This is a list of the 64 counties of the U.S.
State of Colorado. The counties of Colorado
are important components of government
since the state has no secondary civil subdivi-
sions such as townships. Two counties, the
City and County of Denver and the City and
County of Broomfield, have consolidated city
and county governments.
Colorado’s postal abbreviation is CO and
its FIPS state code is 08.
