Using the Substitute Address

According to §24-30-2108(2), C.R.S., a participant's substitute address is their legal address for home, work, and school. ACP participants can choose where they share and use their substitute address; however, it is recommended that the substitute address is used wherever possible. When a participant decides to utilize their substitute address, it is the participant's responsibility to request use of the substitute address and provide confirmation of program participation.

Updating to the Substitute Address

ACP participants are responsible for ensuring that their substitute address is provided to any agency that may need an updated address, especially if that agency sends mail to the participant. The Participant Handbook, given to participants upon enrollment, provides guidance for navigating this transition. ACP staff can be contacted for any additional clarification.

Proper Address Formatting

Participants should have their mail addressed to their full substitute address, including the apartment number, as shown below. Mail that is addressed incorrectly may be delayed or returned to the sender.

Participant Name
1001 E 62nd Ave Apt       
Denver, CO 80216

Note: The ACP can only forward mail addressed to program participants. Mail addressed to a non-participant, a business name, or "in care of" a participant will not be forwarded (§24-30-2104(1)(b), C.R.S.).

Mail Delays and Returns

Participants should expect a delay of one or two business days. The ACP cannot forward packages, mail addressed to a business, trust, or similar entity, periodicals, or marketing mail. These items will be returned to the sender. Participants should refer to the Participant Handbook for more information on these policies.

Interacting With Government Agencies

It is the ACP participant's responsibility to notify government agencies about their ACP participation (§24-30-2108(1), C.R.S.). Participants must present their ACP authorization card when requesting use of the substitute address and agencies are authorized to make a copy of the authorization card (§24-30-2108(2), C.R.S.). Participants may also need to present other ACP-provided documentation. Participants should refer to the Participant Handbook for additional information and guidance for interacting with specific agencies.

Service of Process

The ACP is a 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 (§24-30-2104(3)(a), C.R.S.).

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