Interacting with a Program Participant

State and local government agencies are required to accept the designated address as a participant’s legal residential address after a participant presents their ID card.

Program participants are responsible for informing law enforcement that they are in the ACP. They must request that their designated address be used. A program participant cannot be required to disclose the confidential address to law enforcement. Officers can request to see the program participant’s ID card for verification.

The designated address should be used in any place where an address is asked or required, including but not limited to: Incident reports, citations, witness statements, arrest reports, etc. All forms of communication and correspondence should use the designated address. In instances where the actual location address must be recorded (e.g., officer daily logs), it is recommended that the entry be flagged as a confidential address under the ACP. Once flagged, it can be redacted in the event of a request under the Freedom of Information Act or subpoena.

A department of this state, a law enforcement agency, or a local unit of government may request the ACP to provide the confidential address of a program participant if the request is for a legitimate governmental purpose.  A request may only be submitted if the agency was unsuccessful in contacting the program participant using their designated address. 

To request the confidential address, complete the Confidential Address Disclosure Request Form.

The ACP will review all requests made through the website to determine what information should be released.  Requests can be made for the program participant’s enrollment status and confidential address.  However, requests made for the confidential address will be granted for legitimate governmental purpose only.

If the program participant is not identified in the request as a suspect in a criminal investigation, the program participant will receive notice of the request.
