What is the area code for Columbia?
573 is the primary area code that serves Columbia, Missouri. This code covers a broad swath of central Missouri, including the city of Columbia and its surrounding communities, and has been in use since the mid-1990s as part of the North American Numbering Plan reallocation. This number is the standard local dialing prefix for both landlines and mobile lines within the Columbia metro area.
Background and context
Columbia sits in Boone County and has experienced steady population growth since the late 20th century; as a result, the 573 area code region has needed to accommodate rising demand for phone numbers while maintaining efficient routing for callers in central Missouri.
