Telesign

Telesign is a global platform for phone risk scoring (Telesign Intelligence), SIM-swap detection and protection against SMS fraud such as IRSF and artificially inflated traffic. It was founded in 2005 and is based in Los Angeles.

Products The listed products are Phone ID and Intelligence Score, SIM Swap Detection, Silent Verification, the SMS Verify API and a Number Deactivation Feed. The company says it filters out disposable rented numbers, such as those from SMS-Activate, at registration and checkout.

Customers and coverage Target segments are crypto, fintech, gaming, social platforms, e-commerce and PSPs. Coverage is stated as global, across 230+ countries and territories.

Pricing Telesign sells either on a pay-as-you-go basis or on an enterprise contract. Per-message and per-lookup rates are not published.

For payment companies, a phone score at sign-up is a cheap early signal that complements document checks, particularly where fake accounts are created in bulk with temporary numbers.
