What is a county seat?

By the CountyFinder editorial deskData as of November 1, 20264 primary sources

"County seat" shows up on forms, in jury summons and on every county page on this site. It is a simple idea with more exceptions than most people expect: counties with two seats, counties with none, and seats that sit outside their own county. This guide explains what a county seat is, counts the exceptions from Census and Wikidata files, and shows how to find yours.

What a county seat is

A county seat is the city or town that serves as the administrative center of a county. It is where the county courthouse stands and where the county's governing body (a commissioners court in Texas, a board of supervisors or commissioners elsewhere) usually meets. County offices such as the clerk, the tax assessor and the sheriff typically have their main office there, although large counties also run branch offices.

The name varies with the county type: Louisiana has parish seats and Alaska has borough seats. The idea is the same. In everyday life the county seat is where you go to file a deed, get a marriage license, appear for jury duty or attend a county court hearing.

How many counties have one, two or no seat

Matching Wikidata's "capital" property to the Census Bureau's list of 3,144 counties and county equivalents, and removing seats Wikidata marks as former, gives this picture ^[1][2]:

So nearly every county has exactly one seat. The two small groups, counties with two seats and areas with none, are explained below.

Counties with two county seats

Wikidata lists two current seats for 28 counties, most of them in Arkansas (10) and Mississippi (10) ^[1]. If you need a county office in one of these counties, check the county's own website for which town handles it before you travel.

Counties with no county seat

89 county-level areas have no seat in our data ^[1][2]. Most of them are areas that are not counties in the governmental sense:

• 40 independent cities (38 in Virginia, plus Baltimore city (Maryland) and St. Louis city (Missouri)). An independent city is not part of any county; its city hall plays the role a county seat would ^[2].
• 11 Alaska census areas. The Census Bureau draws them in the part of Alaska that is not organized into boroughs, so that it can publish county-level statistics; there is no county government to have a seat ^[2].
• 9 Connecticut planning regions, the state's county equivalents in Census files since the 2020s change ^[4]. Read county FIPS codes for that switch.
• Carson City, Nevada and District of Columbia, each a single county-level area with one consolidated government ^[2].

That leaves 27 other areas for which Wikidata lists no current seat ^[1]. Where such a county has a seat, our source does not record it, so our pages say "not published" instead of guessing. The county's own website has the answer.

Is the county seat the biggest city?

Usually, but not always. For the 2,954 counties with one seat that we could match to a Census place in the same county, the seat is also the place with the most residents in that county in 2,134 cases, about 72% ^[1][3]. In the rest, a suburb or a newer city has grown past the old seat. The most populous counties where that happened:

Residents are those living in the county part of each place, from ACS 2019-2023 estimates ^[3]. Counties whose largest place is a census-designated place (a community without a city government) are left out of this table.

County seats in Texas

Texas has 254 counties. Wikidata lists one current seat for 251 of them ^[1]; for Bexar County, Hardeman County and Wood County it lists none, so those pages say "not published" until the source is fixed. In 57 Texas counties the seat is not the largest city or town ^[1][3], for example:

• Collin County: seat McKinney, largest Plano (281,736 residents in the county)
• Hidalgo County: seat Edinburg, largest McAllen (143,789 residents in the county)
• Fort Bend County: seat Richmond, largest Sugar Land (109,735 residents in the county)
• Williamson County: seat Georgetown, largest Round Rock (121,984 residents in the county)
• Brazoria County: seat Angleton, largest Pearland (112,141 residents in the county)
• Bell County: seat Belton, largest Killeen (156,144 residents in the county)

Every Texas county page lists its seat, and the Texas FIPS list has all seats on one page.

When the seat is outside the county

In Virginia, a county seat can sit in a city that is not part of the county at all. Virginia's independent cities are separate from the counties around them ^[2], yet 12 counties have their seat in one: Albemarle County (seat Charlottesville); Alleghany County (seat Covington); Augusta County (seat Staunton); Fairfax County (seat Fairfax); Frederick County (seat Winchester); Greensville County (seat Emporia); Henry County (seat Martinsville); James City County (seat Williamsburg); Prince William County (seat Manassas); Roanoke County (seat Salem); Rockbridge County (seat Lexington); Rockingham County (seat Harrisonburg) ^[1]. For example, Fairfax County's seat is the City of Fairfax, which is not part of Fairfax County.

The most common county seat names

Because so many counties and towns were named after the same people, seat names repeat a lot. The most common ^[1]:

• Jackson: seat of 11 counties
• Greenville: seat of 10 counties
• Marion: seat of 10 counties
• Monticello: seat of 10 counties
• Franklin: seat of 10 counties

That is one reason a town name alone is a poor way to identify a county; the FIPS code is unambiguous.

How to find your county seat

Find your county first: the county finder uses your location in your browser and shows the county with its seat, FIPS code and time zone; nothing is sent or stored. You can also type a ZIP code or a city. Every state page lists all its counties with their seats.

Honest limits

Our seats come from Wikidata, a CC0 database anyone can edit ^[1]. We drop seats that Wikidata marks as ended and re-check every county with two seats, but a recent change or a missing entry can still slip through, and Wikidata does not say which offices sit in which seat. Matching a seat to a Census place uses the name, so a seat with a different official name (for example a consolidated city-county) can go unmatched; those counties are left out of the percentage. For anything official, the county's own website is the authority.
