Neustar undergoes nine independent annual audits with respect to neutrality, privacy and security. All Neustar employees, board members and designated contractors are required to pass Quarterly Neutrality Certification.

Complaints must be submitted in writing and either hand delivered during normal business hours or mailed, by first-class mail, postage prepaid, to: Neutrality Officer Neustar, Inc. 46000 Center Oak Plaza Sterling, VA 20167.

The Neutrality Officer will answer any complaint in writing by providing a response within 30 calendar days from the time-stamped receipt of the complaint.

For more information on what the response will contain, refer to Section 300 of the Neustar Inc, Neutrality Requirements.

If Neustar is found to be in violation of the Neutrality agreement, the Neutrality Officer, in conjunction with the Neustar personnel involved in the alleged discrimination or favoritism and any other Neustar personnel that the Neutrality Officer designates, will develop an action plan to provide a remedy for the effects of such conduct, if any, and to prevent the recurrence of such conduct in the future. 

For more information on this topic, refer to Section 400 of the Neustar Inc., Neutrality Requirements.
