In the United States an address confidentiality program allows victims of domestic violence, sexual assault, stalking or other types of crime to receive mail at a confidential address, while keeping their actual address undisclosed. In some states or jurisdictions, reproductive healthcare workers and employees of agencies that assist victims of domestic violence or stalking are also eligible.

Victims usually apply through a state's Secretary of State office. Once a victim is admitted to the program, they will receive a PO box or other address that will legally substitute their residential address on public records, such as voting registration.

According to the National Network to End Domestic Violence,

Address Confidentiality Programs (ACP) and Confidential Voter Listings are programs administered by the state enabling victims of domestic violence (and sometime victims of sexual assault and/or stalking) to participate in the voting process without fear of being found by their abusers. ACPs generally provide a substitute address for all public records. Confidential Voter Listings only provide confidentiality on election-related public records.
