NAB Impersonation SMS Scam - 212779855390

A contributor reported receiving a suspicious SMS from 212779855390 on 12 November 2026 around midday (WST). The message impersonated NAB's official SMS service, claiming to be a login verification code notification. The text stated: "NAB: Your login verification code is 37420. Don't share this code. If this was not you, contact customer service: 61 2 9099 5847"

The scammer sent the same message twice in quick succession from 212779855390, a common tactic to increase the likelihood of the recipient responding or clicking embedded links. The contributor had not initiated any login attempt, making the message clearly fraudulent.

How This NAB Impersonation Works

The SMS from 212779855390 used a technique known as OTP (one-time password) code interception or spoofing. By mimicking NAB's legitimate communication style and referencing a specific verification code, the scammer aimed to trick the recipient into either:

• Replying with the code or personal details
• Calling the fake customer service number provided (61 2 9099 5847)
• Clicking any embedded link to enter banking credentials

The inclusion of a fake customer service number is particularly dangerous, as callers may unknowingly hand over sensitive banking information, passwords, or personal identification details to the scammer operating the number.

Legitimate banks such as NAB have strict protocols for sending verification codes. Important differences between real NAB SMS and the fraudulent message from 212779855390:

• NAB will never ask you to share a verification code via SMS or phone call
• Real NAB messages do not include a customer service number within the SMS itself (scammers add these to intercept calls)

• NAB's official SMS alerts come from registered short codes, not long number formats like 212779855390
