Impersonation Scam Reports for 03 9003 1158
Two contributors have reported scam calls from 03 9003 1158 (also written as 0390031158) involving false claims of company affiliation. The reports indicate callers are impersonating legitimate service providers to gain trust and access to personal information or payment details.

What Callers from 03 9003 1158 Claim
Contributors report callers from 03 9003 1158 using company impersonation as their primary tactic. One caller falsely claimed to represent Telstra, a major Australian telecommunications provider. When the contributor questioned this claim and stated they had no Telstra account, the caller was told to "get lost"-suggesting the caller abandoned the approach when challenged.
A second report describes a different impersonation angle: the caller claimed expertise in computer security and stated that the recipient's computer was compromised. This type of claim typically precedes requests for remote access to the device or payment for fake repairs.

The two reports from 0390031158 span early to late March 2026. One call came through in the early morning (07:43), while the other arrived mid-morning (10:32). Both contributors answered the call, allowing them to identify the impersonation attempt directly rather than from voicemail or caller ID alone.
The rapid succession of reports about 03 9003 1158 suggests active calling patterns during a short timeframe, though the limited dataset prevents definitive conclusions about frequency or daily calling windows.

WRITE A REVIEWFrequently Asked Questions
What should I do if a caller from 03 9003 1158 claims I have a Telstra account problem?
Hang up immediately and do not engage with the caller. If you have a Telstra account and need to check its status, contact Telstra directly using the phone number on your bill or their official website-never use a number the caller provides. Contributors who received calls from 03 9003 1158 claiming Telstra affiliation were not actually customers, indicating the caller was using false claims to build credibility.
Why would someone call from 0390031158 claiming my computer is compromised?
This is a common scam tactic. Once they convince you your computer has a problem, they typically request remote access (which gives them control of your device) or demand payment for fake repairs. Legitimate technology companies like Microsoft and Apple never call unsolicited about computer problems. If you're concerned about genuine security issues, contact your computer manufacturer directly using their official support number.
Should I answer calls from 03 9003 1158?
It's safest to let unknown numbers go to voicemail. If you do answer 03 9003 1158 or 0390031158 and the caller makes unusual claims about your accounts or devices, hang up immediately without providing any information. The contributor who answered and questioned the Telstra claim was able to identify it as fake because they didn't have an account with that provider.
Is 03 9003 1158 a Telstra number?
No. While the caller claimed to represent Telstra, the 03 area code indicates the number is registered in Victoria. Telstra customer service lines use different published numbers. If you need genuine support from Telstra, use the contact details on your official Telstra bill or their website, never numbers provided by unsolicited callers.
What should I do if I gave information to a caller from 0390031158?
Contact the relevant organisation (bank, Telstra, etc.) immediately to report potential fraud and monitor your accounts for unauthorised activity. If you provided remote access to your computer, change all passwords from a different device and consider running antivirus software. Report the incident to Scamwatch at scamwatch.gov.au and ReportCyber at cyber.gov.au.
Can I block 03 9003 1158 on my phone?
Yes. Most Australian phones allow you to block numbers directly through your contacts or call history. You can also report the number to your service provider and request they block it at the network level. Additionally, register your number on the Do Not Call Register at donotcall.gov.au to reduce unsolicited telemarketing calls, and report 03 9003 1158 to ACMA at acma.gov.au to help authorities track scam activity.
