NAB Impersonation SMS Scam Targeting 0483 642 064
A contributor received an SMS impersonating NAB on 21 October 2026, claiming an attempted Western Union transfer of $450.00 had occurred on their account. The message instructed the recipient to call 0483 642 064 to resolve the issue. This is a classic impersonation scam designed to trick NAB customers into calling a fraudulent number and potentially divulging sensitive banking information.
The scammer used the number 0483642064 as a callback contact within the SMS, creating false urgency around an unauthorised transaction. Real NAB security alerts will never ask you to call an unfamiliar number; they direct you to their official channels instead.
How the Scam Works
The SMS received from +918303885913 (an Indian number) references a specific transaction amount ($450.00 Western Union transfer) to appear legitimate. By including a recognisable amount and NAB's name, the message aims to alarm the recipient into immediate action. The inclusion of 0483 642 064 as the callback number is the scammer's hook - once you call, they can attempt to extract account details, passwords, or payment card information.
The contributor noted this was their third scam attempt in as many days, indicating an active targeting period for their contact details.

WRITE A REVIEWFrequently Asked Questions
Is 0483 642 064 a real NAB number?
No. 0483 642 064 is not a genuine NAB customer service number. NAB's official contact numbers are published on their website and your bank statements. If you receive an SMS referencing 0483642064 as a NAB contact, it is a scam. Never call numbers provided in unsolicited SMS messages.
What should I do if I already called 0483 642 064?
If you called this number and provided any personal information (account details, passwords, card numbers), contact NAB immediately on their official number to alert them. Change your online banking password and monitor your account for unauthorised transactions. You can also report the incident to Scamwatch at scamwatch.gov.au.
Why did I receive an SMS about a Western Union transfer I didn't make?
Scammers use specific transaction details (like the $450 Western Union transfer mentioned in the 0483 642 064 SMS) to create urgency and appear credible. They either guess common amounts or source your details from data breaches. The goal is to panic you into calling the fraudulent number 0483642064 before you can verify the claim independently.
Should I click the link in the SMS from 0483 642 064?
Absolutely not. Do not click any links in SMS messages claiming to be from NAB or other banks. Links in scam SMS often redirect to fake banking websites designed to steal your login credentials. If you receive such a message, delete it immediately and block the number 0483 642 064 (0483642064).
How do I know if a NAB SMS is genuine?
Genuine NAB security alerts will never include a phone number like 0483 642 064 or ask you to click a link. Real NAB messages direct you to use their official app, call the number on your card, or visit nab.com.au. If unsure, contact NAB directly using the contact details on your account or card - never use details from the SMS.
Can I report this number to stop receiving scam SMS?
You can report the SMS to ACMA by forwarding it to 0429 999 888. You should also block 0483 642 064 on your phone to prevent future messages. Report the scam on Reverseau and to Scamwatch so other Australians are aware. However, blocking individual numbers does not stop all scam SMS, as scammers frequently change numbers.
