Please keep in mind that any comments or other information you post on our blogs may be read, collected, and used by other blog readers.

Neustar uses first-party and third-party Cookies to enhance your experience on our websites. When you first visit one of our websites with a new device or browser, we advise you about the use of Cookies on that site. You may choose to continue with Neustar website Cookies or turn them off. If you choose to continue with Cookies, we won't remind you for one year - but if you change your mind at any point please click here. Certain website features may not work properly if you elect to turn Cookies off. For example, some of our websites featuring shopping carts require Cookies to work properly.

Our websites may include social media features such as the Facebook "Like" button. These features, which are either hosted by a third party or directly on our site, may collect Internet Log Data and, in order to function properly, may set Cookies. Your interactions with these features are governed by the privacy policy of the company that provides them, and not this policy.

When you visit our website, we use PII that you provide, Pseudonymous IDs (e.g., from Cookies), and Log Data to respond to your requests, process transactions you initiate, improve our website, and deliver personalized content to you. We may disclose this information to third parties to help us in these activities, for example, to a service provider that sends email communications to you on our behalf.

Data Processed to Provide Neustar Products and Services

Neustar provides a variety of marketing, risk, communications, security, and registry solutions to help businesses and others make better decisions, better serve their customers, enable communications, and detect and respond to fraud, cybersecurity threats, and other malicious behavior. Customers may combine some or all features of our products and services described below.

Marketing Solutions

We provide a variety of services to online and offline advertisers and their agents through our marketing services offerings, including our Ad Advisor, Customer Analytics, Customer Experience and Customer Intelligence services.


Neustar Audiences, including AdAdvisor and our ElementOne segmentation solutions, enable advertisers to understand their CRM Data and to apply those insights to reach and communicate with their existing customers and large groups of similar households and individuals in the on and offline environments. To do this, we collect consumer survey data, reliably-sourced household/neighborhood-level demographic data, and other licensed lifestyle and purchasing data from third party providers, which we aggregate across US households and use to make predictions about the preferences and interests of large groups of similar consumers based on pre-defined market segments, identified by a numeric Segment Code (also called an “Element”). In addition, we enable our advertisers to reach and communicate with specific users who may be interested in their products and services based on pseudonymized Attribute Data derived from reputable sources.

We use this information to help advertisers deliver more relevant online content. We may share Pseudonymous IDs with our affiliates and service providers to support advertising customers. In order to enable our customers to use their information across the Internet advertising ecosystem, we "sync" Cookies with various ad platforms and tech providers. You can learn more about this process by reviewing our explanation of Cookie Sync Partners.

Customer Analytics

Neustar's MarketShare services compile and analyze aggregated sales data, aggregated online Event Data (which may include addressable and connected TV data), information about offline marketing activities, along with other economic modeling data and aggregate ad response data from a variety of platforms (on and offline) in order to measure ad campaign effectiveness and attribute conversion events to marketing campaigns. This enables advertisers to understand their customer's path to conversion and facilitate smarter marketing spend decisions. For customers using our Onboarding services, we may also collect Hashed eMail Addresses, Hashed MAIDs, and/or imprecise (city/metro area/provincial/state/zip level) Geolocation Data from data partners.

Customer Experience

Neustar's Customer Experience services connect data and media across channels (online, offline, television, etc.) to enable marketers to analyze the effectiveness of their advertising activities and determine where to invest in order to generate sales more efficiently.

  • IDMP. Neustar's Identity Data Management Platform (IDMP) collects, and aggregates Log Data, including Internet Log Data, Event Data, and other information that is generated when you visit the websites of our publisher, retailer, and advertiser customers or when their ads are delivered to you on a third-party website. We use Psuedonymous IDs such as DIIs, Cookies, Mobile Advertising IDs or MAIDs, Pixel Tags, Web Beacons, Statistical IDs, third-party identifiers and other Pseudonymous IDs that do not, by themselves, identify a specific individual. In addition, the IDMP offering enables customers to use their own or third-party Attribute Data to improve the accuracy and performance of our IDMP.

    We aggregate and normalize this information, along with website and pseudonymized CRM Data and, in some cases, pseudonymized Attribute Data in order to provide insights about the demographics and interests of an advertiser's customers and prospects, the advertisements they see, and how they interact with online content. Customers may also receive pseudonymized Cookie-level data using Neustar's Data Science Development Kit (DSDK) to perform their own analysis and aggregation. Customers use our aggregation reports and/or DSDK to improve the performance of their advertising campaigns, to better understand their audiences, and to enhance the relevance of advertisements.

    Neustar collects Event Data to help our customers analyze and understand how effective their advertising is. Our customers may use our services to understand how you interact with them across their own and partner/third party web properties, and to communicate with you more effectively based on that information. In some cases, these advertisers use Neustar tools to build consumer profiles (e.g., "gardener" or "sports enthusiast") or predict consumer preferences based on a specific person's online behavior over time and across related and unrelated websites. Our customers use this information to communicate with consumers who are likely to be interested in their products and services.
  • Data Onboarding. Using a process called Cross Device Linking, we create and store linkages between and among household or individual level Pseudonymous IDs such as DIIs, Cookies, Mobile Advertising IDs or MAIDs, Pixel Tags, Web Beacons, Statistical IDs, and other third-party identifiers, including connected and addressable TV Identifiers, that do not, by themselves, identify a specific individual. We use these linkages to "onboard" or associate customer-provided segmentation information with third party DII. We use this information on behalf of our customers to measure and analyze the effectiveness of particular advertising campaigns and understand at an aggregate level the impact these campaigns have on off and online behavior. Our customers or their agents may also use this information to target advertising based on consumer preferences and characteristics, including pseudonymized Attribute Data.
  • Remarketing. We also use Pseudonymous IDs along with Event Data, Attribute Data, the stored cross-device linkages discussed above, and in some cases, customer CRM Data to help our customers re-market to their web site visitors. For example, we may generate a list of households associated with visitors to an advertiser's website and provide that list to a neutral third party for follow up postal mail or email. Unless a user has expressly consented, we segregate DII from PII, such as address, and take other steps to ensure that this information is not merged.
  • Website Personalization (PageAdvisor). Neustar collects Pseudonymous IDs and passes on the associated Segment Codes and Attribute Data so that our customers can customize content, advertisements, or offers displayed to their website visitors in real time.
Customer Intelligence

Neustar's Customer Intelligence service uses PII collected from a wide variety of public and private sources. Our business customers use this information to identify or verify the identity of existing customers and prospective customers who contact them (for example through their customer service center, online forms, or lead generation channels) to provide better customer service, communicate more effectively, use their marketing resources more efficiently, and comply with various laws and regulations. Customers also use these services to correct, update, and enhance their CRM Data and, in combination with our predictive market segmentation tools described below, to offer products and services you may be interested in.

Risk Solutions
Compliance Intelligence

Neustar's TCPA Compliance service helps customers mitigate regulatory risk and improve operational efficiencies by verifying the linkages between a consumer's name, phone number, valid consent, and other offline attributes. This helps our customers comply with the Telephone Consumer Protection Act by confirming that the number they are calling belongs to the consumer who provided consent to be contacted at that number.

Fraud Intelligence

Neustar uses data from a variety of sources, including offline data, customer provided data including PII, third-party licensed data, and Cross Device Linking data, or other digital identifiers (e.g., IP Addresses, and Cookies, Mobile Advertising IDs or MAIDs, and Statistical Identifiers to help our customers verify their registered customers, prevent, detect, investigate and respond to fraud and other malicious behavior, and to achieve operational efficiency.

Neustar helps our customers achieve inbound and outbound operational efficiency and prevent fraud by matching, enhancing, correcting, or corroborating their CRM Data. Neustar provides phone attribute information (e.g., whether the phone has been ported, disconnected, or changed recently) to help our customers defend against potential fraud, account takeover, and spoofing. Information from Cross-Device Linking can also be used in connection with our IP Information and IP Reputation services to flag potentially fraudulent account opening activities.

Neustar’s TRUSTID Authenticator and Indicator Software as a Service products service provides an ownership-based authentication token that allows call centers to identify trusted callers before their calls are answered. Call center customers transmit data associated with inbound calls to Neustar, which Neustar uses on behalf of the customer to determine, among other things, whether or not a calling party number has a high probability of being intentionally falsified. This enables businesses to identify and protect again potential identity theft.

Operational Intelligence

Neustar uses a combination of internal and external sources to provide our Right Party Contact/Call Window service. The service is built using offline date and time information about access to proprietary Neustar data repositories that support a variety of our products, overlaid with offline insights about phone type and activation date. All of these inputs are aggregated across time and analyzed using complex rules to predict day/time windows when you are most likely to be available to answer your phone. Our customers use these insights to comply with the Telephone Consumer Protection Act and consumer protection rules regarding outbound calling, identify and mitigate fraud, and enhance the efficiency of their outbound calling programs.

Security Solutions
Application Security SiteProtect
DDoS Security

Neustar SiteProtect and Web Application Firewall services collect and process network traffic information containing both source and destination IP Addresses, Referrer URL, and other Internet Log Data to help our customers identify and respond to cyber-attacks and other malicious online traffic, including distributed denial of service (DDoS) attacks. Neustar will analyze the attack vector information containing the source and destination IP Addresses, attack duration, and traffic volume to enhance Neustar's ability to detect and mitigate malicious activity on the Internet more broadly. Based on this analysis, Neustar may share information about malicious activities, blocked hostnames or IP Addresses, source and target geolocation data, and target industry or vertical information with third parties such as internet security research groups and service providers to prevent, detect, and mitigate against malicious online behavior.

DNS Services

Neustar provides a variety of Domain Name System (DNS) services, including both authoritative and recursive DNS servers and a suite of related services to facilitate the global flow of Internet traffic. In providing these services, Neustar collects and processes DNS queries, which includes both source and destination IP Address information, time and date stamps, and other technical information. We use this information to provide connectivity and routing services to our customers, to investigate, identify and mitigate malicious and fraudulent activity, and to enhance our Digital Defense, Digital Performance, and Fraud, Risk, and Compliance products and services.

Security Intelligence
IP Geopoint Intelligence

We collect IP Addresses and other geolocation-related information using proprietary, patented technologies to map routable IP Addresses worldwide. By augmenting our data with insights derived from select global partners, we provide city-level data down to postal codes. We may use Geolocation Data from reputable sources to enhance our Risk Solutions services. Our IP Intelligence services also use IP Address and other Geolocation Data information to help our customers detect potentially fraudulent transactions (i.e., by flagging suspicious IP Addresses or log-ins from unlikely locations), and comply with geographic sales and content delivery regulations.

IP Reputation

Building on Neustar's suite of Digital Defense Services, we collect IP Addresses and analyze trends and patterns associated with them. By augmenting our data with insights derived from select global partners, we provide risk scores that allow our customers to determine whether an IP Address is a real human user (vs. a bot) or whether malicious activities have been associated with the IP Address in the past. Our customers may use this information to detect, prevent, and respond to fraud and other risks.

Website Performance Management

Neustar collects Internet Log Data and geolocation data along with website performance metrics such as, total load time, page rendering time, and any JavaScript errors to provide a variety of Web Performance Tools that enable our customers to monitor their site's performance and load time, to identify and address technical problems quickly, and to understand and improve their users' online experience.

Registry Solutions

When you register a domain name, your registrar collects certain information, including your PII, the IP Address of the servers on which your domain name is hosted, and other information about the registrant and the domain name registration. As the Registry Operator for .BIZ and .US, and as the registry service provider for other top-level domains, Neustar collects this information from registrars. We use this data to provide registry services, to enforce our policies and our customers' policies, and to prevent, detect, and respond to malicious behavior and/or misuse of our services. We also make this information available online, in accordance with applicable law and/or policy or contractual requirements imposed by the Internet Corporation for Assigned Names and Numbers (ICANN) and/or our registry customers. For example, WHOIS information for .US is publicly available in accordance with United States government policy. Neustar makes PII contained in the WHOIS database for the .biz domain available upon request to third parties with a legitimate and proportionate interest in using the data for non-marketing purposes such as consumer protection, crime detection, intellectual property protection, etc. Availability of WHOIS data for other domains that we support (either country-code or generic top-level domains) is determined by our customers in accordance with their regulatory and/or contractual requirements.

Neustar uses WHOIS Data and other information collected in the course of providing registry services to: comply with contractual requirements, ICANN policy requirements, law and regulation; 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, fraudulent or deceptive practices, counterfeiting or other activity that is contrary to applicable law. Neustar may from time to time collect and aggregate demographic data or statistical analysis and other research but does not disclose PII in that process.

Neustar prohibits use of WHOIS Data (1) except in compliance with applicable law; (2) to allow, enable, or otherwise support the transmission of mass unsolicited, commercial advertising or solicitations via direct mail, electronic mail, or by telephone; (3) in contravention of any applicable data and privacy protection laws; or (4) to enable high volume, automated, electronic processes that interact with domain name registry systems.

Communications Solutions

Neustar provides a variety of services to communications services providers to ensure that calls are properly routed across telecommunications service provider networks. These services include Caller ID/Caller Name (CNAM) services and optimization, branded contact management, robocall detection and mitigation services, domestic and international number resolutions services, directory listings management, business listings, numbering and order management services, and other services provided to communications services providers and other businesses. Our use and disclosure of this information is limited by contract.


Neustar maintains and operates the global phone number resolution directory service, Pathfinder on behalf of the GSMA for SMS routing and delivery. Customers of Pathfinder are restricted to use this service only for the purposes of rating, routing, and routing administration. For this service Neustar collects the phone number (queried by our customer), IP Address of the customer submitting the query and our response to the customer's query. Neustar's Pathfinder response consists of the carrier of record for the queried phone number and any number port history information.

Order Management

We provide services to help communications companies manage their domestic US phone numbering inventory, manage and fulfill customer number porting orders, and to comply with regulatory requirements. For these services we collect telephone numbers, IP Addresses, and carrier information. Our use and disclosure of this information is limited by contract and regulated by law.

Directory Listing and Caller Name

In addition to providing traditional directory services, Neustar helps our customers reach their customers and prospects with branded caller identification and business listing services.


Neustar maintains business listing information for our small business and franchise customers so they can be found by their customers and prospects. For Neustar's Localeze service, we collect business name, address, phone, email, website and service type information and publish this information through various media channels.

Neustar Services Cookies

We use Cookies, Web Beacons, Pixel Tags, Mobile Advertising IDs, Statistical IDs, and similar technologies in order to collect the information necessary to provide Neustar services described above. Our Cookies contain Pseudonymous IDs and other information that does not allow you to be identified without additional data. The contents of our Cookies are encrypted and can't be read without the encryption key. You can remove persistent Cookies by following directions provided in your Internet browser's "help" file, or you may opt-out as described below.

Our Pseudonymous IDs, including Cookies do not tell our business customers who you are or where you live. Businesses use the information in Cookies to tailor online advertising based on the likelihood that someone will share certain interests or propensities with members of an aggregated group. We also use and disclose information about Cookies, in combination with Log Data and third-party information, including Attribute Data, to measure the effectiveness of ad campaigns. Finally, our Cookies can be used to help a business verify a user when they access the site using a different device or browser and for other fraud prevention, detection, and mitigation purposes.

Mobile Advertising IDs

We use Mobile Advertising IDs or MAIDs, also known as "IDFA" (Apple/iOS) or "IFA" (Google/Android), in connection with Neustar's Marketing Solutions and Fraud, Risk & Compliance Solutions offerings. We obtain Mobile Advertising IDs or MAIDs from Match Partners who have user consent to share this information. We share Segment Codes associated with Mobile Advertising IDs or MAIDs with our customers who have access to these identifiers with the consent of their users. This enables our clients to provide a more tailored user experience as well as relevant content and offers in the mobile environment. We also use Mobile Advertising IDs or MAIDs to identify and prevent fraudulent transactions and to help our customer verify a known user who accesses their site using an unknown device or browser. You can find more information about how Mobile Advertising IDs or MAIDs are used and how to opt out of mobile advertising in our Transparency and Choice; Opt-Out & Access section below.

Web Beacons

We may use Web Beacons to collect performance metrics when you visit our customer's web sites. The web beacons capture your IP Address to determine your geolocation at the city/region/country level and is discarded once geolocation is determined. Understanding the geolocation and associated website performance helps our customers manage their websites for optimal performance.

Sensitive Data

Neustar does not create Segment Codes or other audiences based on Sensitive Personal Information, although some of our customers may do so consistent with applicable law. Neustar does not use Cookies, Mobile Advertising IDs or MAIDs, Statistical IDs, or other technologies to enable ad targeting based on that kind of information. For added protection, our contracts with our partners do not allow the use of our data to determine credit worthiness or eligibility for insurance, employment, housing, etc.

We do not create audience segments based on the precise real-time Geolocation Data without opt-in consent.

General Health Related Audiences

Neustar creates certain audience segments based on our predictions about the likelihood that households assigned to a particular Segment Code or audience are more or less likely to use certain kinds of over-the-counter medications (e.g., cold or flu medications) or more or less likely to consume certain alcoholic beverages. These segments do not include or reflect individual or even household level behavior; rather, they are predictions based on survey responses from volunteer participants, which is then modeled to apply to broader groups of people who we think are more or less likely to have similar preferences. Advertisers who use these segments must comply with government regulation as well as industry best practices that apply to the delivery of such advertising. More information about this topic and a list of the audiences we offer is available here: Health, Alcohol, & Political Advertising.

Political Audiences

Neustar creates certain audience segments based on our predictions about the likelihood that households assigned to a particular Segment Code or audience are more or less likely to vote, registered to vote or more or less likely to have a certain particular political outlook. These segments do not include or reflect individual or even household level behavior and they are not derived from voter registration lists; rather, they are predictions based on information received from opt-in survey respondents from volunteer participants, which is then modeled to apply to broader groups of people who we think are more or less likely to have similar preferences. Advertisers who use these segments must comply with government regulation as well as industry best practices that apply to the delivery of such advertising. More information about this topic and a list of the audiences we offer is available here: Health, Alcohol, & Political Advertising.

Credit Card Information

Neustar may collect credit card information when provided by our customers in payment for some of our services. This information is securely collected and transmitted by our vendor in accordance with Payment Card Industry standards and used and disclosed only for the purposes of receiving payment for our services.

Data Retention

Neustar Website Cookies

We retain information collected through our websites for as long as your account is active or as needed to provide you services. We also retain and use this information as necessary to comply with our legal obligations, resolve disputes, and enforce our agreements.

Neustar Services Cookies

  • We retain raw, cookie level data associated with our services for up to 19 months. At the time of collection, we also create aggregated data that cannot be re-associated with an individual cookie. We may retain this aggregated data for a longer period as required by law or otherwise necessary to resolve a dispute and enforce our agreements.
  • Neustar service Cookies expire in twelve months, although additional user registration at an on-boarding partner site may result in the placement of a new Cookie.
  • Associations made through Mobile Advertising IDs or MAIDs expire 12 months after the last time you interact with a partner website or advertiser.
  • For Cookies originating on websites in the European Economic Area (EEA), we collect and promptly hash full IP Addresses into a 64-bit integer. We also collect a truncated IP Address (dropping the last octet). The truncated and hashed IP Addresses are then forwarded to the U.S. using a secure transmission protocol. Full IP Addresses are captured by the application log file but are used exclusively for operations and deleted after 10 days.
  • Upon request we will provide you with information about whether we are processing PII about you. Please visit the Privacy Choices page on our web site.
    • If you are a resident of the EEA, you will be directed to a portal from which you may exercise your rights as a data subject under the General Data Protection Regulation (GDPR) including a confirmation of processing, access, objection, correction, and erasure. Additional information about Neustar's compliance with GDPR is available here: GDPR: What You Need to Know. We process all such requests promptly in accordance with the requirements of the GDPR.
    • If you are not a resident of the EEA, you will be directed to a portal from which you may access, correct, or block use of your personal information for most purposes. We will respond to your request within a reasonable timeframe.

We comply with opt-out requests by placing an "opt-out cookie" on your computer or device. Consequently, if you clear your Cookies on that computer or device, we will not be able to read our "opt-out cookie" and may resume collecting information from that computer or device for purposes of retargeting. Similarly, an opt-out request will not be effective on other browsers, computers, or devices you may use if you have not opted out while using that browser, computer, or device.

Please note Cookies are browser and device specific, so you must opt out on all of the browsers (e.g. Chrome, Safari) and devices (e.g. laptop, smartphones) you use.

Mobile Advertising IDs or MAIDs

  • You can opt-out of our use of Mobile Advertising IDs or MAIDs set by Android devices via the Neustar Choice Portal link in the Privacy Choices page on our website. Because Apple does not disclose their IDFA to users, we are not able to establish a block based on an Apple MAID (IDFA) in our system.
  • In addition:
    • Apple's iOS IDFA can be reset by the user at any time. Users can opt out of all remarketing by enabling a device setting called "Limit Ad Tracking" (LAT), which restricts advertisers from using the IDFA for behavioral advertising. You can learn how to limit ad tracking on your iOS device or to reset your IDFA here: IDFA Opt-Out.
    • Similar to IDFA for Apple devices, Android devices pass the Google Advertising ID, which provides the same type of device-specific, unique, resettable ID for advertising as Apple IDFA or IFA. You can learn more about how identifiers on mobile devices are used for advertising and receive instruction for how to opt out of mobile advertising on the Google Privacy & Terms webpage.
    Please note MAIDs are device specific, so you must opt out each mobile device (e.g. smart phone, tablet) that you use.

Hashed eMail Addresses

We work with a variety of Match Partners and Coverage Partners who may provide Hashed eMail Addresses for use in connection with several of our services. You can opt-out of our use of your Hashed Email Addresses in connection with Neustar services by clicking on the Neustar Choice Portal link in the Privacy Choices page on our website. We will retain your email address on an internal "block" list to prevent its further use in connection with Neustar services.

If you use several email addresses you must opt out for each one.

You can also choose to request deletion or access to certain personal information that Neustar may have about you. Please visit our Privacy Choices page to better understand your privacy choices. Please note that opting out of Neustar's processing of your data does not mean you will block online advertising altogether or see fewer ads. It simply means that the ads that you see will not be personalized for you. Ads may be served because they relate to the website you are visiting or to your current search, or they may just be randomly placed.

Your choice to use any of our opt-out tools will not affect ads placed by any other organization.
