Impersonation Scam Reports for 03 7053 1504
Nine contributors have reported calls from 03 7053 1504 (also written as 0370531504) involving impersonation of major Australian service providers. The pattern is consistent across reports: callers falsely claim to represent Telstra, Amazon, or Vodafone, then either request sensitive information like one-time passwords (OTP) or ask probing questions to establish legitimacy before hanging up when challenged.
Four separate reports about 0370531504 specifically mention impersonation tactics, with three reports describing scam attempts and one describing a longer campaign of repeated calls. The callers appear to be targeting customers by referencing accounts or activities the recipients actually use, suggesting they possess customer data from previous breaches or purchased lists.
What Callers from 03 7053 1504 Claim
Contributors who answered calls from 03 7053 1504 report callers making several false claims. One contributor received a call claiming to be from Amazon regarding an unauthorised iPhone purchase, with the caller specifically requesting an OTP code. Another contributor was told by someone claiming to be from Telstra that their IP address had changed and needed to be verified. A third received a call from someone claiming to represent Vodafone who asked confusing questions and hung up when told the contributor didn't have service with them.
A notable report from December 2025 indicates multiple calls from numbers starting with 03 7053, claiming affiliation with both Telstra and Amazon, with no voicemails left. This suggests a systematic calling pattern across the 03 7053 number range rather than isolated incidents affecting 0370531504 alone.

WRITE A REVIEWFrequently Asked Questions
Why is 03 7053 1504 claiming to be from Telstra or Amazon?
Scammers use impersonation because it creates false trust. When a caller claims to be from a company you actually use, you're more likely to engage and provide information. Multiple reports about 0370531504 show callers falsely claiming to represent Telstra, Amazon, and Vodafone. These companies have large customer bases, making it statistically likely the call will reach someone who is actually a customer. The callers may possess customer data from breaches or purchased databases, allowing them to reference real account details to sound legitimate.
Should I provide an OTP code if 03 7053 1504 claims to be from my bank?
No. One report about 03 7053 1504 (0370531504) specifically involved a caller claiming to be from Amazon requesting an OTP for an iPhone purchase the contributor didn't make. Legitimate companies never ask for OTP codes via unsolicited calls. If you receive such a request from 03 7053 1504 or any number, hang up immediately and call your bank or service provider directly using the number on your card or official website to verify the request.
Why do some calls from 03 7053 1504 disconnect after ringing twice?
One contributor reported receiving four calls over three weeks where the number rang twice then disconnected. This pattern, combined with another report of repeated silent voicemails, suggests two possible tactics: testing whether the number is active and connected to a person, or using a callback scam strategy where you're prompted to call back a premium number. Do not return calls to 0370531504 or similar numbers that disconnect unexpectedly.
How do I know if a call claiming to be from Telstra on 03 7053 1504 is legitimate?
Multiple reports describe calls from 03 7053 1504 falsely claiming to be from Telstra. Legitimate Telstra calls can be verified by hanging up and calling Telstra directly on 133 200 (the official customer service number) using a phone other than the one that received the call. Never provide account details, passwords, or OTP codes during an unsolicited call. Contributors who questioned the callers from 0370531504 received suspicious responses and the callers disconnected.
What should I do if I already gave personal information to a caller from 03 7053 1504?
Contact your bank, telco, and the company the caller claimed to represent immediately. Report the incident to Scamwatch (scamwatch.gov.au) and ACMA (acma.gov.au). If an OTP was provided, change your passwords immediately and enable two-factor authentication on all accounts. Monitor your accounts for unauthorised activity. Block 0370531504 in your phone to prevent further contact from this number.
Are all calls from numbers starting with 03 7053 the same scam?
One December 2025 report mentions receiving 5 or 6 calls from multiple numbers starting with 03 7053, with callers claiming to be from Telstra or Amazon but never leaving messages. This suggests the scam operation may be using multiple numbers within the 03 7053 range. While 03 7053 1504 (0370531504) is the specific number with documented impersonation reports, remain cautious of other similar numbers. Report all suspected scam calls to ACMA and block them in your phone.
