NAB Impersonation Reports for 03 9490 5800

Two contributors have flagged calls from 03 9490 5800 (also written as 0394905800) for suspicious impersonation activity. Both reports describe callers claiming affiliation with National Australia Bank (NAB), though the details and caller demeanour raised red flags for the recipients.

The first contributor who received a call from 0394905800 reported that the caller claimed to be from NAB, but something about the interaction "sounds a bit off." A second contributor received a similar call from 03 9490 5800 where the caller specifically mentioned the NAB Greensborough branch, yet the contributor remained uncertain about the legitimacy of the contact.

What Callers from 03 9490 5800 Claim

Both reports of 03 9490 5800 involve callers identifying themselves as representatives from NAB. One caller referenced the NAB Greensborough branch specifically, which may have been intended to add credibility. However, neither contributor was fully convinced of the caller's authenticity, suggesting the impersonation lacked convincing details or the caller's tone and behaviour raised suspicion.

The vague nature of the reports - where contributors sensed something was "off" rather than reporting specific demands or claims - indicates the callers may have been in early-stage contact attempts, possibly testing whether the recipient would engage before proceeding with a scam request.

Report Patterns and Timing

Both reports about 0394905800 came through answered calls within a short timeframe on 11 February 2026, suggesting a concentrated calling campaign. The calls were answered by recipients, meaning the callers did not rely on voicemail or SMS tactics, and instead attempted direct engagement.

The number is allocated as a local service via Telstra Limited in Victoria, which may lend false legitimacy to callers impersonating NAB or other Victorian-based organisations.
