Benton County White Pages Search
The Benton County White Pages gives you a single spot to look up people and pull public directory info from local record sites. Benton County sits in the southeast corner of Washington. It covers Kennewick, Richland, West Richland, and a good chunk of the Tri Cities. The county seat is in Prosser. Most county records are open to the public, which makes a resident search in Benton County easy if you know the right door to knock on. Use this page as a quick guide to the main white pages tools for the county.
Benton County Overview
Benton County White Pages Basics
People come to the Benton County White Pages for plain day to day needs. You may want to find an old friend in Kennewick. You may need a fresh address for a family member in Richland. Some folks want to match a name to a home in West Richland or Prosser. A white pages search pulls from voter rolls, parcel maps, and the free tools the county runs online. Put a name and a place together. That is the whole point.
Benton County does not run one master directory lookup. You piece it together from the offices below. Each one holds a slice of the full picture. A match in two sites turns a guess into a solid people search result.
Note: the Benton County White Pages uses only open public records, so sealed and redacted files stay out of view.
Benton County Homepage and Directory
The main Benton County homepage is the first stop for most people who start a resident search in the county. The site links to every department, elected office, and public records contact in one spot. From the menu you can jump to the assessor, the auditor, or the superior court. The homepage also has a staff directory you can search by name or office.
Here is a view of the Benton County homepage you see when you open the site.

Pick the office that fits your search. The site runs under the Washington Public Records Act, RCW 42.56, which keeps most county files open by default. If you cannot find a tool online, call the records clerk for help with a formal request.
Benton County Assessor Property Search
The Benton County Assessor runs the main property lookup for the county. You can search any parcel by owner name, street address, or parcel number. The result shows the current owner, the mailing address on file, the tax value, and past sale history. That makes the assessor the core tool for tying a name to a home in Kennewick, Richland, or any small town in the county.
Below is a view of the Benton County Assessor page.

The assessor site works best when you have a full name or a street. Type what you know, scan the list, and click the parcel for more. Past owners show on the parcel page, which helps trace a move back a few years. The office runs under RCW 84.40.
Benton County Auditor Records
The Benton County Auditor records real estate documents and runs elections. Deeds, mortgages, liens, and UCC filings all land at the auditor. The auditor also issues marriage licenses and keeps the voter roll. A name search at the auditor is a strong follow up to the assessor, since you can pull the full deed chain and any co owner names. Real estate filings fall under RCW 65.04.

Older paper records are on microfilm at the auditor's office in Prosser. Staff can pull files for you at the counter during normal hours. Plain copies are cheap. Certified copies cost more and carry the county seal.
Benton Superior Court Case Search
The Benton County Superior Court keeps civil, family, probate, and criminal case files. A case search by name can turn up lawsuits, name changes, and probate files. You can also search statewide through the Washington Courts public access site, which covers all 39 counties and is free. The state tool is often the fastest way to run a court name search on a Benton County resident.
Court records follow the rules under RCW 2.68 and General Rule 31. Sealed files and juvenile cases stay private.
State Tools for a Benton County Lookup
State level sites fill in the gaps the county sites leave. The Washington Voter Registration Database lets you confirm a person is a registered voter and the county of record. The roll runs under RCW 29A.08. The Washington State Digital Archives holds older records for the state and is a good spot to trace family ties to the Tri Cities.
Other useful tools: the Washington State Bar Association directory for a lawyer by name, the Washington Secretary of State corporations search for business filings, and the Washington Department of Corrections offender lookup. The Department of Revenue is a backup for business names.
Note: state sites are great for wide sweeps, but county offices still give the best current home address info for a Benton County resident.
Steps for a Benton County Resident Search
A simple plan makes a Benton County white pages search much faster. Start wide, then narrow. Two or three matches across sites give you a solid result.
- Start with a name search on the assessor site
- Pull the parcel and note the mailing address
- Check the auditor for recent deeds and liens
- Run a case search on the state courts site
- Confirm with the voter roll at the Secretary of State
If the name is common, narrow by city. A match in Kennewick will look different from one in Prosser or Benton City. Add a middle initial if you can.
Public Records Law in Benton County
All the offices above run under state law. The main rule is the Washington Public Records Act, RCW 42.56, which keeps most county files open by default. You do not need to give a reason to see a public file. You do not need to be a party to the case. Each office has its own request form and its own fee sheet.
Some items stay closed. Adoption files, juvenile records, and sealed court files are off limits. Social security and bank numbers are redacted from most files before they go online. If a judge sealed a record, it will not show up in a directory lookup at all.
Note: check the fee sheet before you file a formal records request, since per page costs can add up on a long file.
