Impersonation Scam Reports for 02 8529 5713
Three contributors have flagged 02 8529 5713 (also written as 0285295713) for impersonation scams targeting personal financial information. The pattern involves callers falsely claiming to represent major financial institutions or tech support services, attempting to exploit uncertainty about account status or device security.
Reports about 0285295713 indicate callers use minimal identifying information, typically providing only a first name like "Anna" when questioned about their organisation. This vague identification is a hallmark of impersonation scams designed to prevent verification and reduce accountability.
What Callers from 02 8529 5713 Claim
One contributor received a call from 02 8529 5713 where the caller claimed to represent Mastercard Security. The contributor had no Mastercard account, yet the caller still pursued the conversation. When asked directly where she was calling from, the caller provided minimal detail, offering only a personal name rather than the organisation name.
A separate report describes callers from 0285295713 posing as tech support representatives, claiming non-existent internet issues requiring immediate remediation. Contributors noted the callers affected Indian accents, a tactic commonly used in tech support impersonation schemes targeting Australian households.
A robocall voicemail from 02 8529 5713 was left in Mandarin Chinese, suggesting automated or semi-automated calling campaigns targeting multilingual populations. This type of activity is consistent with mass scam operations rather than legitimate business outreach.
Report Patterns and Timing
The three reports span nearly two years, with the most recent Mastercard impersonation call arriving in March 2026. The earlier robocall voicemail in July 2025 and the tech support impersonation report from January 2024 suggest this number has been used for multiple scam variants over an extended period.
The diversity of impersonation tactics (financial institution, tech support, and automated robocalls) reported from the same Sydney-based local number indicates either compromised infrastructure or deliberate abuse of legitimate service allocation.

WRITE A REVIEWFrequently Asked Questions
Why did a caller claiming to be Mastercard Security call about 0285295713 when I don't have a Mastercard?
A contributor reported receiving this exact scenario from 02 8529 5713. Scammers often call random numbers claiming financial issues exist regardless of whether you hold that account. They rely on creating urgency or confusion to bypass your initial scepticism. If you don't hold an account with the company they claim to represent, it's a strong indicator of impersonation fraud.
Is 02 8529 5713 a legitimate Mastercard number?
No. Mastercard's official customer service number is different from 0285295713, and the caller from this number would not be able to verify account details that don't exist. If you ever need to contact Mastercard, use the number on your card statement rather than returning a call from 02 8529 5713.
What does it mean if I get a robocall voicemail from 02 8529 5713 in another language?
A contributor reported receiving a robocall voicemail in Mandarin Chinese from 02 8529 5713. This is typical of automated scam campaigns targeting multilingual populations. Do not return the call, do not click any links, and report it to the ACMA. Legitimate organisations always contact you in your nominated language and provide clear contact details.
Should I worry if 02 8529 5713 claims to be tech support for my internet?
Yes. A report describes callers from 0285295713 posing as tech support claiming non-existent internet issues. Legitimate tech support calls about genuine problems are rare, and they will never call unsolicited claiming faults you haven't reported. Always contact your actual internet provider using the number on your bill if you suspect a real issue.
Why does the caller from 02 8529 5713 only give their first name?
A contributor noted the Mastercard impersonation caller from 02 8529 5713 would only provide the first name "Anna" and avoided stating which organisation she represented. This is a red flag for impersonation scams. Legitimate customer service representatives always clearly identify their company and department before discussing accounts.
Where is 02 8529 5713 registered?
The number 0285295713 is allocated as a local service in New South Wales through Symbio Networks Pty Ltd. However, allocation does not guarantee legitimacy. Scammers frequently use compromised or spoofed numbers from legitimate service providers, so the location is not a safety indicator.
