Spam Reports for 03 9003 7851
Two contributors have reported suspicious activity from 03 9003 7851 (also written as 0390037851).

The silence on voicemail is a distinctive feature of these calls to 0390037851. When callers do not leave messages despite repeated contact attempts, it often indicates automated dialling systems or campaigns designed to identify active phone numbers rather than genuine contact attempts.
Caller Behaviour and Patterns
Contributors who received calls from 03 9003 7851 describe a pattern of missed calls without any attempt at communication. One report specifically mentions multiple calls from different numbers in the same range, suggesting the caller may be cycling through number variations. This behaviour is typical of spam or scam operations using predictive dialling systems that test number validity before connecting to an agent or playing a recorded message.
The fact that calls from 0390037851 and similar numbers in the sequence never include voicemail messages distinguishes this from legitimate business calls, which typically leave explanatory messages if the recipient does not answer.
What to Do If You Receive a Call from 03 9003 7851

- Do: Enable call filtering on your phone if available to reduce unwanted calls reaching you

WRITE A REVIEWFrequently Asked Questions
Why do callers from 03 9003 7851 never leave voicemail messages?
Contributors report that calls from 03 9003 7851 consistently lack voicemail, which is characteristic of automated dialling systems. These systems often call large numbers of people to identify valid phone numbers rather than connect with a live operator. Legitimate businesses almost always leave messages if they are trying to reach you. The absence of voicemail from 0390037851 strongly suggests an undesirable caller.
Is it normal to receive calls from multiple numbers with the same prefix as 03 9003 7851?
The pattern of calls from multiple numbers sharing the prefix 03 9003 but with different ending digits, as reported for 0390037851, is not normal for legitimate callers. Real businesses use consistent contact numbers. This behaviour indicates a spam or scam operation systematically testing number ranges, which is why blocking the entire sequence may be necessary.
What should I do if I keep getting calls from numbers like 03 9003 7851?
Start by blocking 03 9003 7851 on your phone. If you continue receiving calls from other numbers in the same range, block those as well. Enable call filtering if your phone supports it. Avoid answering or returning calls, as this confirms your number is active. Report the pattern to ACMA at acma.gov.au so they can track the campaign.
Could 03 9003 7851 be a legitimate business that forgot to set up voicemail?
Unlikely. Legitimate businesses, especially those making outbound calls, always ensure voicemail is configured or assign someone to answer calls. The combination of no voicemail and multiple calls from similar numbers (as reported for 0390037851) indicates an automated spam or scam operation rather than an oversight by a real company.
Should I report 0390037851 to the Do Not Call Register?
The Do Not Call Register (donotcall.gov.au) is designed to reduce telemarketing calls. However, it provides no protection against spam or scam operations, which typically ignore the register. If 03 9003 7851 is telemarketing, registration may help long-term. For immediate relief, block the number and report to ACMA at acma.gov.au, which has stronger enforcement powers.
Is there a risk to answering a call from 03 9003 7851?
There is minimal risk in simply answering a call from 0390037851, but there is a risk in what you do after. If you answer and a scammer asks for personal information, bank details, or payment, do not provide anything. If it is spam or an unknown caller, hang up immediately. The safest approach is to let unknown numbers go to voicemail and respond only if the caller identifies themselves clearly.
