Why French fraud and KYC teams use carrier data

France's financial services sector, regulated by the ACPR and AMF, spans major banks, insurance groups, neobanks and a growing crypto market. French consumers are highly mobile and fintech adoption has accelerated. That growth brings onboarding fraud: synthetic identities, recycled numbers and VoIP lines used to create accounts at scale.

A carrier lookup at onboarding adds a fast, low-cost check that requires nothing from the customer. It distinguishes a genuine French mobile subscriber from a VoIP number bought for a few euros, identifies inactive numbers that suggest a recycled or abandoned line, and flags carrier mismatches where the serving network does not match the claimed location or customer profile.

SIM swap detection for French numbers: launching

SIM swap fraud is an active threat in France, targeting financial accounts that use SMS OTP for authentication. An attacker who gains control of a French mobile number can pass two-factor authentication and initiate fraudulent transactions before the victim reports the loss of service. Telebase is registering SIM swap feeds with French mobile operators and will return a recency signal when live. The field currently returns UNKNOWN. Early access is available for French-market teams who want to integrate ahead of general availability.
