TDS Risk

Self-serve mobile carrier signals API for UK businesses TDS Risk is a self-serve API that lets any UK business check a mobile number against live carrier data from EE, O2, Vodafone and Three. Normally, getting access means weeks of due diligence with each network. TDS Risk handles carrier approval centrally, so you can sign up, declare your legal basis and use case, add the privacy wording the platform generates for you, and make your first live check in under 10 minutes. Trust Score returns a 0 to 1000 score with SIM swap timing, line type, call forwarding, public number exposure and reason codes, so you can spot account takeover, SIM swap fraud and fake submissions before they reach your stack. Mobile KYC matches name, address and date of birth against the carrier record and flags lost or stolen handsets, helping catch synthetic identities and impersonation without documents. Every check produces a cryptographically signed, immutable audit record. Checks do not affect credit files. No contracts, no minimums, one price for every business. Freemium: 20 free checks on sign-up
