Key cities include Columbia (the state's capital), Rock Hill, Sumter, Aiken, and Fort Mill.

Its establishment in 1947 and extensive coverage of numerous cities and counties underscore its importance in the state's communication network. The area code's location in the Eastern Time Zone is also a significant operational aspect.
