Robocall and phone scam checker
Americans received an average of 2.56 billion scam and telemarketing robocalls every month in 2025, a 20% increase over the prior year, and phone scams cost US consumers an estimated 12.5 billion dollars in 2024. Despite the FTC's National Do Not Call Registry covering over 253 million numbers and FCC enforcement actions against hundreds of carriers, 31% of American adults still receive at least one scam call every day. The most common schemes include IRS impersonation, fake tech support, Social Security fraud and package delivery scams.
