How WhoCalledMe.ai works

Phone intelligence

Number type (mobile, landline, VoIP, premium), country and region, carrier, and line activity. VoIP and recently-allocated numbers carry higher base risk.

Community reports

User-submitted reports, including scam category and free-text descriptions. Velocity matters: a number with many reports in 48 hours is treated as higher-risk than the same total spread over a year.

Pattern matching

Known scam scripts, prefix-level campaign data (e.g. active Wangiri ranges), and spoofing indicators (mismatch between displayed and originating networks).

What the score isn't

It's not a guarantee. A low score doesn't make a call safe — a brand-new scam number has no history. A high score doesn't make every call from that number a scam — numbers get reassigned. Use the score to inform, not to decide.
