Spam Reports for 03 9003 1642
One contributor has reported persistent unwanted calls from 03 9003 1642 (also written as 0390031642). The pattern involves repeated calls that are not being answered or returning voicemail messages. What stands out in this report is the mention of similar numbers calling as well - the contributor notes variation in the final digit, suggesting a potential calling campaign using sequential or related phone numbers.
The activity has been ongoing for approximately three weeks, indicating this is not an isolated incident but rather a coordinated calling pattern. The fact that 0390031642 leaves no messages suggests the caller is not attempting genuine contact but rather testing whether the number is active or monitored.
Call Pattern and Behaviour from 03 9003 1642
The contributor's experience with 03 9003 1642 reveals a key characteristic of low-effort spam operations: the calls are silent, with no attempt to communicate a message or leave a voicemail. This behaviour is typical of automated calling systems or campaigns designed to identify active phone numbers for later targeting.
The mention of related numbers with single-digit variations calling the same person suggests a batch-calling approach. This is common in spam and scam operations that use number generation techniques to maximise reach across similar number ranges. The three-week duration indicates persistence rather than accidental repeated dialling.

WRITE A REVIEWFrequently Asked Questions
Why does 03 9003 1642 keep calling without leaving messages?
The caller from 03 9003 1642 appears to be testing whether your number is active rather than attempting genuine contact. This is typical of automated spam systems. Silent or message-free calls are a signature of batch-calling campaigns designed to identify monitored numbers for later targeting or resale.
Should I call back the number 0390031642?
No. Do not return calls to 0390031642 or any unknown number that calls without leaving a message. Returning the call confirms your number is active and monitored, which can increase future spam. Instead, block the number in your phone settings.
What does it mean that similar numbers are calling with one digit different?
When 03 9003 1642 is part of a pattern where similar numbers with single-digit variations are also calling, this indicates an automated calling campaign using sequential number generation. The caller is reaching out across a number range to identify active phones. This is common in high-volume spam operations.
How long should I wait before reporting 0390031642 to authorities?
If 03 9003 1642 continues calling after you block it, report immediately to ACMA at acma.gov.au. You don't need to wait - persistent unwanted calls are grounds for a complaint, especially if they've been happening over weeks as reported by this contributor.
Will blocking 03 9003 1642 stop calls from the similar numbers mentioned?
Blocking 0390031642 will stop that specific number, but if other similar numbers are calling you, you'll need to block those individually as they appear. Register your number on the Do Not Call Register at donotcall.gov.au for broader protection against telemarketing campaigns.
Is this spam or a scam from 03 9003 1642?
Based on the report, 03 9003 1642 appears to be spam rather than an active scam attempt - the calls leave no message and seem designed to test whether your number is monitored. However, if the calls escalate to messages, demands, or impersonation, the classification could change. Report any escalation to Scamwatch at scamwatch.gov.au.
