Address Confidentiality Program (ACP)

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 an agent for services of process. In addition, we protect two usually public records - voting and marriage records.

• Is the ACP Appropriate for Me?
• Do I Qualify? 
• Application Process

All address confidentiality program participants receive the following:

• A substitute address to use with Washington state and local government agencies instead of their home, work or school address
• An ACP authorization card

Participants are certified for four years unless they withdraw from the program or are cancelled.

ACP depends on the advocacy training of advocates located throughout the state to help those wanting to enroll in the ACP. Interested people meet with an advocate who has been designated as an Application Assistant (AA) to create or review their safety plan and threat assessment before completing and application to apply for the program.

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 marketing 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
• Health Benefits Exchange Office

Where can I use the ACP substitute address?
