Suspicious Call Pattern for 03 9003 3677
A contributor has flagged calls from 03 9003 3677 (also written as 0390033677) as suspicious based on coordinated calling behaviour. The report indicates two calls within an hour from 03 9003 3677 and a nearly identical number (03 9003 3679), neither of which left voicemail messages. The sequential numbering and timing suggest a deliberate pattern rather than coincidental contact attempts.
The caller behaviour of contacting from multiple similar numbers without leaving messages is typical of scam or spam operations testing which numbers are active. This tactic helps fraudsters identify working phone numbers for follow-up targeting.
What to Do If You Receive a Call from 03 9003 3677
If 03 9003 3677 calls you:
- Do not: Answer calls from unknown numbers, return the call, or engage if you do pick up
- Do: Let it go to voicemail, check if a legitimate message is left, block the number immediately if no message appears
- Do: Be alert for follow-up calls from similar numbers like 0390033679 - block these as well
The lack of voicemail is a red flag. Legitimate callers leave messages explaining the purpose of their call. If 03 9003 3677 or related numbers keep calling without messages, blocking them prevents further contact attempts.
Report Patterns and Silent Calls

Why would someone call from two similar numbers like 03 9003 3677 and 03 9003 3679?
Sequential number calling is a common tactic used by scam operations and automated dialling systems to test which phone numbers are active and connected to real people.

Should I report 03 9003 3677 to ACMA?
Yes. While one contributor's report of 03 9003 3677 (0390033677) is limited data, the silent calling pattern warrants reporting to ACMA at acma.gov.au.

Is 0390033677 a scam or spam number?
Based on the contributor's report, 03 9003 3677 exhibits suspicious characteristics: silent calls from sequential numbers with no voicemail. However, a single report limits definitive classification.
