Fair questions

What this can and can’t do

Does Scammer Checker tell me if something is safe?

No. It looks for common warning signs and tells you what it found. If nothing matches, the result reads "Unable to establish trust", because no match is not evidence that a message is legitimate. Only the real organization can confirm that, through contact details you found yourself.

Where does the text I paste go?

Nowhere. The checker runs inside your browser. What you paste is not sent to a server, not saved on your device, and not included in any analytics. Close the tab or press "Clear my check" and it is gone.

Do you open or scan the links I paste?

No. We read the link as text and show you its parts, including the registrable domain that decides where it leads. We do not visit it, follow redirects, or scan for malware, so a short link stays unverified.

Is this an AI?

No. Results come from a published set of written rules, each with a plain explanation and a source. The same input always gives the same result. You can read how it works on the How it works page.

Can I look up a person, a phone number, or a business?

No. Despite the name, this is not a lookup of people. It does not verify anyone's identity, run background checks, or search phone numbers. It looks at the message, link, or call you describe and points out common scam warning signs, so you can decide how to check through a source you trust.

Is a report here an official fraud report?

No. Reports sent to us help us describe new patterns for other readers. To report fraud in the U.S., use ReportFraud.ftc.gov, and IC3.gov for internet crime.

Who runs this?

Scammer Checker is an independent educational project from Sideroad. It is not a government service, an antivirus product, or an identity monitoring service, and it cannot guarantee your safety.
