Area code 704 serves the Charlotte metropolitan area in North Carolina, along with surrounding counties. It is one of the original codes created in 1947 and initially covered the entire state. Due to rapid urban growth, particularly in Charlotte, it was split and later overlaid with area code 980. Charlotte is a major banking and financial hub, home to Fortune 500 companies, and a key player in the southeastern U.S. economy. The 704 area code is deeply linked with Charlotte’s identity and often appears in local branding, sports, and business communications. Ten-digit dialing is required due to the overlay system.
