Counties are important units of government in Colorado since there are no townships or other minor civil divisions. Two of these counties, Broomfield and Denver, have consolidated city and county governments. Colorado's US state code is CO and its 2009 state code is 08. When the Colorado Territory first began creating counties in 1861, 17 counties (Summit, Larimer, Weld, Boulder, Gilpin, Clear Creek, Jefferson, Arapahoe, Douglas, Lake, Conejos, Costilla, Park, Fremont, El Paso, Pueblo, and Huerfano) and a Cheyenne Reserve were formed. In February 1866, the first new county, Las Animas, was created, followed by Saguache in December of that year. Bent County was created in February 1870, followed by Greenwood the following month. On February 2, 1874, Grand County and Elbert County were formed, and on February 10, La Plata, Hinsdale, and Rio Grande counties were created. Greenwood was absorbed into Bent on February 5. The last county to be created under the Colorado Territory name was San Juan County, created three months before statehood. By the time Colorado became a state on August 1, 1876, it had only 26 counties. In January 1877, Routt and Ouray were formed, followed by Gunnison and Custer counties in March. In February 1879, Chaffee County was created. From February 8–10, 1879, Lake county was renamed Carbonate County. In 1881, Dolores County and Pitkin County were created. In 1883, Montrose, Mesa, Garfield, Eagle, Delta, and San Miguel counties were formed, leaving the total number of counties at 39. The number rose to 40 in 1885 with the creation of Archuleta County on April 14. Washington County and Logan County were both created in 1887. Between February 19 and April 16 in 1889, Morgan, Yuma, Cheyenne, Otero, Rio Blanco, Phillips, Sedgwick, Kiowa, Kit Carson, Lincoln, Prowers, Baca, and Montezuma counties were formed, bringing the total to 55. By 1900, Mineral County and Teller County had been added. On November 15, 1902, Arapahoe County was split into Adams and South Arapahoe Counties, and Denver was consolidated as a city-county from portions of both newly-formed countie on December 1, 1902.[1] By 1912, Jackson County, Moffat County, and Crowley County had been created. Alamosa was created in 1913, and in 2001, Broomfield was recognized as a city-county, bringing the total to 64 counties. __TOC__ {{clear}}Counties{{Countytabletop| region_width = | fips_ref = [2][3] | region_seat_title = County seat | region_seat_width = | region_seat_ref = [4][5] | data2_title = Established | data2_width = | data2_ref = [6] | data3_title = Formed from | data3_width = | data3_ref = [6] | data4_title = Etymology | data4_width = | data4_ref = [6] | data4_unsortable = yes | population_ref = [7] | area_ref = [4] }}{{Countyrow|Name=Adams|N=08|Num=001|Seat=Brighton|Data2=1902-11-15|Data3=Split from Arapahoe County.|Data4=Named in honor of Alva Adams, the 5th, 10th, and 14th Governor of the State of Colorado.|Population=441603|Area=1182.29}}{{Countyrow|Name=Alamosa|N=08|Num=003|Seat=Alamosa|Data2=1913-03-08|Data3=Split from Costilla County and Conejos County.|Data4=Named for the cottonwood trees which grow along the Rio Grande and its tributaries.

The three-digit number is unique to each individual county within a state, but to be unique within the entire United States, it must be prefixed by the two-digit 2009 state code. This means that, for example, while Adams County, Colorado is 001, Belknap County, New Hampshire and Alachua County, Florida are also 001. To uniquely identify Adams County, Colorado, one must use the state code of 08 plus the county code of 001; therefore, the unique nationwide identifier for Adams County, Colorado is 08001.
