Personal Information Request Scam from 0421 204 176
One contributor has reported a suspicious SMS from 0421 204 176 (also written as 0421204176) requesting sensitive financial information. The message asks the recipient to confirm via Yes or No whether they can deposit over $2,000 into another account, a classic tactic used to obtain both confirmation of the person's willingness to transfer funds and their banking details.
The SMS from 0421204176 was sent to a mobile number provisioned by Optus, suggesting the scammer may be targeting Optus customers or using data sourced from Optus breaches or purchased customer lists.
What the SMS from 0421 204 176 Contains
The contributor received a message asking them to reply Yes or No regarding a deposit of over $2,000 into a separate account. This style of message is designed to appear urgent and personal, creating a false sense of legitimacy by referencing a specific dollar amount.
The request for card details in the same message is a direct indicator of financial fraud. Legitimate financial institutions and services never request card details via SMS, and any such request should be treated as a scam attempt.
Why This SMS from 0421204176 Is a Red Flag
- Unsolicited financial request: The message asks for confirmation to transfer money without any prior context or account relationship
- Card details request: Legitimate organisations never ask for payment card details via SMS
- Yes/No confirmation trap: Replying Yes creates a false record the scammer can use to claim consent for unauthorised transfers
- Large amount specified: Mentioning over $2,000 suggests the scammer is targeting victims capable of significant financial loss

Financial scam SMS messages often follow predictable patterns: they create urgency, request confirmation of large transfers, and ask for sensitive information. Never respond to unsolicited financial requests via SMS, even if they appear to come from a known bank or organisation. Always verify requests independently by contacting the organisation directly using official channels.

WRITE A REVIEWFrequently Asked Questions
Should I reply Yes or No to the SMS from 0421 204 176?
No. Do not reply to the message from 0421204176 under any circumstances. Replying Yes or No can be used by scammers to claim you consented to a financial transfer, and it confirms your number is active and monitored by a real person - making you a target for further scam attempts.
Is 0421 204 176 a legitimate Optus number?
The number 0421204176 is allocated to Optus mobile, but this does not mean the SMS is legitimate. Scammers often use spoofed numbers or legitimate network allocations to appear trustworthy. Always verify requests directly with your bank or organisation using official contact details, never the number provided in an unsolicited SMS.
What should I do if I already replied to the SMS from 0421 204 176?
Contact your bank immediately and report the scam. If you shared any card details with 0421204176, request a replacement card. Monitor your account for unauthorised transactions and consider placing a fraud alert with your credit bureau. Report the number to ACMA (0429 999 888) and Scamwatch (scamwatch.gov.au).
Can I trust the message because it mentions a specific dollar amount like $2,000?
No. Scammers mention specific amounts to make the message appear more legitimate and personal. The fact that 0421 204 176 references $2,000+ suggests they've researched your financial capacity or are targeting high-value victims. Specificity is a manipulation tactic, not proof of legitimacy.
How do I block 0421204176 on my phone?
Most Australian mobile phones allow you to block numbers directly. On iPhone, open the message from 0421 204 176, tap the sender details, and select Block Contact. On Android, open the message, tap the three dots, and choose Block Number. After blocking 0421204176, also report it to your provider (Optus) and the ACMA.
Should I forward the SMS from 0421 204 176 to my bank?
Yes. Forward the message from 0421204176 to your bank's fraud team using the contact number on your official bank statement or website. Also forward it to ACMA by sending the SMS to 0429 999 888. This helps both your bank and the regulator identify emerging scam patterns and protect other customers.
