Check a number
Enter a number. Bewary checks it against FTC and FCC scam and robocall complaints and its scam lists.
Sources
Complaints consumers filed with the FCC and FTC, Oct 2, 2025 to Oct 31, 2026. Bewary counts the reports and does not check each one. Scammers can fake the number that shows on your phone, so a reported number may belong to someone who never called you.
