Neustar was founded in
Delaware in 1998 as a business unit within
Lockheed Martin Corporation. It was spun off to keep the neutrality that was essential to its original core contract with the nation's
telecommunications providers. In November 2006, it bought
Followap, Inc., a UK-based enabler of mobile
instant messaging services. In 2010, Lisa Hook was named the firm's president and
Chief Operating Officer. In January 2010,
The Washington Post reported that under Hook's leadership, Neustar was chosen by a consortium of Hollywood studios and technology executives to manage a system where consumers could access movies and other video entertainment from multiple digital devices. This system was named "UltraViolet". Over the next years, Neustar bought several companies including, TARGUSInfo (2011), Aggregate Knowledge (2013) and
.CO Internet (2014). Neustar entered into an
asset purchase agreement in 2015 with
Transaction Network Services for their caller authentication assets. The following year, Neustar planned to split into two independent publicly traded companies. This plan was abandoned later that year when
Golden Gate Capital and
GIC announced to buy all Neustar public shares for approximately $2.9 billion ($33.50 per share). This was completed by August 2017. Neustar lost its
Number Portability Administration Center (NPAC) contract in 2016 to
Ericsson subsidiary Telcordia. Neustar had administered the number portability system since 1997. The local-number-portability administrator (LNPA) was created to handle NPAC, which enables users to take their phone numbers with them when they switch service providers. The NPAC manages the routing of all calls and texts for more than 650 million US and Canadian phone numbers for more than 2,000 carriers. Charles Gottdiener was appointed as president and chief executive officer, succeeding Lisa Hook in July 2018. In October, Neustar announced that it bought
Verisign's security services customer contracts. This includes
DDoS protection,
DNS firewall, and managed and recursive DNS services customer contracts. Three months later, Neustar bought
TRUSTID, a caller authentication and fraud prevention systems provider for contact centers.
GoDaddy bought Neustar's domain name registry business in August 2020, which was then renamed
GoDaddy Registry. In late 2021,
TransUnion purchased Neustar's main business for 3.1 billion. However, Neustar's security business, Neustar Security Services, was excluded from the transaction and was sold separately to become a portfolio company of Golden Gate Capital and GIC, and was rebranded as Vercara in April 2023. On September 23, 2024, DigiCert acquired Vercara. ==Business==
