Phone Reputation Service

The world’s largest and most accurate database of fraudulent phone numbers

The Definitive Source for Phone Fraud Number Lookup and Research

Pindrop Security’s Phone Reputation Service (PRS) is the world’s largest and most accurate database of fraudulent phone numbers. PRS assigns a unique risk score to every number and provides detailed information, including geography, phone type, and, if a fraud number, specific institutions targeted, attack frequency and other numbers used by the attacking entity. The PRS is accessed via an easy-to-use interface that displays a variety of fraud activities and trends, provides actionable intelligence on suspect numbers, and allows the creation of fraud alerts.
