Address Confidentiality Program (ACP)

1 (800) 822-1065    (360) 753-2972    Fax: (360) 586-4388

The Washington Address Confidentiality Program (ACP) offers survivors of domestic violence, sexual assault, stalking, or trafficking, and Criminal Justice Affiliates, Election Officials, and Protected Health Care Workers who are a target for threats or harassment, a substitute mailing address to receive first class mail. The address is accepted by Washington state, county, and city government agencies in lieu of a residential address for creating records.

ACP is designed to help people who fear for their safety maintain a confidential address. Passed by legislature in 1991, ACP is used as part of an overall safety plan to prevent perpetrators from locating participants through public records such as driver licenses, voter registries and marriage records.

ACP provides services that work best as part of an overall safety plan. ACP provides a substitute address for eligible individuals and their household members. This address can be used on new records with government agencies and the courts. ACP also provides confidential mail forwarding services that includes acting as a legal agent for services of process. In addition, we protect two normally public records - voting and marriage.

New participants receive an authorization card with a substitute address to use when creating new public records with state and local government agencies. Participants are certified for four years unless they withdraw from the program or are cancelled.

ACP relies on the expertise of advocates located throughout the state to assist applicants. Applicants can meet with advocates who have been designated as an Application Assistant (AA) to apply for the program.

Pursuant to RCW 40.24.050, state and local agencies, law enforcement, and the courts shall use the ACP designated address as the participants address when creating a new public record. ACP participants must request the agency use of the designated address and may use it as their home, work, or school address. 

The secretary of state is designated as the legal agent for participants and accepts any summons, writ, notice, demand or process on behalf of the program participant (WAC 434-840-080).

To serve the secretary as an agent for the participant, include two copies and a check or money order for $25.00 made out to "Office of the Secretary of State". The outside envelope should be marked "Service of Process" to ensure proper tracking of receipt.

How does ACP help keep my information private?

All participant data is classified and maintained as private data by the ACP office. Measures are in place to secure participant data, which is extremely sensitive.

The ACP office will only disclose a participant's real residential address to a third party in response to a valid court order or law enforcement agency request. A formal request from a law enforcement agency is required to be signed by the agency's chief officer*.

*If a participant's abuser is a member of law enforcement then a law enforcement agency would be required to obtain a court order.

Does ACP forward all types of mail?

The ACP forwards all First-Class mail, including registered and certified mail. First-class mail includes all personal mail, bills, cards, letters, etc. The ACP will also forward bank checks. The ACP cannot forward packages, magazines, or junk mail.

Can ACP participants receive registered mail or subpoenas?

Yes. The ACP accepts personal and legal mail. The ACP can receive such mail on behalf of a participant and forward it to them. This is treated as a participant receiving the mail.

Does enrolling in the ACP keep participants safe?

ACP participation does not guarantee safety. If used correctly, the ACP can be a valuable addition to an overall safety plan. The ACP adds to, and does not substitute for, a comprehensive safety plan.

Must government agencies accept the substitute address on an ACP Authorization Card?

Yes, with very few exceptions. Washington state and local government agencies must accept the ACP substitute address when presented a valid ACP authorization card. They cannot require a participant to disclose their actual address.

Can ACP participants vote?

Yes. ACP participants receive ACP voter registration information and ACP specific voting forms when they enroll. ACP participants should not register to vote online or at any state government office. This includes:

  • Department of Licensing
  • Department of Social and Health Services

Where can I use the ACP substitute address?

ACP and Purchasing a Home

Buying a home or other real estate requires a person to sign many documents that list their name and the address or location of the property. These documents are available as public records. ACP laws do not currently provide protection for these types of property records.

Purchasing property records involves private businesses as well as state and local agencies. Private businesses like title companies, banks, real estate professionals, and mortgage companies, are not subject to Washington ACP laws. Private businesses may be willing to work with ACP participants even though they are not required to accept the ACP address.

ACP participants can use a specific type of Revocable Living Trust to purchase real property while using their ACP substitute address. ACP participants may want to check with an attorney before purchasing a home or other real estate to discuss options and any disadvantages.
