Neustar is a trusted, neutral provider of real-time information and analysis to the Internet, telecommunications, entertainment and marketing industries throughout the world. We apply our advanced, secure, data-driven technologies to our customers’ information to help them promote their businesses, serve their customers, and protect against fraud and cyber security threats.

Neustar is committed to the responsible use of personal information to help businesses make better decisions and deliver personalized content without sacrificing personal privacy. To accomplish this goal, we have adopted the principle of Privacy by Design, taking personal privacy into consideration throughout the process of designing, building, and delivering information products and services. This Privacy Policy describes our collection, use, and disclosure of Personal Information, which is information that personally identifies you, such as your name, email address or billing information, or other data that we can reasonably link to that kind of information.


Information You Provide on our Web Sites. On our web sites, we collect Personal Information only if you choose to give it to us, for example by subscribing to RSS feeds or blog posts or electing to “follow” Neustar on social media sites. Like all web sites, we automatically collect Log Data about your visits. This information does not identify you to us unless you have given us your name, contact information, or other Personal Information. We use Personal Information and Log Data to respond to your requests, process transactions you initiate, improve our web site, and deliver personalized content to you. We may disclose that information to third parties to help us in these activities, but we do not allow them to use the Personal Information for other purposes.

Domain Name Registry Services. When you register a domain name, your registrar will collect certain information, including your name, address, contact information, and the IP address of the servers on which your domain name is hosted. As the Registry Operator for .US, Neustar collects this information, known as “WHOIS Information” from registrars, and makes it available online in the WHOIS database.

Neustar uses WHOIS Information and other information collected in the course of providing registry services to: comply with law and regulation, and contractual obligations; investigate and respond to complaints of abusive conduct; and enforce registry policies related to, without limitation: WHOIS accuracy, the use of proxy and/or privacy registration services, limitations on registration, and prohibitions against the use of domain names to distribute malware, operate botnets, or engage in phishing, piracy, intellectual property infringement, fraud or deceptive practices, counterfeiting or other activity that is contrary to applicable law.

Neustar reserves the right to use and disclose this information as needed to provide the domain registry services, identify and respond to cybersecurity threats, protect our rights and the rights of third parties, and as required by law. In addition, Neustar may from time to time collect and aggregate demographic data or statistical analysis and other research, but does not disclose Personal Information in that process.

Other Use and Disclosure of Personal Information. Neustar does not use or disclose Personal Information other than as described above, except:

  • With your express permission;
  • Where permitted by our customer agreements, for internal use, research, fraud prevention, and product development;
  • To (i) comply with US or foreign laws or to respond to lawful requests and legal process in US or foreign civil, criminal or investigative matters, (ii) enforce agreements, our terms and conditions, and policies, and protect our rights and property as the site owner, and (iii) in an emergency to protect the personal safety of Neustar, its customers, or any person;
  • In an aggregated or de-identified form that does not directly identify you;
  • With third party vendors, consultants and other service providers who are working on our behalf, but we limit their access and use of Personal Information to that which is needed to carry out their work for us; and
  • In connection with any merger, sale of company assets, financing or acquisition of all or a portion of our business to another company.

Privacy by Design is an approach to protecting privacy developed by Ontario’s Information and Privacy Commissioner, Dr. Ann Cavoukian. Using this approach, privacy is embedded into the design specifications of technologies, business practices, and physical infrastructures. That means building in privacy up front – right into the design specifications and architecture of new systems and processes.
