Pindrop Phoneprinting Technology


Phoneprinting technology is highly resilient, verifying a legitimate customer or detecting the techniques fraudsters use to hide their true number. This technology identifies multiple callers associated with the same print, allowing enterprises to detect and track fraud rings.

Build Device Prints Call Center Phoneprinting

Phoneprint™ Signatures

Create unique prints of calling devices that can be used to identify repeat callers.

Why is the Technology Different?

Pindrop’s patented Phoneprinting technology uses the full audio of a call to determine its true characteristics. Call centers use this technology to detect anomalous behavior for first time callers and identify repeat fraudsters. It goes beyond ANI/CLI validation and provides universal coverage regardless of device type and call attempts.
