Profile
Provides identity resolution, fraud detection, and communication routing services under TransUnion's B2B portfolio.
Neustar, originally founded in 1996 as a telecommunications numbering administrator, evolved into a provider of real-time information and analytics services before being acquired by TransUnion in 2021. The company's rebranding under TransUnion's B2B portfolio in 2026 marks its integration into a broader suite of solutions focused on marketing, fraud prevention, and communications. Neustar's legacy products, now branded as TransUnion TruAudience, TruValidate, and TruContact, continue to serve enterprises with identity resolution, cybersecurity, and call routing services.
Historically, Neustar reported $1.2 billion in revenue in 2016, with significant growth in marketing and security services. Today, its technology is used by over 4,300 companies globally, primarily in manufacturing and retail, according to Landbase data. The 2025 layoffs across the tech sector, including at Neustar's parent TransUnion, suggest ongoing restructuring as the company aligns with TransUnion's data-centric strategy. What's notable in 2026 is the quiet phase of Neustar's standalone brand, now operating as a white-label component of TransUnion's enterprise offerings.
