N.C. Gen. Stat. § 15C-3

The General Assembly establishes the Address Confidentiality Program in the Office of the Attorney General to protect the confidentiality of the address of a relocated victim of domestic violence, sexual offense, stalking, or human trafficking to prevent the victim's assailants or potential assailants from finding the victim through public records. Under this Program, the Attorney General shall designate a substitute address for a program participant and act as the agent of the program participant for purposes of service of process and receiving and forwarding first-class mail or certified or registered mail. The Attorney General shall not be required to forward any mail other than first-class mail or certified or registered mail to the program participant. The Attorney General shall not be required to track or otherwise maintain records of any mail received on behalf of a program participant unless the mail is certified or registered mail.
