The other area codes laid over 864
Area code 864 does not have Greenville to itself. 1 other code — 821 — serves the same rate centres, laid over the same ground rather than dividing it. That is an overlay: a new code added when the old one ran out of numbers, covering the same streets. Two neighbours can hold different area codes, so the code says roughly when a number was issued rather than where it sits.
821350 blocks, 16 rate centres, mostly mobile
Each holds its own blocks and its own carrier mix, so a 864 number and a 821 number from the same street can report different line types. Filtering Greenville by area code needs all 2 of them.

Where 864 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Simpsonvl is shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 864 number still reports the carrier it started with. Closing that gap needs a live query against the routing database. How line type is derived.

Common questions
Where is area code 864?
Area code 864 covers Greenville, South Carolina. It is not the only code there: 821 is an overlay on the same rate centres, so a Greenville, South Carolina number can start with any of them.
Is a 864 number a mobile or a landline?
It can be either, and the digits do not say which. North American mobile and landline numbers share the same ranges, so the answer comes from the carrier holding the block. In 864 the split runs 45% mobile, 44% landline and 10% VoIP, so mobile is the most likely single answer.
Which carriers hold 864 numbers?
The largest holders are AT&T Wireless, Verizon Wireless, Onvoy. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 864 numbers are there?
The code holds 6,207 allocated blocks in our copy of the numbering plan. A block is 1,000 or 10,000 consecutive numbers depending on how deeply it has been pooled, so 864 covers on the order of 6,207,000 possible numbers — most of which have never been issued to anyone.
