About this site
When a number you don’t know calls and something feels wrong, the first thing most people do is search for it. This site answers that search, free and in plain words: what other people reported about the number, and what to do next.
Who makes it
Is This Number a Scam? is made by PhoneShield, a service of Who Can It Be, LLC. PhoneShield answers phone calls before they ring: known scam numbers are refused, the people you know ring straight through, and unknown callers are asked who they are. We run this site as a free public resource, without ads.
Where the reports come from
The FTC’s Do Not Call complaints
People report unwanted calls to the Federal Trade Commission through the National Do Not Call Registry. The FTC publishes these complaints each weekday as open data: the number that called, the day, what the call was about and whether it was a robocall, without anything about the person who complained. We count them as published. The FTC does not verify complaints, and we can’t either. Our copy begins on September 18, 2026; earlier days are not counted.
PhoneShield’s front desk
When PhoneShield’s front desk answers a call for one of its customers and refuses it as a scam, that number’s page says so, with a short, general label for the kind of call it heard, such as a fake bank fraud alert. Never the words of a call, and never anything about PhoneShield’s customers.
Visitors to this site
Anyone can report a number they got a call or text from. A quick Cloudflare check confirms a person sent it, and each connection can report a number once a day. Visitor reports show on the number’s page as counts and categories, apart from the FTC’s complaints; notes are read only by us and never published. They don’t change a number’s report level below.
How a number’s report level is decided
- Reported often: 10 or more reports to the FTC in the last 30 days, or PhoneShield’s front desk refused a call from it as a scam.
- Some reports: 1 to 9 reports to the FTC in the last 30 days.
- No reports found: none in the last 30 days. That is not proof a number is safe.
- Ride or delivery app number: a number apps like Uber, Lyft or DoorDash use to connect drivers and couriers with customers.
A report level describes reports, not the person or business a number belongs to. Caller ID is easy to fake, and scammers often borrow real people’s numbers.
Which pages appear in search results
Only numbers with real reports behind them: five or more reports to the FTC in the last 90 days, or a scam verdict from PhoneShield’s front desk. Every other number still has a page, so a lookup always answers, but it is kept out of search results. A page also leaves search results the moment someone says it is their number, while we review it.
What we don’t do
- We don’t say who owns a number, and we don’t call anyone a scammer.
- We don’t publish what visitors write, and we don’t copy other sites’ lists.
- We don’t show ads or sell data. Our only analytics is Google Analytics; see the privacy notice.
