Clarkston is the county&#8217;s largest city, with postal code 99403. The county has two incorporated cities, three census-designated places and two unincorporated communities, and runs on Pacific time.

Clarkston, on the Snake River across from Lewiston, Idaho, holds more than 90 percent of the county&#8217;s population; Asotin, a few miles upstream, is the smaller historic seat.<\/p>\n<div class=\"tv-table-scroll\">\n<table>\n<thead>\n<tr>\n<th>Place<\/th>\n<th>Type<\/th>\n<th>Pop.<\/th>\n<th>ZIP<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Clarkston<\/td>\n<td>City &middot; seat*<\/td>\n<td>7,161<\/td>\n<td>99403<\/td>\n<\/tr>\n<tr>\n<td>Asotin<\/td>\n<td>City<\/td>\n<td>1,204<\/td>\n<td>99402<\/td>\n<\/tr>\n<tr>\n<td>Clarkston Heights-Vineland<\/td>\n<td>CDP<\/td>\n<td>7,027<\/td>\n<td>99403<\/td>\n<\/tr>\n<tr>\n<td>West Clarkston-Highland<\/td>\n<td>CDP<\/td>\n<td>3,588<\/td>\n<td>99403<\/td>\n<\/tr>\n<tr>\n<td>Anatone<\/td>\n<td>CDP<\/td>\n<td>52<\/td>\n<td>99401<\/td>\n<\/tr>\n<tr>\n<td>Rogersburg<\/td>\n<td>Unincorp.<\/td>\n<td>&mdash;<\/td>\n<td>99402<\/td>\n<\/tr>\n<tr>\n<td>Silcott<\/td>\n<td>Unincorp.<\/td>\n<td>&mdash;<\/td>\n<td>99403<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>*Asotin, not Clarkston, is the legal county seat, though Clarkston is by far the larger city. Several names from older lists of the area &mdash; Cloverland, Craige, Grahams Landing, Grouse, Hanson Ferry, Jerry, Mountain View and Vineland &mdash; are historical place names, rural crossroads or superseded by the Clarkston Heights-Vineland and West Clarkston-Highland CDPs rather than standalone populated places, and are omitted here for lack of a current, verifiable population or postal listing.<\/p>\n<h2>ZIP Codes<\/h2>\n<ul>\n<li>99402 &mdash; Asotin (also serves Rogersburg)<\/li>\n<li>99403 &mdash; Clarkston (also serves Clarkston Heights-Vineland, West Clarkston-Highland and Silcott)<\/li>\n<li>99401 &mdash; Anatone<\/li>\n<\/ul>\n<p>These three ZIP codes cover the entire county; smaller communities use the postal town nearest them rather than a ZIP code of their own.<\/p>\n<h2>Geography<\/h2>\n<p>Asotin County sits in the Palouse region at the southeastern tip of Washington, where rolling wheat country in the north drops into the steep canyons of the Snake and Grande Ronde rivers along the Idaho and Oregon lines. The Snake River forms most of the county&#8217;s eastern boundary, and Hells Canyon country reaches into the county&#8217;s southern reaches. Garfield County lies to the north (<a href=\"https:\/\/townsvillages.com\/us\/garfield-county-washington\/\">Garfield County<\/a>), Nez Perce County, Idaho, lies across the Snake River to the east, and Wallowa County, Oregon, borders the county to the south.<\/p>\n<h2>Demographics<\/h2>\n<p>The 2020 census counted 22,285 residents, with Clarkston (7,161) and Asotin (1,204) the largest incorporated communities; most of the rest of the population lives in the unincorporated Clarkston Heights-Vineland and West Clarkston-Highland CDPs that ring Clarkston. Density works out to about 35 people per square mile. Median household income in the county runs somewhat below the Washington median of $94,605, reflecting the area&#8217;s farming and timber-based economy.<\/p>\n<h2>Economy &amp; Local Life<\/h2>\n<p>Agriculture, particularly wheat, and the timber and paper industry anchor the local economy. The Port of Clarkston, on the Snake River, handles grain barge traffic bound for Pacific ports and ships wood chips and sawdust to a Clearwater Paper mill in nearby Lewiston, Idaho. Recreation tied to Hells Canyon and the Snake River, including jet-boat tours and steelhead fishing, also draws visitors through the twin-city area of Clarkston and Lewiston.<\/p>\n<h2>History<\/h2>\n<p>Asotin County was created on October 27, 1883, carved out of Garfield County. Its name comes from a Nez Perce word generally translated as &#8220;Eel Creek,&#8221; referring to a stream near the town of Asotin. Clarkston was settled in 1862 and incorporated in 1902, taking its name from William Clark of the Lewis and Clark Expedition as a companion to Lewiston, Idaho, across the river, which honors Meriwether Lewis &mdash; though neither explorer is documented as having camped on the Clarkston side of the Snake.<\/p>\n<h2>Getting There<\/h2>\n<p>U.S. Route 12 runs through Clarkston and continues east into Idaho, while Washington State Route 129 climbs south out of Asotin toward Anatone and the Oregon line.<\/p>\n<ul>\n<li>Lewiston, Idaho &mdash; 1 mile east of Clarkston<\/li>\n<li>Pullman, Washington &mdash; 33 miles north<\/li>\n<li>Walla Walla, Washington &mdash; 100 miles west<\/li>\n<li>Spokane, Washington &mdash; 105 miles north<\/li>\n<\/ul>\n<p>Lewiston-Nez Perce County Airport, just across the Snake River in Idaho, is the nearest commercial airport, with regional service to Seattle and Denver.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<p><strong>Where is Asotin County, Washington?<\/strong><br \/>It occupies the far southeast corner of Washington, on the Snake River across from Lewiston, Idaho, and bordering Oregon to the south.<\/p>\n<p><strong>What is the population of Asotin County?<\/strong><br \/>22,285 people at the 2020 census.<\/p>\n<p><strong>How big is Asotin County?<\/strong><br \/>641 square miles (1,660 km2), of which 636 square miles are land.<\/p>\n<p><strong>What is the county seat of Asotin County?<\/strong><br \/>Asotin is the county seat, though Clarkston is the largest city.<\/p>\n<p><strong>How many towns and cities are in Asotin County?<\/strong><br \/>Two incorporated cities (Clarkston and Asotin), three census-designated places and two small unincorporated communities.<\/p>\n<p><strong>What ZIP codes are in Asotin County?<\/strong><br \/>99401 (Anatone), 99402 (Asotin) and 99403 (Clarkston).<\/p>\n<p><strong>Where does the name Asotin come from?<\/strong><br \/>It comes from a Nez Perce word meaning &#8220;Eel Creek.&#8221;<\/p>\n<p>More counties in this state: <a href=\"https:\/\/townsvillages.com\/us\/category\/washington\/\">Towns and villages in Washington<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Asotin County is a county in Washington, United States, in the far southeast corner of the state where the Snake and Grande Ronde rivers meet the Idaho border.
