NAB Impersonation SMS Reports for 1300 940 841

A contributor has reported receiving an SMS from 1300 940 841 (also written as 1300940841) impersonating National Australia Bank (NAB). The message contained a security code and explicitly instructed the recipient not to share it with anyone, including NAB staff. The contributor flagged the request as suspicious, noting the number is registered to a different address in Landsdale, WA, which doesn't align with legitimate NAB communications.

This type of SMS impersonation is a known phishing tactic where scammers attempt to harvest security codes or personal authentication credentials. The instruction "do not share with anyone including NAB" is a red flag, as legitimate banks never ask customers to withhold information from their own staff.

What Callers from 1300 940 841 Say

The SMS purporting to be from NAB included a security code and a warning not to disclose it to anyone. This phrasing mimics genuine bank communications but inverts the legitimate safety message. Real NAB security alerts would never instruct you to hide information from NAB itself. The contributor's instinct that the message "smells fishy" reflects the inconsistency in the request.

The use of 1300 940 841, a local-rate number serviced by multiple telcos, allows scammers to create a semblance of legitimacy. The registration to a residential address in Landsdale, WA rather than a business entity further supports the fraudulent nature of the communication.

Report Patterns and Timing

This report was submitted on 10 November 2025 via SMS channel. While only one contributor has reported 1300 940 841 to date, the specificity of the NAB impersonation and the detail provided about the registration address suggest the contributor conducted basic due diligence before reporting. The fact that the number is registered to a private address in WA, combined with a message requesting sensitive banking information, indicates organised phishing activity rather than random spam.

What to Do If You Receive an SMS from 1300 940 841

If 1300 940 841 sends you an SMS claiming to be from your bank:

• Do not: Reply to the message, click any links, share security codes or OTP (one-time passwords), or provide personal or banking information
• Do: Delete the message immediately, block the number, and contact your bank directly using the phone number on your bank card or official website
• Do: Report the SMS to your mobile provider and to ACMA
• Do: Check your bank account and credit report for unauthorised activity

Legitimate banks never request security codes via SMS and never instruct you to hide information from bank staff. Any message asking you to keep a code secret from your own bank is almost certainly a scam.
