About the ACP

Address Confidentiality Program Services

The Address Confidentiality Program provides enrolled survivors of stalking, sexual assault and domestic violence with the following core services:

  • A legal substitute address
  • Mail forwarding

Participants use the substitute address for creating or changing public records. Participant mail is repackaged and forwarded to participants at their actual address. ACP services can enhance a comprehensive safety plan and contribute to increased survivor safety. These services are provided at no cost to the program participants.

Substitute Address

The ACP provides participants with a legal substitute address for home, school, and work. Generally, participants should use their substitute address instead of their actual address whenever possible. Under Colorado law, all state and local government agencies must accept a participant’s substitute address. Private companies may accept the substitute address, but are not required to do so.

Mail Forwarding

The ACP forwards all First Class participant mail on a daily basis. Mail is not forwarded on weekends and state holidays. The ACP forwards all First Class mail addressed to participants. First Class mail includes most types of personal mail, such as letters, postcards, and bills. This also includes certified and registered mail. The ACP cannot forward marketing mail (“junk mail” advertisements from businesses or nonprofits) or periodicals (magazines, newspapers, or newsletters). These items will be returned to the sender.

Enrollment Period

Participants are certified for four years, and may renew their certification for additional four year terms. Participants can continue program services as long as needed, and may voluntarily withdraw from the program at any time.

Program Materials

Once the ACP receives and processes a program application, the ACP sends the new participant household a “Welcome Packet” that contains program instructions, forms and authorization cards. The authorization cards reflect the assigned substitute address. Program participants must present their authorization card when creating or changing public records.
