864 is the area code for Greenville, South Carolina, in service since December 3, 1995, Eastern time. It is part of the 821/864 overlay complex — these codes share the same territory. Note that porting and VoIP mean a 864 number can be used from anywhere — the code marks where the number was assigned.
784 central-office prefixes are currently active in this code, spread across 50 code-holding carriers. Thousands-block pooling applies to 573 prefixes, so a single prefix can belong to several carriers. Its prefixes map to 66 distinct rate centers.
If a 864 call asks for money or personal data, treat the displayed number as unverified: hang up and reach the organization through its published number. Numbering data locates numbers, not callers.
Dialing: 10D locally, 10D to other codes (1+10 permissible dialing at service providers discretion).
NANPA projects numbering capacity for the 821/864 complex to exhaust in 3Q 2054.
864 was created from 803 in 1995. It has since spawned 821 (2024).

FAQ
Why am I getting spam calls from 864 numbers?
Scammers spoof recognizable area codes so calls look local or familiar. A displayed 864 number does not prove the call originated there — see our guide to spotting spoofed calls.
Where is a 864 number from?
864 is assigned to Greenville and surrounding areas of South Carolina in the Eastern time zone. The three digits after the area code (the prefix) narrow it down to a rate center.
Is 864 a toll-free number?
No. 864 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.
Why do 821 and 864 cover the same place?
They are overlays: when a code runs low on numbers, a new code is added over the same territory instead of splitting it. The 821/864 complex shares one service area, and local calls are dialed with 10 digits.
Will 864 run out of numbers?
NANPA's current forecast projects exhaust in 3Q 2054 — decades of capacity remain.
