South Carolina towns list more on the Register than most of the country (a typical South Carolina town has 3.2 per 10,000 residents, the U.S. 2.4), so Dillon’s 112 sits above most of its state (85% of South Carolina towns have fewer) while its 71 historic buildings outnumber those of 87% of U.S. towns.

Dillon County was founded in 1910 from a portion of Marion County. The county and the city of Dillon are named for prosperous local citizen James W. Dillon (1826−1913), an Irishman who settled there and led a campaign to bring the railroad into the community. The result of this effort was the construction of the Wilson Short Cut Railroad, which later became part of the Atlantic Coast Line Railroad, and which brought greater prosperity to the area by directly linking Dillon County to the national network of railroads. For many decades, residents of Dillon County were primarily loggers and farmers growing cotton and tobacco. Timber harvesting remains a major industry in the county. Dillon County has seen growth in manufacturing and distribution centers over the past 20 years due in part to Interstate 95, which runs north-south through the county.
The Dillon post office opened in 1888, the earliest record of the town by name (U.S. post office records).
