Impersonation Scam Reports for 08 9921 5003
Four contributors have reported suspicious activity from 08 9921 5003 (also written as 0899215003), a Western Australian local service number allocated to Telstra Limited. Two reports specifically document impersonation attempts where callers falsely claimed to represent major financial and telecommunications organisations.

A separate report describes a caller claiming affiliation with a telecommunications company, though the contributor immediately recognised the call as illegitimate.

Call Patterns and Timing

Two were missed calls with no voicemail left. One contributor noted that when they called back the number from 08 9921 5003, they received a 'User Busy' tone, consistent with number spoofing. Another report documented the number calling four times in succession before ceasing contact, suggesting automated dialling patterns.
What to Do If You Receive a Call from 08 9921 5003
If you receive a call from 08 9921 5003 (0899215003) claiming to represent a financial institution, telecommunications provider, or government agency, do not engage with the caller. Hang up immediately. Do not confirm your identity, provide account details, or discuss financial information.
Verify the legitimacy of any urgent claims by contacting the organisation directly using a phone number from their official website or your bank statement, not a number the caller provides.

If the caller claims an account or service issue, visit the official website independently and contact them through verified channels.
If the number continues calling, block it on your phone and report the activity to the authorities listed below.

WRITE A REVIEWFrequently Asked Questions
Why would a caller claim to be from Visa or Mastercard when calling from 08 9921 5003?
Impersonating major financial networks increases perceived legitimacy and urgency. Contributors reporting 0899215003 noted the false claims were meant to create immediate concern about account security, making recipients more likely to engage before verifying the caller's identity. Always remember that Visa and Mastercard do not cold-call consumers about account issues.
What does 'User Busy' mean when calling back 08 9921 5003?
One contributor reported receiving a 'User Busy' tone when calling back the number. This is consistent with number spoofing, where a scammer masks their actual number with a fake one. The fake number may be disconnected, non-functional, or deliberately configured to prevent callbacks. Do not attempt to call back 0899215003 or any unknown number; simply block it.
Is 08 9921 5003 definitely a scam number because it's allocated to Telstra?
The number is a legitimate Telstra local service number, but this does not guarantee legitimacy of incoming calls. Scammers regularly spoof actual business numbers or compromise legitimate numbers through hacking. The community reports indicate that callers from 08 9921 5003 made false claims about who they represented, not that Telstra itself is responsible. Report the activity to ACMA and your service provider.
Why did the caller from 0899215003 hang up after multiple attempts?
One contributor reported the number called four times in quick succession, then stopped. This pattern suggests automated robocall dialling or a predictive dialler testing whether the line was active. Once the system detected a human connection, it may have moved on to the next target, or the campaign may have been paused. Block the number to prevent further contact attempts.
Should I reply or engage if 08 9921 5003 calls and claims to be from my bank?
No. Hang up immediately without providing any information. Banks and payment networks do not cold-call customers about security issues. Legitimate financial institutions contact you through verified channels and will never request passwords, PINs, or full account details over the phone. If you're concerned about your account, hang up and call your bank directly using the number on your statement or their official website.
Can I report calls from 08 9921 5003 to the Do Not Call Register?
The Do Not Call Register (donotcall.gov.au) is primarily for unwanted telemarketing. Scam calls like those reported for 0899215003 are better reported to Scamwatch (scamwatch.gov.au) and ACMA (acma.gov.au), which investigate deceptive and fraudulent activity. You can report to all three, but prioritise ACMA for impersonation and fraud.
