02 3815 7599 (0238157599): Contributors report NAB impersonation scam with aggressive behaviour, plus silent calls. NSW local number.

Bank Impersonation Reports for 02 3815 7599

Two contributors have reported suspicious activity from 02 3815 7599 (also written as 0238157599), a NSW local number. One report describes a caller impersonating National Australia Bank (NAB), claiming there was an unauthorised international transaction on the recipient's account. When questioned about why NAB would initiate contact rather than using official channels, the caller became aggressive, using abusive language before hanging up. Another report from this number involved complete silence with no message or caller identification.

The combination of NAB impersonation paired with silent calls from 0238157599 suggests this number may be part of a broader scam operation testing numbers and refining social engineering tactics. The aggressive response to questioning is a red flag indicator of a fraudulent caller, as legitimate banks never resort to abuse when verifying caller identity.

What Callers from 02 3815 7599 Claim

The contributor who answered the call from 02 3815 7599 reported the caller claimed to represent NAB and referenced a specific concern: an unauthorised international transaction. This is a common social engineering tactic because international fraud is a legitimate concern for account holders, creating urgency and emotional pressure to act quickly.

When the recipient asked a reasonable verification question-why NAB would be calling unsolicited rather than the account holder logging into online banking or calling NAB's official number-the caller's response was aggressive and abusive rather than professional. Genuine bank representatives have protocols for verification and remain courteous even when challenged. The immediate escalation to hostility is characteristic of scammers who cannot verify legitimacy and resort to pressure tactics.

Call Patterns from 02 3815 7599

Two separate calls were reported from 0238157599 within a five-day period (20-25 February 2026). One call was answered and resulted in the NAB impersonation attempt; the other was a silent call with no message. This pattern of mixed call types from the same number suggests automated dialling combined with manual scam attempts, a common approach used by scam operations to maximise call volume and identify viable targets.
