864 picked up a second code in August 2024, which leaves every business here with a small reprinting job. The larger question, in a manufacturing economy whose owners and customers are often five or six hours ahead, is which hours your phone is actually expected to work.

A recent overlay, and the job it left behind
864 was created in December 1995 for the Upstate. On 19 August 2024, 821 was laid over exactly the same ground. Not a split: no number changed, no part of the region moved, and 864 still reaches everything it reached before.
What did change is the dialling. Two codes sharing one map make seven digits ambiguous, so ten are now required for every local call. That is how numbering works rather than a provider setting, and nobody can switch it off for you.
Which means anything of yours still showing seven digits is incomplete: vehicle lettering, signage, invoice templates, printed forms, the website footer, a recorded greeting that reads the number out at the end, and any record a supplier or directory still holds. It does not fail for a caller who knows the code. It fails for the one who does not, and that is the caller you were advertising to.
A year on, the obvious places have mostly been caught and the ones left are the awkward kind. It is an afternoon of work with nothing to buy, which is exactly why it keeps getting postponed.
The time zone question nobody puts on a phone page
The Upstate has an unusual amount of advanced manufacturing owned from outside the country, and a supply chain built around it. For a lot of businesses here that means a parent company, a customer or an engineering counterpart who is five or six hours ahead, and it changes what the phone is for in a way no generic page covers.
The practical shape of it: their working day is ending as yours begins. A call that arrives at seven in the morning is not an early caller being keen, it is somebody at four in the afternoon trying to close something before they leave. If that call reaches a voicemail box, the answer does not come back until the next day, and a question that could have been settled in ninety seconds costs a day and a half.
So the thing worth setting up is narrow and specific: make sure calls landing in the first hours of your day reach a person rather than a recording. That might mean one named person covering an early window, or a rule that sends those calls to a mobile. It is a rota decision more than a software one, but the phone has to be told about it.
The same applies in reverse for anything your people need to ask overseas, which is why a system that lets somebody take a call from home at seven, on the business number rather than their own, earns its cost here faster than it does in a domestic-only business. Virtual phone system covers that part.
None of which makes the service local
There is no Upstate phone product. The software is the same one a business in Vermont is sold, it runs a long way from here, and the only thing your address decides is the three digits on the front.
How it works and what it asks of your connection are on the main business VoIP guide. The rest of the state, including the coast and the Midlands, is on business VoIP in South Carolina. Keeping digits you already have printed is on business phone numbers.
Who gains here
Beyond manufacturing and its supply chain, the working economy here runs on engineering and technical services, logistics along the corridor, healthcare, and a construction and trades sector that has been busy for a long time. Most of that is business to business with known contacts, and very little of it is walk-in trade.
For that shape the useful features are the plain ones and the list is short. A direct number per person, because the caller usually wants one particular engineer or account contact and knows their name. A greeting short enough to be a service rather than an obstacle. And a rule that moves an unanswered call to a named colleague before it reaches voicemail, because an overseas caller will not try twice. Auto attendant and extensions covers the front of that.
Who should not bother: one person, one phone, customers who already reach you fine. That is a monthly cost against a problem you do not have, and we would rather say it here than after you have signed. And if the connection into your building is unreliable, deal with that first, because voice is less forgiving than anything else you run over a line. VoIP vs landline is the honest case for copper.
Worth sorting while you are reprinting anyway
The overlay forces one job on every business here. These are the things worth deciding in the same sitting rather than separately a year later.

Common questions
Greenville VoIP questions
Did our 864 number change when 821 arrived?
No. 821 was overlaid on 864 rather than split out of it, so no existing number changed and none will. What changed is that every local call now takes all ten digits, and anything of yours printed with seven is incomplete. That is a reprinting job rather than a renumbering one, and it is worth walking the whole list rather than fixing the obvious places.
We get calls from Europe first thing. What actually helps?
Making sure the first hours of your day reach a person rather than a recording. That is mostly a rota decision, but the phone has to reflect it, whether that means one person covering an early window or those calls routing to a mobile. A caller whose own day is ending will not try again tomorrow if the first attempt reaches voicemail.
We were offered an 821 number. Will it look new?
Only to somebody paying close attention, and the number of those is smaller than you think. 821 covers exactly the same ground as 864 and has since 2024. If you already hold an 864 number it is worth porting rather than replacing, because it is printed on things you have paid for. If not, take what is available.
