Suspicious Activity Reports for 03 9967 9806

Two contributors have flagged 03 9967 9806 (also written as 0399679806) for concerning calling behaviour. One report describes a caller claiming to conduct market research, requesting participation in a brief survey about economic conditions. The contributor noted the call sounded suspicious, suggesting the market research cover may have been pretextual. A second report from a different contributor documents a callback scam pattern where 0399679806 rings twice and immediately disconnects, a known tactic designed to prompt return calls to an unfamiliar number.

The number is allocated as a local service in Victoria through NetSIP Pty Ltd, but the pattern of reported behaviour suggests it may be operating outside legitimate business use.

What Callers from 03 9967 9806 Claim

The contributor who answered the call from 03 9967 9806 reported the caller claimed to be conducting market research and requested participation in a 10-question survey about the economy. According to the report, the caller's tone and approach felt suspicious to the recipient, raising doubt about the legitimacy of the stated purpose.

The second report documents a different calling pattern from 0399679806: the number rings exactly twice and hangs up before the recipient can answer. This behaviour is characteristic of callback scams, where automated diallers trigger incomplete calls to provoke curiosity or concern, encouraging recipients to call back. When recipients return the call to 0399679806, they may be connected to premium-rate numbers, charged per minute, or exposed to follow-up scam conversations.
