There are 39 counties in the U.S. state of Washington. Washington came from the western part of Washington Territory. It was admitted to the Union as the 42nd state in 1889.[1] The first counties were created from unorganized territory in 1845.[2]
The Federal Information Processing Standard (FIPS) code, used by the United States government to uniquely identify counties, is provided with each entry. The FIPS code links in the table point to U. S. Census "quick facts" pages for each county.
