Phone scams cost victims worldwide over $12 billion in 2024, with most calls originating from a small number of high-risk country codes. The Federal Trade Commission (FTC) and FBI's Internet Crime Complaint Center (IC3) consistently link the same country codes to wangiri callbacks, advance-fee fraud, lottery scams, romance scams, and pig butchering. Knowing where a call comes from is the single fastest way to gauge whether it's safe to answer or call back.
DialCode tracks 19 high-risk country codes with detailed scam profiles: the specific fraud schemes operated from each region, warning signs to watch for, what to do if you've been targeted, and how to block calls at the carrier level. All content is sourced from public FTC, IC3, and Action Fraud reports - no speculation, no clickbait. If you've received a suspicious call, look up the country code below or use the search on the home page.
