NAB Impersonation Reports for 03 8903 0507
Ten contributors have reported activity from 03 8903 0507 (also written as 0389030507), with a significant pattern of impersonation. Three reports specifically describe callers claiming to represent National Australia Bank (NAB), requesting personal financial details during unsolicited calls. The number is allocated to Telstra Limited in Victoria and classified as a local service.
What distinguishes the reports about 0389030507 is the mixed legitimacy signal - two contributors verified genuine NAB contact, while three flagged the number as a confirmed scam.

What Callers from 03 8903 0507 Claim
Reports indicate callers from 03 8903 0507 use NAB branding as their primary approach. One contributor noted the caller "claimed to be from NAB" and asked about personal details. Another report describes a text from what was claimed to be a "NAB rep about loan check," followed by a call from the same number.
The persistence of contact stands out across multiple reports. One contributor received calls "at least twice a day for five days" along with accompanying SMS text. Another describes daily calls from 0389030507 where the caller "hung up when they started asking questions," suggesting they abandoned the approach when challenged. A third contributor mentions being contacted multiple times with claims about home loan status checks, noting these typically occur "near end of fixed-term rate" - language that mimics legitimate bank processes.
Loan-Related Contact Patterns
Beyond impersonation, several reports centre on unsolicited loan contact. One contributor explicitly states they had "already told them not to call about refinancing" yet continued receiving calls saying "they'll check in 6 months." This contributor expressed discomfort: "Don't feel safe talking about that on a cold call." Another report describes texts claiming to be about "a loan check," with the caller requesting verification of personal information during the subsequent phone call from 03 8903 0507.
The frequency and timing patterns differ across reports. One contributor received contact "called daily" with escalating personal info requests. Another experienced calls "twice a day for five days" clustered within a single week, suggesting targeting rather than random dialling.

WRITE A REVIEWFrequently Asked Questions
Is 03 8903 0507 a legitimate NAB number?
Not consistently. Two contributors verified genuine NAB contact from 0389030507, but three separate reports flagged it as a confirmed scam using NAB impersonation. The mixed signals suggest either a compromised number or spoofed caller ID. Always verify by hanging up and calling NAB directly on the number from your bank card, never using a number provided by the caller.
Why do callers from 0389030507 ask for personal details?
Reports indicate callers from 03 8903 0507 request personal and financial information under the guise of loan checks or account verification. One contributor noted the caller "asked about my details" during daily calls. This is a phishing tactic - legitimate banks already have your details and will never request account information during unsolicited outbound calls.
What should I do if 03 8903 0507 won't stop calling?
One contributor reported receiving calls "at least twice a day for five days" from 0389030507 with accompanying SMS messages. Block the number in your phone settings, do not answer or return calls, and formally register with the Australian Do Not Call Register at donotcall.gov.au. Report the persistent contact to ACMA at acma.gov.au if calls continue.
Can I trust a text claiming to be from NAB followed by a call from 0389030507?
No. One contributor received an SMS claiming to be from a "NAB rep about loan check" and then received a call from 03 8903 0507 three days later, describing the sequence as "pretty sure it's a scam." Scammers often use SMS to trigger follow-up calls. Never respond to unsolicited bank texts - contact your bank directly instead.
How did one contributor confirm 0389030507 was suspicious?
A contributor used True Caller (a caller identification app) which flagged 03 8903 0507 as a scam. When they called the number back, they received a NAB group message, which heightened their suspicion that the number was spoofed or misused. This cross-checking approach helped identify the threat despite the legitimate-seeming NAB connection.
What's a red flag if 0389030507 calls about my loan?
One contributor noted they were "already told them not to call about refinancing" yet the caller persisted saying "they'll check in 6 months." Legitimate banks respect opt-out requests. Also, do not discuss loans or confirm account details on cold calls from 03 8903 0507 - always hang up and verify through official NAB channels first.
