Area code 864

About area code 864

NANPA lists 864 as an in-service geographic area code for South Carolina, first put into service on December 3, 1995. It is an overlay: 864 and 821 cover the same territory, so neighbors on the same street can have different area codes. It is in the Eastern time zone. The places with the most assigned exchanges include Greenville, Spartanburg, Anderson, Greenwood, and Seneca. By population, its largest named places are Greenville, Greer, Spartanburg, Anderson, and Simpsonville.

Who holds 864 exchanges

50 carriers hold the 784 central office codes assigned in 864. Bellsouth Telecomm INC d/b/a Southern Bell Tel & Tel has the most, with 172 (22%). 573 of the codes (73%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself. Numbers can move between carriers through porting, so a code's holder tells you where the block started, not where every number lives now.

NANPA assigns each central office code to a rate center, the local calling area that decides whether a call is local or toll. 864 has codes in 66 rate centers. The table lists the rate centers with the most codes, with the matching Census place where the abbreviation could be matched.

Optional AI agents (receptionist, sales, support or scheduler) can answer calls after hours or when nobody picks up, take messages, text, email and transfer to your team. They are billed from prepaid AI minutes at $0.25 per minute, identify themselves as AI, and may only place outbound calls to people who consented, between 8am and 9pm.
