Telstra Impersonation Reports for 03 9003 6506

Four contributors have reported calls from 03 9003 6506 (also written as 0390036506) with a consistent pattern of suspicious behaviour. Two reports specifically identify callers claiming affiliation with Telstra, with both callers disconnecting immediately when the contributor questioned their purpose or validity. The remaining reports describe silent calls where 0390036506 rings and disconnects when answered, typical of telemarketing screening tactics.

The impersonation angle is particularly concerning. Contributors report that callers from 03 9003 6506 stated they were from Telstra but provided no reason for the call before hanging up, suggesting either an automated system testing for active numbers or a scammer checking response patterns before escalating to a follow-up contact.

What Callers from 03 9003 6506 Say

Both impersonation reports follow an identical script: the caller identifies themselves as being from Telstra. One contributor noted that the moment they questioned why the person was calling, the line went dead. Another contributor reported a similar experience with a woman claiming to represent Telstra, who hung up immediately when asked to explain the purpose of the call.

This behaviour differs markedly from legitimate Telstra contact. Genuine Telstra representatives typically begin calls with a specific service issue or account query. The immediate disconnection when challenged strongly suggests the callers were either testing the validity of the number or attempting to establish a pattern of contact before running a more elaborate scheme.

Call Patterns and Timing

Reports spanning from late February to early April 2026 show sporadic contact from 03 9003 6506. One call came through at 02:47 AM, which is highly unusual for genuine telecommunications customer service. The pattern suggests either automated systems cycling through number lists or a campaign testing responses at off-peak hours when contributors might be more vulnerable or less cautious.

Two of the four reports about 0390036506 involved the silent call and immediate hang-up behaviour, which is commonly used to verify active phone numbers for scam lists. This technique increases the likelihood that 03 9003 6506 may attempt contact again with a different approach once a number is confirmed active.
