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.

How the Substitute Address Works

The substitute address is the address of the ACP office, plus an "apartment number" that is unique to each participant household. The apartment number allows ACP staff to sort participant mail quickly and efficiently. Since the substitute address is used for creating and updating public records, it is not confidential.

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.

Mail Handling Delay

Participants should expect a delay of one or two business days. Incorrectly addressed mail may be delayed further, or returned to the sender.

Package Policy

The ACP is unable to forward packages of any type, including mail-order medications. The only exceptions are license plates and packets of bank checks. All other items will be returned to the sender. ACP participants should make other arrangements to receive packages. The Participant Handbook includes suggestions on receiving packages while maintaining confidentiality.

Business Mail Policy

The ACP is unable to forward mail addressed to a business, trust, charitable organization, or similar entity. These entities are not eligible for program enrollment. The ACP will accept business mail only if the letter is addressed directly to the participant (not "in care of" or "to the attention of"). For more information, participants should refer to the Participant Handbook.

Service of Process and Legal Mail

The ACP acts as participants' legal agent for the purpose of accepting legal mail and subpoenas (or any other personally-served document) as long as the service is in the participant's legal name. When the ACP accepts service on behalf of a participant, the participant is legally responsible for complying with the requirements contained in the legal document(s). ACP staff will notify participants about the service and forward the served document(s) by mail.

Service of process will be accepted from 9 AM to 3 PM, Monday through Friday.

Enrollment Period

Participants are certified for four years at a time 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. The renewal process is initiated by ACP Staff, who will attempt contacting participants to confirm whether the household would like to renew certification.

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, including a unique "apartment number". Program participants may present their authorization card when creating or changing public records.

Emergency Release of Participant Address Information

The ACP is required to release a participant's actual address to a criminal justice agency if the information is required pursuant to a criminal justice trial, hearing, proceeding or investigation involving a participant. Requesting officials must meet the requirements set out in §24-30-2110, C.R.S. and 1 CCR 103-6, Rule 8.0, which includes a completed form, an agency letter, two officials, one notary and three signatures.
