One report describes a direct call where the caller claimed to represent NAB and requested credit card details. The second report notes persistent calling patterns from this number and related numbers in the Portland NSW area, with no voicemail messages left behind.
The impersonation tactic used with 02 5350 6807 is particularly concerning because it exploits trust in a major Australian financial institution. Bank impersonation attempts rely on creating urgency around account security or fraud, often combined with requests for sensitive financial information.
What Callers from 02 5350 6807 Claim
The contributor who answered the call from 02 5350 6807 reported that the caller specifically claimed to represent NAB and immediately requested credit card details. No legitimate bank will request sensitive payment card information over an unsolicited call.
The second contributor's experience with 0253506807 differs slightly - they received multiple calls but chose not to answer. Notably, no voicemail messages were left, which is a common pattern with automated calling campaigns or callers without legitimate business to conduct. The contributor also mentioned related calls from cousin numbers originating from Portland NSW, suggesting a coordinated campaign rather than isolated misdials.
Call Patterns and Timing
One call from 02 5350 6807 was answered on 6 February 2026, while the persistent calling pattern was reported on 30 January 2026.

The fact that multiple related numbers from the Portland area were also calling suggests this may be part of a broader calling operation rather than a single bad actor.

WRITE A REVIEWFrequently Asked Questions
Why would someone impersonate NAB when calling 02 5350 6807?
Bank impersonation is highly effective because it creates urgency and exploits trust in legitimate financial institutions. The caller from 02 5350 6807 claimed to represent NAB specifically because people are more likely to engage with a recognised bank name. Once trust is established, the caller requests sensitive payment details under the guise of verifying account information or preventing fraud.
Is 0253506807 definitely a scam number?
The allocation data shows 0253506807 is a legitimate local service number in NSW assigned to Symbio Networks Pty Ltd. However, phone numbers can be spoofed or used for scam campaigns. The reports about 0253506807 describe impersonation (claiming to be NAB) and persistent unwanted calls, which are hallmarks of fraudulent activity. Treat any unsolicited call from 02 5350 6807 claiming to be your bank as suspicious.
What should I do if I already gave credit card details to the caller from 02 5350 6807?
Contact your bank immediately using the number on the back of your card. Tell them you may have been compromised by a scam call from 02 5350 6807. Your bank can cancel your card, issue a replacement, and monitor for fraudulent transactions. Check your credit report through equifax.com.au or experian.com.au for unauthorised accounts opened in your name.
Why are there multiple related calls from Portland NSW numbers?
The second contributor mentioned calls from 02 5350 6807 and cousin numbers from Portland NSW, all leaving no voicemail. This pattern suggests a coordinated calling campaign rather than accidental misdials. Scam operations often use multiple related numbers to increase call volume and reduce the chance of being blocked entirely. If you're receiving calls from several numbers in the same area code, report all of them.
How can I verify if a call claiming to be from NAB is genuine?
Never verify bank calls by calling back numbers provided by the caller - they may be fake numbers controlled by the scammer. Instead, hang up and dial the number on the back of your NAB card or visit nab.com.au directly. Legitimate banks will never request credit card details, PINs, or CVV numbers over unsolicited calls. If you're unsure, ask the caller to provide a reference number and say you'll call the bank back yourself.
Can I report the calls from 02 5350 6807 if I didn't answer?
Yes, absolutely. The second contributor reported 0253506807 as suspicious based on repeated calls with no messages left. You can report this pattern to Reverseau, Scamwatch, and the ACMA even if you didn't answer. Include details like the frequency of calls, the time of day, whether messages were left, and any caller claims if you have any information. This helps build a record of calling patterns.
