Report the number that called you
Thirty seconds of your time turns one annoying call into a warning for everyone who gets the next one. Reports feed straight into the risk level shown on every lookup.
How to read the result
Every lookup returns the same five signals. Together they answer the question faster than any single one of them.
- Line type. Mobile and landline numbers belong to real subscribers. VoIP lines are cheap, disposable and behind most scam and robocall campaigns.
- Carrier. A carrier that serves your region is a good sign. A carrier you have never heard of, paired with a VoIP line, is not.
- Location. Where the number was issued. A "local" number from a provider elsewhere means the caller ID was chosen to look familiar.
- Caller name. The name the carrier publishes, when there is one. Businesses and landlines usually have it; mobiles often do not.
- Risk. Fraud signals combined with community reports. Three or more reports raise the level; scam and robocall reports raise it fastest.
What to do next
High risk or scam reports: block the number, do not call back, and report it here. If money or data changed hands, file a complaint with the FTC at reportfraud.ftc.gov (US) or the Canadian Anti-Fraud Centre.
Low risk, real carrier, no reports: probably a person or business that did not leave a voicemail. Returning the call is usually fine.
Repeated calls from the same area code: check the area code page for that prefix. It lists the most-reported numbers and the scam scripts people are hearing right now.
Frequently asked questions
How do I find out who called me from this phone number?
Enter the number in the lookup panel. You will see the carrier, whether it is a mobile, landline or VoIP line, where it was issued and a risk level built from fraud signals and community reports. If you need a name, unlock the owner report.
Why does the caller ID show a local number but the call is a scam?
Scammers spoof local numbers because people answer them more often. A lookup reveals the real line: a VoIP number or a carrier that does not serve your area is the tell. Community reports on the same number confirm it.
Should I call back an unknown number?
Check it first. If the lookup shows a low risk level, a normal carrier and no reports, it is usually safe. If it shows a VoIP line, a high risk level or scam reports, do not call back; block the number and report it so others are warned.
Do my reports stay anonymous?
Yes. Reports show the number, the category and your comment. Your name, email and IP address are never displayed. Signed-in reports carry more weight in the risk score.
What if the number is mine or my business and it was reported by mistake?
Submit a "Safe" report with a short explanation, or contact [email protected]. We review disputed numbers and remove reports that are abusive or clearly wrong.
