Suspicious Activity from 03 9003 1649
Two contributors have reported receiving calls from 03 9003 1649 (also written as 0390031649) that fit a pattern common to automated spam systems. In both cases, the caller did not leave a voicemail message after the call went unanswered. Phone systems have flagged 0390031649 as likely spam, suggesting the number has triggered automated detection algorithms.
This behaviour - calling but not leaving a message - is typical of robocalls, callback scams, or automated number verification systems used in spam campaigns. The lack of voicemail content makes it impossible to determine the caller's intent, but the repeated pattern across multiple contributors suggests systematic calling rather than a genuine attempt to reach individuals.
What to Do If You Receive a Call from 03 9003 1649
If 03 9003 1649 calls you:
- Do not: Return the call, answer if you don't recognise the number, or provide any personal information
- Do: Let it go to voicemail, block the number immediately, and do not call back
- Do: Note the time and date if the call repeats from 0390031649
If you receive repeated calls from 03 9003 1649 despite blocking it, the caller may be using callback scam tactics to verify your number is active. Do not engage with the number in any way.

WRITE A REVIEWFrequently Asked Questions
Should I answer if 03 9003 1649 calls me?
No. The two community reports for 03 9003 1649 (0390031649) both describe missed calls with no voicemail, which suggests the caller has no legitimate message to convey. Phone systems have flagged this number as likely spam. It's safest to let calls from 0390031649 go to voicemail and block the number.
Why does 03 9003 1649 call but not leave a message?
Robocalls and callback scams often use this tactic to verify that a phone number is active without attempting to deceive the caller. The call from 03 9003 1649 (0390031649) may be part of a system that automatically dials numbers and disconnects when someone answers or the call goes to voicemail. This data is then sold or used for future scam targeting.
Is 0390031649 a legitimate business number?
Based on community reports, 03 9003 1649 (0390031649) does not appear to be a legitimate business. Genuine businesses typically leave voicemail messages explaining the purpose of their call. The fact that callers from this number do not leave messages, combined with phone system spam flags, indicates this is likely an automated spam or scam operation.
What should I do if 03 9003 1649 keeps calling me?
Block the number immediately on your phone. If calls from 03 9003 1649 or 0390031649 persist despite blocking, report the repeated calls to ACMA at acma.gov.au and consider reporting to your phone provider. Do not attempt to return the call or engage with the number.
Can I report 03 9003 1649 to the Do Not Call Register?
The Do Not Call Register (donotcall.gov.au) helps reduce unwanted marketing calls, but it's not the primary tool for reporting individual nuisance numbers. For 03 9003 1649 (0390031649), your best options are ACMA (acma.gov.au) for spam calls and Scamwatch (scamwatch.gov.au) if you suspect scam activity.
