scam numbers.
How many people have reported 03 9559 6621?
Two contributors have reported 0395596621 on Reverseau so far. Both flagged it as suspicious or a scam based on the claims made during the calls. If you receive a call from this number, please report your experience to help other Australians stay safe.
