About Scam Number List
An explainer of common government impersonation phone scams and how to report them.
Why this exists
The Federal Trade Commission's Consumer Sentinel Network receives more than two million complaints per year, and the largest single category is impostor Scams — calls in which someone pretends to be from a government agency. The losses are enormous, and the calls follow a small handful of well-rehearsed scripts. Scam Number List was built to help people recognize these scripts quickly, in the moment a suspicious call comes in.
What this site covers
We focus exclusively on impersonation calls — IRS, Social Security Administration, Medicare, USPS, FBI, immigration enforcement, court systems, state revenue agencies, and Treasury. Telemarketing, debt-collection robocalls and political messages are out of scope; there are excellent directories for those elsewhere. By staying narrow we can explain each one properly: which agency the caller pretends to be, which script they use, and the tactic they use to apply pressure.
What we don't do
Scam Number List is not affiliated with any government agency. We do not make outbound calls. We do not sell phone numbers and we do not run paid takedown services. Everything on the site is publicly visible and free to read.

Directory removed
On 2026-09-18 this site removed its telephone-number directory: 1,200 pages that named individual phone numbers as scam callers, and the area-code pages that listed them. Those pages showed report counts, risk scores and quoted caller scripts that this site had no records behind. The FCC complaint figures shown under Call Trends are real and come from the FCC Consumer Complaints (Unwanted Calls) open dataset, which counts complaints by state and by call type and does not identify individual numbers.
