Callback Request Reports for 0408 738 549
Two contributors have reported activity from 0408 738 549 (also written as 0408738549), a Telstra mobile number. The most specific report describes a callback scam tactic where the caller claimed to have dialled the wrong number, then immediately asked the recipient to send a WhatsApp message. This is a known social engineering technique designed to establish contact via a harder-to-trace messaging platform.
One additional report flagged 0408738549 as a suspected scam without elaborating on specifics, suggesting contributors recognise this pattern as problematic even in its early stages.
What Callers from 0408 738 549 Say
According to the report, the caller from 0408 738 549 opened with a classic pretext: claiming they had reached a wrong number. Rather than simply ending the call, they then pivoted to a direct request: asking the recipient to contact them via WhatsApp. This two-step approach is characteristic of callback scams, where initial contact is made by phone but the scammer attempts to move the conversation to a platform they control more completely.
The use of WhatsApp specifically is significant. Unlike phone records, WhatsApp conversations are encrypted and harder for authorities to trace, and the platform's mobile-first design makes it easier for scammers to operate accounts without full identity verification.
Report Patterns and Timing
The most recent report about 0408 738 549 came in early January 2026 via a call the contributor answered. This suggests the number is actively being used for outbound contact attempts. The callback request variant represents a mid-tier scam sophistication level: more targeted than robocalls, but relying on social engineering rather than elaborate impersonation.
What to Do If You Receive a Call from 0408 738 549
If 0408 738 549 calls you:
- Do not: Respond to requests to contact via WhatsApp, Telegram, or other messaging apps; share any personal information; return the call if you miss it
- Do: Hang up immediately if the caller claims wrong number then asks you to reach out; block the number on your phone; report the activity to authorities if you engage further

WRITE A REVIEWFrequently Asked Questions
Why would a scammer ask me to contact them via WhatsApp after claiming a wrong number?
The callback request tactic exploits your willingness to help and creates a sense of legitimacy from the initial phone contact. By moving to WhatsApp, the scammer avoids phone records and can operate with more anonymity. The '0408738549 wrong number' pretext is a social engineering hook that makes you feel like you're helping, increasing compliance. Once on WhatsApp, they can request payment, personal information, or access to your accounts.
Should I ever contact someone back via messaging if they claim to have called me by mistake?
No. If 0408 738 549 or any unknown number claims they've reached you by mistake, simply end the call. Legitimate callers do not follow up misdials by requesting contact via third-party apps. Scammers use this approach specifically because it moves the conversation out of phone company logs and into platforms they control. If someone genuinely needs to reach you, they will either call back or you can look up their official number independently.
What should I do if I already replied to 0408738549 on WhatsApp?
Stop responding immediately and block the contact on WhatsApp. Do not share any additional personal information, bank details, or identity documents. Check your bank and credit accounts for suspicious activity. Consider reporting the WhatsApp account to the platform itself via their in-app reporting feature. You can also report the incident to Scamwatch (scamwatch.gov.au) and ACMA (acma.gov.au), as your experience helps identify active scam campaigns.
Is 0408 738 549 definitely a scam, or could it be a legitimate wrong number?
Community reports about 0408 738 549 describe a pattern consistent with callback request scams, not genuine misdials. A legitimate wrong number caller would apologise and disconnect. The fact that the caller immediately pivoted to requesting WhatsApp contact-after claiming an error-matches a known scam template. The second contributor's warning about 0408738549 being a scam adds to the pattern, though the Telstra mobile number format makes it possible the account was compromised or spoofed.
Could the caller have been using a fake version of 0408 738 549?
Yes, caller ID spoofing is possible. Scammers can make calls appear to come from any number, including legitimate Telstra mobile numbers. However, the pattern reported here-wrong number claim followed by WhatsApp request-is the actual scam mechanism, regardless of whether 0408738549 is a real account or a spoofed display. Either way, you should not engage with the request to contact via messaging apps.
How can I report this to my phone provider if the number is from Telstra?
Contact Telstra directly at 133 300 or via their online account to report the number 0408 738 549 as suspicious. Provide details of what the caller claimed and requested. However, your primary reports should go to ACMA (acma.gov.au) and Scamwatch (scamwatch.gov.au), as they track scam patterns across providers. If you received an SMS, forward it to 0429 999 888. Reports to multiple agencies help authorities identify networks of compromised or fraudulent numbers.
