Coinbase Impersonation Scam Reports for 03 5775 6937
Two contributors have reported scam activity from 03 5775 6937 (also written as 0357756937), with one specifically detailing a Coinbase impersonation attempt. The caller claimed to be from Coinbase and referenced a suspicious sign-in alert allegedly from New Zealand, creating urgency to prompt immediate action. This number is registered as a local service on the Optus network in Victoria.
The pattern suggests a coordinated phishing operation where callers impersonate legitimate cryptocurrency platforms to manipulate targets into compromising their accounts. One contributor noted they nearly fell for the scam before recognising the deception.
What Callers from 03 5775 6937 Claim
According to reports about 0357756937, the caller impersonates Coinbase support staff and references unauthorised sign-in attempts, typically claiming activity from unusual locations like New Zealand. This creates artificial urgency designed to bypass normal caution. The caller then directs the target to call the number 03 5775 6937 or click a phishing link, positioning themselves as the legitimate contact for account recovery.
The tactic exploits the natural panic people feel when their cryptocurrency accounts appear compromised. By combining impersonation with a seemingly legitimate security concern, the scammer aims to extract login credentials, two-factor authentication codes, or payment information before the victim can verify through official Coinbase channels.
Report Patterns and Timing
Both reports of calls from 03 5775 6937 originated from Victoria. One contributor received a call directly and answered, while the other proactively called the number and discovered the scam during the interaction. This suggests the number operates both inbound and receives return calls from confused targets. The reports span recent weeks, indicating the scam line remains active.

WRITE A REVIEWFrequently Asked Questions
Is 03 5775 6937 really from Coinbase?
No. Coinbase will never call you unsolicited about security alerts. If you receive a call from 03 5775 6937 claiming to be Coinbase, it's a scam. Coinbase communicates through email and in-app notifications only. Log into your actual Coinbase account directly (not through any links provided by the caller) to check for legitimate security alerts. If 0357756937 calls you, hang up immediately.
What should I do if I clicked a link from 03 5775 6937?
Act immediately. If you clicked a link from 03 5775 6937, your device may be compromised. Do not enter any login credentials or personal information. Change your Coinbase password immediately from a secure device using the official Coinbase app or website. Enable two-factor authentication if not already active. Monitor your accounts for unauthorised transactions. Consider contacting your bank if you shared financial details. Report the number to cyber.gov.au.
Why do scammers use 0357756937 instead of calling from Coinbase's real number?
Scammers use legitimate-looking local numbers like 03 5775 6937 to appear trustworthy and increase the chance you'll answer. They impersonate Coinbase because cryptocurrency users are accustomed to handling sensitive account access. The Victoria-based registration through Optus makes the number seem authentic. Never trust caller ID alone. Always verify by contacting companies directly using numbers from their official websites, not numbers provided during unsolicited calls.
How did scammers get my phone number for the call from 03 5775 6937?
Scammers obtain phone numbers through data breaches, purchased lists, or random dialling campaigns. The fact that the caller from 03 5775 6937 referenced a sign-in attempt from New Zealand suggests they may have accessed leaked credential databases that included email addresses linked to your phone. Do not assume they have complete information about you. If you're concerned, change passwords across all financial and cryptocurrency accounts and monitor your credit reports.
What makes the 03 5775 6937 scam convincing?
The call uses several manipulation tactics. First, it references a real security concern (unauthorised sign-in from New Zealand). Second, it creates urgency - forcing you to act quickly before 'attackers' drain your account. Third, it impersonates a company you may actually use. Fourth, it provides a phone number (03 5775 6937 / 0357756937) to 'help' you, making the scam seem official. The combination is designed to bypass critical thinking. Always verify security alerts independently.
Should I call 03 5775 6937 back to confirm it was a scam?
No. Do not call 0357756937 back under any circumstances. Returning the call may result in you being transferred to a scammer who will attempt to steal your credentials or payment information. Calling back also confirms your number is active, which may result in more scam calls. If you want to verify a security alert, only log into Coinbase directly through the official app or website, never through numbers provided by unsolicited callers.
