Address confidentiality program
In the United States an address confidentiality program allows survivors of domestic violence, sexual assault, stalking or other types of crime to be assigned a legal substitute address that is different from their actual residential address, in order to keep their location confidential. Program participants can receive mail at the substitute address and it will be forwarded for free, and are able to use the substitute address in government records.
