How to check if a phone number is a scam

  1. 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.
  2. Search community reports for the number. Browse scam phone number reports — if other users have flagged the same number, it shows here.
  3. Verify through a contact you trust. The displayed number may be spoofed, and returning a call can reach the innocent owner of that number. Use the organisation's official app, website, bill, or your bank card to find the right contact.
  4. Block and report. In Australia, block the contact, tell your telco, and report the suspected scam to Scamwatch. For unwanted commercial SMS, the ACMA accepts forwards at 0429 999 888. Standard message charges apply; forwarding shares your number and the message content, which may include personal information, with the ACMA. In the UK or US, forward unwanted SMS to 7726 if your mobile provider supports it.

Red flags in scam calls and scam SMS

  • Caller ID matches a real bank or government agency. The number shown may be spoofed, so a familiar name or number does not authenticate the caller. End the call and use independently found official contact details.
  • "Move your money to a safe account." Banks do not ask customers to transfer money to a "safe account" or open a new account to protect funds. Stop and contact your bank independently.
  • "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." Threats of immediate arrest or police action unless you pay are strong scam signals. End the call and verify through the agency's official contact details.
  • "Press 1 to speak to an officer." Treat an unexpected recorded call that demands urgent action as suspicious. The recording format alone does not prove fraud, so verify independently.
  • An unexpected SMS payment link claiming to be from a courier, toll operator, tax agency, or bank is a reason to pause. Open the organisation's known app or website yourself instead.
  • A voicemail demanding an immediate callback is not proof that the caller is legitimate. Check any number against contact details published by the organisation.

Common scam call scripts the checker recognises

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. A number-only check searches available community reports and basic number signals. No matching report means the result is unknown, not that the caller is safe. Add the message or what the caller said for a fuller pattern check.

Is this scam call checker free?

Yes. Check a number or paste a message without signing up. Usage limits protect shared capacity; results show warning signs rather than proving caller identity or safety.

My bank is calling me from its real number — can I trust the call?

Caller ID alone cannot authenticate the caller because the displayed number may be spoofed. End the call and contact your bank through its official app or the number on the back of your card. Banks do not ask customers to move money to a "safe account".

Should I call back a missed call from an unknown number?

Avoid relying on the displayed number. It may be spoofed, so a callback can reach an innocent number owner. If the caller claimed to represent an organisation, find its contact details in an official app, website, bill, or card. A voicemail is not proof of identity.

Where do I report a scam phone number?

In Australia, report suspected scams to Scamwatch online. Block the contact and tell your telco. For unwanted commercial SMS, the ACMA accepts forwards at 0429 999 888. Standard message charges apply, and forwarding shares your number and message content with the ACMA. In the UK or US, check whether your mobile provider accepts unwanted SMS at 7726. For other reporting options, use your country's reporting body.
