Cookies, Advertising IDs and Other Technologies

We may use Cookies, Mobile Advertising IDs or MAIDs, Statistical IDs, Web Beacons, Pixel Tags, JavaScript, HTML5 Local Storage, or similar technologies, along with other information described in our Privacy Statement to enhance and personalize your experience on our sites and to manage and enable preferences, transactions and related uses of Neustar services and information. These technologies do not identify you to us unless you have voluntarily identified yourself on our websites. If you've set your browser to warn you before accepting cookies, you will receive a warning message with each cookie. You can refuse cookies by turning them off in your browser, but some of the features on our site may not work if you do.

Transparency and Choice; Privacy Choices


  • You can opt out of the use of Cookies on Neustar websites by clicking here
  • You can opt out of Neustar services Cookies by clicking on the Neustar Choice Portal link in the Privacy Choices page on our website. This will allow you to click on an opt-out link to automatically opt out of the use of Cookies. In addition, Neustar’s Privacy Choices Portal also permits you to opt-out of the use of Hashed eMail Addresses and Android Mobile Advertising IDs as well as to learn about and exercise any rights you may have under applicable law.
  • You can also opt out of the use of Neustar services Cookies by using the Network Advertising Initiative (NAI) Consumer Opt-Out tool, the Digital Advertising Alliance (DAA) tool here, or the European Digital Advertising Alliance (EDAA) Opt-Out tool.
  • You can learn more about online advertising and privacy at the DAA's website

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.

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.

Online and Offline Data

You can choose to opt out of our use of Neustar’s Offline Data and Online Data for certain purposes. To do so, visit this our Privacy Choices page here. 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.


Self-Regulatory Bodies

Neustar is a member of the Network Advertising Initiative ("NAI"), the Digital Advertising Alliance ("DAA") and the European Interactive Digital Advertising Alliance (“EDAA”) and adheres to each organization's Codes and Principles. You can also learn more about online advertising in general on the NAI website, which provides background information on participating companies and permits you to opt-out of receiving tailored online advertising from some or all of its members.
