Coinbase Impersonation Reports for 03 5315 4256

Two contributors have reported scam activity from 03 5315 4256 (also written as 0353154256), a Victorian local service number. The pattern centres on impersonation of Coinbase, the cryptocurrency exchange platform, using both SMS and voice calls to trick recipients into revealing account credentials or clicking malicious links.

One contributor received an SMS from 0353154256 claiming to be from Coinbase with a verification code (844-756) and a request to contact the number if they didn't request it. This is a classic phishing technique designed to appear legitimate while actually creating urgency to respond to the scammer's contact number. Another contributor answered a call from 03 5315 4256 where the caller claimed to represent Coinbase but described the interaction as "dodgy," suggesting suspicious behaviour or unusual claims.

What Callers from 03 5315 4256 Claim

Based on community reports, callers from 03 5315 4256 impersonate Coinbase support staff. The SMS tactic uses fake verification codes to appear authentic, referencing a code that the recipient supposedly didn't request. This creates false urgency by implying unauthorized account access or suspicious activity, pushing the recipient to call the number back to "verify" their identity.

Contributors note the scammers reference real Coinbase processes (verification codes, account security) to increase believability. The inclusion of the phone number 0353154256 in the SMS itself is designed to make the message look official, as if Coinbase has included their contact method for verification purposes.

Report Patterns and Timing

Reports about 03 5315 4256 came in via multiple channels within a 24-hour period (23-24 December 2025).

The timing of reports suggests ongoing campaign activity rather than isolated incidents.
