The Phone Risk Score evaluates whether a phone number behaves consistently with legitimate ownership and stable usage by analyzing ownership stability, behavioral patterns, and ecosystem signals across the network rather than just verifying that it is active. Key categories include:

Phone Type & Infrastructure: The type of number and its associated infrastructure, flagging VoIP or temporary services often used by fraud networks to create disposable contact points

Identity Rotation: How many identities the number has been linked to over time, where high churn may indicate synthetic identities or coordinated fraud

Geographic Consistency: Whether usage aligns with expected geographic stability, with inconsistencies signaling identity misuse or account takeover

Usage Patterns & Network Signals: Activity levels and submission velocity across applications and infrastructure, which can reveal automated submissions or organized fraud rings
