NAB Impersonation Reports for 03 8903 0505
Community reports for 03 8903 0505 (also written as 0389030505) reveal a complex pattern mixing suspected impersonation with occasional legitimate NAB contact. Three contributors have flagged this Telstra-provided Victorian number as impersonating National Australia Bank, while five others confirm receiving genuine NAB calls about home loans. The inconsistency itself is concerning: scammers often spoof or mimic bank numbers, and legitimate NAB customers have reported being unable to verify the caller's authenticity when questioned.
One contributor who answered a call from 03 8903 0505 stated the caller claimed to be from NAB but refused to provide any details to verify their identity before hanging up. When this contributor contacted NAB directly, the bank confirmed that 0389030505 was not their number. Another contributor received nine missed calls in a single week from this number, with five occurring on one day alone, prompting them to contact NAB who confirmed they were not calling from 03 8903 0505.
What Callers from 03 8903 0505 Say and Do
Reports about 03 8903 0505 consistently describe silent or non-responsive callers. Multiple contributors noted that when they answered, no one spoke before the line disconnected. One contributor described being put on hold after answering, only for the caller to hang up within seconds. Another received a call preceded by an SMS claiming to be from NAB, then answered to hear complete silence.
A contributor who received a robocall from 03 8903 0505 reported hearing a recorded robotic message claiming to be from NAB before the call disconnected. Several contributors also mentioned receiving SMS messages stating "NAB will call you about your home loan" minutes before receiving calls from 0389030505, though the timing and origin of these texts adds to the suspicion around this number.
Call Patterns and Frequency
One contributor reported receiving multiple calls from 03 8903 0505 on a monthly basis over an extended period. Another experienced an intensive cluster with nine missed calls within a single week, concentrated on one day with five attempts. The calls appear to occur at various times, including at least one early morning call (0630) to a work phone number not publicly listed, suggesting possible automated dialling or data breach sourcing.
Most reports about 03 8903 0505 came through missed calls, with several contributors choosing not to answer after the first or second attempt. Only a handful of contributors answered, and nearly all of those who did reported silent calls or immediate disconnections. The voicemail pattern is notable: despite frequent calling, contributors report that no voicemail messages are left, which is atypical of legitimate bank communication.
Legitimate NAB Activity Mixed Into Reports
Five contributors confirmed receiving legitimate calls from 03 8903 0505 related to home loan verification and banking services from National Australia Bank. These calls were answered, resulted in straightforward conversations, and were later confirmed as genuine NAB contact. This legitimate activity complicates interpretation: 03 8903 0505 appears to be a number NAB does use for outbound communications, but the number has also been misused or spoofed for impersonation attempts.
The mix of legitimate and fraudulent reports suggests either that scammers are spoofing this known NAB number, or that NAB's own systems have been compromised for some outbound campaigns. Contributors cannot reliably determine authenticity by the number alone, which is precisely what makes impersonation effective.
What to Do If You Receive a Call from 03 8903 0505
If 03 8903 0505 calls you:
- Do not: Answer if you don't recognise the number, provide personal or financial information, confirm account details, or trust caller ID alone
- Do: Let unknown calls go to voicemail, hang up immediately if the caller does not speak or is silent, call NAB directly using the number on your bank card or official NAB website to verify any claimed home loan discussions
- For silent calls: Block the number after the first or second occurrence, report to your phone provider if calls persist, do not return the call as callback scams use silence tactics to identify active numbers
- If you believe it's NAB: End the call politely and contact NAB through official channels (your bank card, statement, or nab.com.au) to confirm they were attempting to reach you

Pretending to be from my bank. But would not give any details with regards to his authenticity. I hung up saying you are a scammer.
Bombarded with 9 missed calls in a week, 5 in one day. Called NAB and they said this number isn't theirs. Total scam
I am a NAB customer and this number calls me multiple times a month. I answered the first time, and the caller did not speak, so since they enjoyed wasting my time I put them on hold and they hung up after a few seconds. The number continues to call me and I refuse to pick up, so voicemail is ever left. If this is really NAB, they act like scammers.
Was NAB checking in about home loans, not a scam
Left message about a home loan, seemed straightforward
I had 03 89039600 call at 0630 on my work phone, my work number is not linked or published so I am assuming a scan on rotary dial.
NAB reaching out to verify home loans, confirmed not a scam
Legit NAB number.
Legitimate call from NAB Banking Services, National Australia Bank
Yeah, this is weird, like the others I received a NAB text saying they would call and then 10 minutes later, the call. I answered but no one spoke, just hung up.
Was told via SMS that I woul get a call from NAB about my home loan. I didn't answer this and when I called back answering machine said to visit NAB to find where you need to call. Probably not a scam.
Might be from NAB because I received a text from “NAB” an hour prior to call but no one answered. A bit worrying. Most likely another scammer.
This number called my work. I called back and a recorded robotic message said it was from NAB and then it hung up.

WRITE A REVIEWFrequently Asked Questions
Is 03 8903 0505 actually NAB's number?
The situation is mixed. NAB does use 03 8903 0505 (0389030505) for legitimate outbound banking communications, particularly about home loans. However, multiple contributors report that when they contacted NAB directly, the bank confirmed they were not calling from this number at the time the calls were received. This suggests the number may be spoofed by scammers, or that NAB uses it inconsistently. Always verify by calling NAB back using the number on your bank card rather than returning a call to 0389030505.
Why do some calls from 03 8903 0505 have no one on the line?
Silent calls from 03 8903 0505 are a known scam tactic. Scammers use automated systems to dial large numbers and listen for signs of an active line. When someone answers, they either hang up immediately to confirm the number is active (selling it to other scammers), or stay silent to see how long you'll wait. One contributor who answered 0389030505 experienced this: the caller remained silent, and when put on hold, disconnected within seconds. Never stay on the line or return a silent call.
I received an SMS from NAB saying I'd get a call from 03 8903 0505. Is it safe?
Be cautious. Several contributors reported receiving SMS messages claiming to be from NAB minutes before calls from 03 8903 0505 arrived. While NAB does send SMS notifications about incoming calls, scammers can spoof SMS sender IDs to appear as NAB. If you receive such an SMS followed by a call from 0389030505, do not provide information over the phone. Instead, end the call and contact NAB directly using the number on your card to verify the communication was genuine.
Should I answer calls from 03 8903 0505?
Given the mixed reports about 0389030505, it's safest to let calls go to voicemail initially. Legitimate NAB communications will typically leave a message or you can verify through your online banking. If the caller claims to be from NAB but cannot verify their identity when questioned (as one contributor experienced with 03 8903 0505), that's a red flag. Genuine banks can always provide verification details before discussing accounts.
Why does 03 8903 0505 call work numbers and unpublished phone numbers?
One contributor reported receiving a call from 03 8903 0505 (0389030505) at 0630 on their work phone, which is not listed publicly. This suggests either that scammers have access to a broader database of contact information (possibly from a data breach), or they are using automated rotary dialling to cycle through number combinations. Either way, this behaviour is suspicious and inconsistent with how legitimate banks typically contact customers.
What should I do if 03 8903 0505 keeps calling me?
First, call NAB directly using the number on your bank card or visit a branch to confirm whether any calls from 0389030505 were legitimate. If NAB confirms they are not calling you, block the number in your phone settings. Report the calls to ACMA at acma.gov.au and to Scamwatch at scamwatch.gov.au. If 03 8903 0505 continues calling after blocking, document the dates and times and report again. Consider reporting to your phone provider (Telstra, as this number is allocated to them) and contribute your report to Reverseau.
