Community reports for 03 9003 3383 (0390033383): Callers impersonate Telstra claiming security risks, request account details, hang up when questioned.
Telstra Impersonation Reports for 03 9003 3383
Two contributors have reported calls from 03 9003 3383 (also written as 0390033383) claiming to represent Telstra. Both reports indicate callers used impersonation tactics to create urgency around alleged service or security issues. The pattern suggests a coordinated attempt to extract account information or direct victims to malicious websites.
What distinguishes these calls from legitimate Telstra contact is the caller behaviour when questioned. Contributors who asked for verification details or account confirmation found the caller on 0390033383 disconnected abruptly, a red flag indicator of social engineering rather than genuine customer service.
What Callers from 03 9003 3383 Claim
The first report about 03 9003 3383 describes a caller claiming a general service issue with the contributor's Telstra account. The caller provided minimal detail before hanging up, and when the contributor questioned the call, the caller made an unusual claim that the recipient was 15 years old - an apparent attempt to confuse or manipulate the conversation.
A second contributor received a call from 0390033383 with a more sophisticated social engineering approach. The caller claimed an IP address security risk and explicitly instructed the recipient to search for information on Google. This tactic is designed to make the threat appear legitimate by encouraging independent verification, before the caller presumably directs the victim to a malicious or lookalike website. When the contributor on the receiving end of the call from 03 9003 3383 refused to provide account details, the caller ended the call.
Report Patterns and Timing
Both reports for 03 9003 3383 came through answered calls rather than voicemail or SMS. The reports were submitted several weeks apart (December 2025 and February 2026), suggesting either recurring calls from this number or multiple targets. The brevity of both interactions - callers disconnected when resistance was encountered - indicates these are not extended social engineering attempts but rapid-fire probing calls designed to identify vulnerable recipients quickly.

WRITE A REVIEWFrequently Asked Questions
Is 03 9003 3383 a real Telstra number?
No. Community reports confirm 03 9003 3383 (0390033383) is used by scammers impersonating Telstra. The caller behaviour - hanging up when questioned and making confusing claims - proves this is not legitimate Telstra customer service. Real Telstra representatives will always verify your identity through your account number, not ask you to verify information they claim to have.
What should I do if I gave account details to a caller from 0390033383?
Contact Telstra immediately using the number on your bill or their official website. Do not use any number the caller from 03 9003 3383 provided. Inform Telstra of the call and ask them to review your account for unauthorised activity. Change your Telstra password and enable any available account security features.
Why did the caller from 03 9003 3383 tell me I was 15 years old?
This appears to be a confusion tactic. The caller's goal was likely to disorient you or suggest they had incorrect information, making the interaction seem less threatening so you might lower your guard. This is a social engineering technique. Real Telstra staff would never make such a claim - they verify identity through account details, not age guesses.
Should I Google the security issue the caller from 0390033383 mentioned?
No. This is a deliberate tactic reported in the 03 9003 3383 community reports. By instructing you to search online, the caller makes their threat appear independently verifiable, then directs you to visit a lookalike or malicious website. If you have genuine security concerns about your Telstra account, visit telstra.com.au directly in your browser or call Telstra's official number from your bill.
How do I block 03 9003 3383 on my phone?
On most Australian phones, you can add 0390033383 to your blocked contacts. iPhones: add the number to a contact, then Settings > Phone > Blocked Contacts. Android: Phone app > Recent > long-press the number > Block. Some carriers also allow you to block numbers through their apps (Telstra, Optus, Vodafone). After blocking 03 9003 3383, report it to ACMA and Scamwatch.
Why did the caller hang up when I asked for account details?
Scammers using 03 9003 3383 disconnect when they encounter resistance because their goal is to target vulnerable people quickly. They work through high call volumes, dropping calls from people who question them and moving to the next number. This behaviour - immediate disconnection rather than persistence or escalation - is a key indicator of impersonation fraud rather than legitimate customer service.
