Verisoul Phone Intelligence is a phone number validation and intelligence service designed to detect fraudulent accounts and prevent multi-accounting. The service validates user phone numbers in real-time and provides detailed information about each number. The platform identifies VoIP numbers, shared phone lines, and high-risk phone numbers that may be associated with fraudulent activity. It validates caller name identity to ensure the person using the phone number matches the registered owner. Phone Intelligence is part of Verisoul's broader account fraud detection platform, which helps organizations prevent repeat sign-ups, fake accounts, spam, scammers, and bot accounts. The service analyzes phone number characteristics to assess risk levels and detect patterns associated with fraudulent behavior. The tool integrates with Verisoul's other fraud detection capabilities including device fingerprinting, account linking, bot detection, email intelligence, proxy and VPN detection, device risk assessment, geolocation, face match, and ID check features. Organizations can use Phone Intelligence during user registration, account verification, and authentication processes to ensure phone numbers are legitimate and associated with real users rather than automated systems or fraud operations.
