Phone Number Check screens a user’s phone number to validate authenticity and uncover identity signals tied to that number. This check can serve as a lightweight KYC entry point or a fraud flag signal in standard onboarding flows.

​
Core Features

  • Phone Validation: Confirms if the number is active, mobile or landline, and not disposable.
  • Carrier & Country Data: See which network and country are associated with the number.
  • Social Account Matching: Identify linked accounts (e.g. email, social profiles) tied to that phone.
  • Risk Score: Flags high-risk numbers based on telco behavior and public data.

​
Use Cases

  • User Onboarding: Validate a user’s number before proceeding with ID or document checks to minimize fraud and improve throughput.
  • Risk Flagging: Pre-screen phone numbers to detect high-risk users before approving risky accounts or actions.
  • Profile Enrichment: Capture demographic data tied to phone ownership for analytics or personalized experiences.
