Greenville, SC Area Codes

Area codes serving Greenville

Greenville sits in South Carolina, part of the South region and the Eastern Time zone. Its numbers are spread across an overlay of 2 codes that all cover the same ground: 821, 864.

The original code is 864 (in service since 1995). As the area ran low on numbers, regulators added overlay codes on top instead of splitting the city, so longtime residents kept their numbers while new lines received a newer code.

How to pick an area code for a new number

When you activate a new line in Greenville, the carrier assigns whichever code has numbers available — you usually can't choose. If a specific code matters to you (for example the prestige of 864), ask the carrier whether any blocks remain, or request a number transfer. All codes here dial identically and cost the same.

Dialing in Greenville

Because Greenville is an overlay area, 10-digit dialing is mandatory: always dial the area code plus the seven-digit number, even for a neighbor. See 10-digit dialing and overlay area codes for the background. For every code in South Carolina, visit the South Carolina area codes page.
