TelcoSignal
TelcoSignal turns real-time telecom signals — SIM swap, number verification, device intelligence — into fraud prevention APIs. Built privacy-first, so your customers’ data is never exposed.
SIM Swap Detection
Flag SIM swap and porting events in real time before fraud completes.
Number Verification
Confirm number ownership and activity without ever seeing raw subscriber data.
Device Intelligence

Score Risk

Return Verdict
Only the risk verdict returns to the caller — never raw subscriber data.
