Free Scam Phone Number Checker
Paste the phone number, the SMS text, or what the caller said. Our checker scans the content for the patterns scam callers actually use — fake bank fraud teams, ATO/IRS "arrest warrant" threats, fake delivery redelivery fees, and recorded robocalls.
We do not run live carrier lookup or caller-ID verification. If you only have a number with no context, search community reports below for matches.

How to check if a phone number is a scam
- Paste any message they sent you into the checker above. SMS, voicemail transcript, or what the caller said — the analysis flags urgency, impersonation, OTP harvesting, and lookalike links.
- Search community reports for the number. Browse scam phone number reports — if other users have flagged the same number, it shows here.
- Do not call back unknown numbers. Returning the call can confirm your number is live and trigger more scam attempts. Look up the organisation independently and call them on a number you trust.
- Block and report. Forward scam SMS to 7726 (UK, Australia, US carriers support this). In Australia, forward to
0429 999 888(Scamwatch).
Red flags in scam calls and scam SMS
- Caller ID matches a real bank or government agency. Caller ID is trivially spoofable. The fact that "CommBank" or "HMRC" appears means nothing.
- "Move your money to a safe account." No bank fraud team ever asks for this. It is the single most reliable tell.
- "Read me the code we just sent." OTP harvesting. Never share a one-time code with someone who called you, no matter who they claim to be.
- "An arrest warrant has been issued." Tax authorities (ATO, HMRC, IRS) do not send police over the phone. This is a script.
- "Press 1 to speak to an officer." Robocalls from government agencies are essentially always scams.
- SMS with a payment link from
+61 4xx,+44 7xxx, or a random international number claiming to be AusPost, Royal Mail, USPS, DHL, Linkt, the ATO, HMRC, or a bank. - Voicemail demanding immediate callback on a number that is not the official line for the organisation.
Common scam call scripts the checker recognises

Tax authority "arrest warrant"
"This is the ATO/HMRC/IRS. A legal case has been filed. Press 1 to speak to an officer or be arrested within 24 hours."
Tech support "Microsoft" call
"We can see hackers in your computer right now. Please install AnyDesk so we can clean it for you."
Recorded redelivery / customs fee SMS

Frequently asked questions
Can you look up who owns a phone number?
No. We do not run live carrier lookup, caller-ID verification, or reverse phone lookup. Numbers can be spoofed in seconds — caller ID is unreliable. The checker analyses the content of the message or call, which is far harder for a scammer to disguise.
Is this scam call checker free?
Yes. No sign-up, no limits, nothing stored. Paste the call transcript, the SMS, or what the caller said and read the result.
My bank is calling me from its real number — can I trust the call?
No. Caller ID is trivially spoofable. If you are not sure, hang up and call the number on the back of your card. A real bank will not pressure you, ask you to read back codes, or tell you to move money to a "safe account".
Should I call back a missed call from an unknown number?
Usually no. Calling back confirms your number is active and may flag you as a higher-value target. If it's urgent, the caller will leave a voicemail or text.
Where do I report a scam phone number?
In Australia, forward the SMS to 0429 999 888 (Scamwatch) and report to your country's reporting body. UK: Action Fraud. US: FTC Report Fraud. Most carriers also accept scam SMS forwarded to 7726.
