Area code 864 serves the northwestern region of South Carolina, including cities such as Greenville, Spartanburg, Anderson, and Clemson. It was created in 1995 from a split of area code 803 to accommodate the Upstate’s growing population and economy. The area is a major industrial and technological hub, with strong ties to automotive manufacturing, particularly due to BMW’s presence in Greer. It is also home to several major universities, including Clemson University. The 864 code has become a symbol of South Carolina’s innovation and growth, particularly in business and education. It remains a standalone area code and a strong regional identifier.
