Neustar (TransUnion)

Phone Intelligence and Identity Resolution at Scale

Neustar, now part of TransUnion following a $3.1 billion acquisition in 2021, is a leader in phone intelligence, identity resolution, and real-time risk data. Neustar's OneID platform links phone numbers to identity records, enabling organisations to validate caller identity, detect spoofed calls, and assess the risk of a phone number at the point of interaction. In the fraud context, Neustar's phone intelligence data is used to detect synthetic identities, identify stolen credentials, and flag suspicious account creation attempts. Its Trusted Call Solutions help financial institutions validate inbound callers before routing to agents — reducing call centre fraud and social engineering attacks. Backed by TransUnion's vast credit and identity data assets, Neustar now offers a more comprehensive identity intelligence layer than most pure-play phone intelligence vendors.
