Transparency and Choice; Privacy Choices


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

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. 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.


Neustar is a member of the Network Advertising Initiative ("NAI") and the Digital Advertising Alliance ("DAA") 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.
