Visa Impersonation Reports for 02 8004 9621
One contributor has reported a scam call from 02 8004 9621 (also written as 0280049621) involving impersonation of Visa. The caller falsely claimed to represent Visa and attempted to gather personal information while questioning the recipient about bitcoin transactions. This type of impersonation targets payment card holders by creating urgency around unauthorised activity.
What the Caller from 02 8004 9621 Did
The contributor reported that the caller from 0280049621 posed as a Visa representative. The call specifically focused on bitcoin transactions, suggesting the scammer was either attempting to verify if the recipient had made cryptocurrency purchases or to trick them into believing fraudulent activity had occurred on their account.

WRITE A REVIEWFrequently Asked Questions
Why would a scammer impersonate Visa and ask about bitcoin?
Scammers impersonating 02 8004 9621 may be testing whether you recognise cryptocurrency activity as suspicious, or they may be gathering information to access your accounts. Bitcoin questions also help them identify tech-savvy targets or those already involved in crypto who might be more easily persuaded. The personal information they collect can be used for identity theft or account takeover.
Is 0280049621 a real Visa number?
No. The number 02 8004 9621 is registered as a local service on Symbio Networks in NSW, not as an official Visa contact line. Visa's official customer service numbers are listed on your card or at visa.com.au. Never trust phone numbers provided by unsolicited callers claiming to be Visa.
What should I do if I already gave information to 02 8004 9621?
If you shared personal details with a caller from 02 8004 9621, contact your bank and Visa immediately to flag potential fraud. Monitor your accounts for unauthorised transactions. Consider placing a fraud alert with your credit provider and check your credit report. Report the call to Scamwatch at scamwatch.gov.au.
Can I block 0280049621 from calling again?
Yes. Add 02 8004 9621 to your phone's blocked contacts list. Most Australian carriers also allow you to report spam numbers through their apps or customer service. If 0280049621 continues to call after blocking, report it to ACMA at acma.gov.au.
Why do scammers ask about bitcoin specifically?
Bitcoin and other cryptocurrencies are often targeted by scammers because transactions are irreversible and harder to trace than traditional banking. A caller from 02 8004 9621 mentioning bitcoin may be testing your familiarity with crypto or setting up a secondary scam. Legitimate Visa representatives will never ask about your cryptocurrency activity.
Should I call the number back to verify it's really Visa?
No. Never call back a number claiming to be from Visa, especially 0280049621. Instead, use the official Visa number on your card or visit visa.com.au. Calling back a scam number confirms your contact is active and may expose you to further scams.
