Community reports for 02 4003 5583 (0240035583) describe repeated missed calls with no messages and callback attempts revealing spoofed caller ID.
Repeated Calls from 02 4003 5583
Three contributors have reported activity from 02 4003 5583 (also written as 0240035583), a local service number registered in NSW. The consistent pattern involves repeated calls with no voicemail left behind, raising questions about the caller's intent.
Two recent reports describe identical behaviour: the number calls twice in succession during late evening hours, then hangs up without leaving a message. Contributors who received these calls from 02 4003 5583 remained uncertain about the source, as no identifying information was provided.
Callback Attempts and Spoofed Caller ID
One contributor took the step of calling 0240035583 back, only to receive a recorded message with an American accent stating the number was not in service. This finding strongly suggests caller ID spoofing, where the actual caller is masking their true number behind 02 4003 5583.
The use of spoofing technology makes it impossible to determine the legitimate source of calls from this number. When someone returns a call to 02 4003 5583, the disconnect between the recorded message and the spoofed caller ID indicates the number is being misused rather than operating as a legitimate local service.
Timing and Pattern of Calls
Both recent reports about 02 4003 5583 occurred during late night hours, when many people are less likely to answer. The back-to-back calling pattern observed by contributors suggests automated dialling or deliberate repeated contact attempts. One report was submitted today, indicating this activity remains ongoing.
The lack of voicemail messages across all reports is notable. Legitimate callers typically leave contact details or explain their purpose if reaching an answering machine. The silence from 0240035583 callers suggests they may be testing whether the number is active rather than attempting genuine communication.
What to Do If You Receive a Call from 02 4003 5583
If 02 4003 5583 calls you:
- Do not: Answer if you don't recognise the number, return the call, or engage with any recorded message
- Do: Let it go to voicemail, block the number immediately if calls repeat, and note the time of calls for your records
- Be aware: Callback attempts may not reach the actual caller due to spoofing, so avoid returning the call
- Monitor: If you receive multiple calls from 02 4003 5583 over consecutive days, this strengthens the case for reporting

WRITE A REVIEWFrequently Asked Questions
Why would someone spoof 02 4003 5583 instead of using their real number?
Spoofing a local NSW number like 02 4003 5583 (0240035583) makes the call appear more legitimate and increases the chance recipients will answer. Scammers and automated dialling services use spoofing to hide their identity and avoid being traced. The fact that callbacks to 02 4003 5583 reach a 'not in service' message confirms the number is being misused rather than operated by the actual caller.
If I call back 02 4003 5583, will I reach the person who called me?
No. One contributor who called back 0240035583 received a recorded American-accented message saying the number was not in service. This confirms the caller was using a spoofed ID. Calling back 02 4003 5583 will not connect you to the actual caller, and may waste your time or expose your number to further dialling attempts.
Is the back-to-back calling pattern from 02 4003 5583 a sign of scam activity?
The repeated-call pattern reported for 0240035583, combined with no message being left, suggests automated or deliberate harassment rather than legitimate business contact. Genuine callers typically leave voicemail explaining their purpose. The fact that 02 4003 5583 calls twice in succession with silence indicates the caller is testing activity or attempting to pressure you into answering.
Why do late-night calls from 02 4003 5583 happen when I'm less likely to answer?
Timing calls to 02 4003 5583 outside business hours (late evening, early morning) is a deliberate tactic to catch people off-guard or when they're less alert. Contributors reported receiving calls from 0240035583 during late-night hours with no message, which is common behaviour for scam operations, spam campaigns, or number-testing bots that operate across time zones.
Should I block 02 4003 5583 after one call, or wait for a pattern?
If you receive even one call from 02 4003 5583, blocking is reasonable given the spoofing and repeated-call reports. However, if you've received multiple calls from 0240035583 over consecutive days matching the pattern described (late night, back-to-back, no message), blocking is essential. Report to ACMA at acma.gov.au first to create an official record.
Is 02 4003 5583 a legitimate NSW business number that's been hacked?
While 0240035583 is registered as a local service in NSW through Symbio Networks, the spoofing evidence suggests the legitimate number holder (if any active business uses it) is not the source of these calls. The fact that callers receive an 'out of service' message when they call back 02 4003 5583 indicates the spoofing is persistent. This could mean the number is no longer in active use, has been abandoned, or is being deliberately exploited by scammers.
