864 Area Code: Location, Time Zone, History, Scams, & Uses

Quick Facts About the 864 Area Code

The South Carolina Public Service Commission identifies Greenville, Spartanburg, and Anderson as the larger cities in the 864 region. Other covered areas include communities across Greenville, Spartanburg, Anderson, Pickens, Oconee, Greenwood, Laurens, Cherokee, Union, Abbeville, Saluda, McCormick, and Newberry counties.

South Carolina follows Eastern Time. Eastern Standard Time is UTC−5, while Eastern Daylight Time is UTC−4.

What Is the 864 Area Code?

The 864 area code is a geographic telephone code in the North American Numbering Plan. It primarily represents the Upstate region of northwestern South Carolina.

It is associated with residential customers, local companies, healthcare providers, schools, government offices, mobile users, and virtual phone systems. Having an 864 number generally indicates a connection with Greenville, Spartanburg, Anderson, or another Upstate community, although mobile and VoIP numbers can be used from almost anywhere.

Area code 864 now shares its geographic territory with area code 821. The overlay did not divide the region or change any existing 864 phone numbers.

Where Is Area Code 864 Located?

Area code 864 is located in the northern and northwestern portion of South Carolina, commonly called the Upstate.

Major cities and communities within the 864 area include:

• Greenville
• Spartanburg
• Anderson
• Clemson
• Greer
• Mauldin
• Gaffney
• Greenwood
• Easley
• Simpsonville
• Seneca
• Pickens
• Laurens
• Union
• Travelers Rest

The numbering region covers a mixture of growing cities, suburban communities, college towns, rural areas, and communities close to the Blue Ridge Mountains. NANPA describes Greenville, Spartanburg, and Anderson as the larger cities served by the 864 numbering area. Across the state line, western North Carolina uses the 828 area code.

What Time Zone Is the 864 Area Code In?

The 864 area code follows the Eastern Time Zone.

During standard time, the region observes:

• Eastern Standard Time
• EST
• UTC−5

During daylight saving time, it observes:

• Eastern Daylight Time
• EDT
• UTC−4

South Carolina observes daylight saving time, so clocks generally move forward in spring and return to standard time in fall.

Businesses calling customers in the 864 region should consider the local time. A call placed at 9:00 a.m. in Greenville is also 9:00 a.m. in cities such as New York, Atlanta, and Washington, D.C., when they are observing the same seasonal time.

Is 864 a Greenville Area Code?

Yes. 864 is one of the area codes used in Greenville, South Carolina.

Greenville is the largest and most widely recognized city associated with the 864 area code. However, 864 is not exclusive to Greenville. It also serves Spartanburg, Anderson, Clemson, Greer, Gaffney, Mauldin, and other Upstate communities.

Greenville residents and businesses may now receive either an 864 or an 821 number because both area codes serve the same geographic territory.

History of the 864 Area Code

The history of area code 864 reflects South Carolina's population growth and rising demand for mobile, business, and internet-based phone numbers.

• 1947: Area code 803 was introduced as South Carolina's original statewide area code.
• 1995: The Upstate region was separated from area code 803 and assigned the new 864 area code.
• December 3, 1995: Area code 864 officially entered service for northwestern South Carolina.
• Following decades: Population growth, additional mobile devices, business phone systems, and VoIP services increased demand for telephone numbers.
• September 27, 2022: The South Carolina Public Service Commission approved an all-services overlay for the 864 numbering area.
• November 28, 2022: NANPA released the official implementation plan for the new 821 overlay.
• January 19, 2024: The permissive 10-digit dialing period began. Calls could temporarily be completed using the old or new dialing method.
• July 19, 2024: Mandatory 10-digit dialing began throughout the 864 region.
• August 19, 2024: Area code 821 officially became available as an overlay for the same territory.

The overlay allowed telephone providers to introduce more numbers without requiring existing customers to change their 864 numbers.

What Is the Overlay Code for 864?

The overlay code for 864 is 821.

An overlay places an additional area code over an existing numbering region. Therefore, 864 and 821 serve the same cities and communities rather than separate sections of the Upstate.

For example, one Greenville resident may have an 864 number, while a new business operating next door may receive an 821 number.

Important facts about the overlay include:

• Existing 864 numbers did not change.
• The geographic boundaries remained the same.
• New customers may receive an 821 number.
• Calls between 864 and 821 numbers are not automatically long-distance calls.
• Ten-digit dialing is required for local calls.

NANPA stated that 821 central-office codes would become available after assignable 864 prefixes were exhausted.

Do You Need 10-Digit Dialing for 864?

Yes. You must use 10-digit dialing when calling a local number in the 864 and 821 region.

The required format is:

• Area code + seven-digit phone number

For example:

• 864-555-0123

Mandatory 10-digit dialing began on July 19, 2024. NANPA's dialing plan specifies 10 digits for local calls and 1 plus 10 digits for toll calls, subject to the caller's service provider.

Residents and businesses should make sure that the full telephone number is programmed into:

• Smartphone contact lists
• Alarm systems
• Medical monitoring equipment
• Call-forwarding systems
• Fax machines
• Security gates
• Automatic dialers
• Business phone menus
• Website contact buttons

The addition of 821 does not change local calling boundaries or the price of a call. It only increases the number of telephone numbers available within the region.

Is the 864 Area Code Legit or a Scam?

The 864 area code is completely legitimate. It is an officially recognized telephone code serving Upstate South Carolina.

However, seeing 864 on caller ID does not guarantee that the caller is physically located in South Carolina or that the call is trustworthy. Scammers can use caller ID spoofing to make a call appear to come from a familiar local number.

The Federal Trade Commission warns that scammers may alter caller ID information to impersonate government departments, banks, businesses, relatives, or other trusted organizations.

You should evaluate the caller's request and behavior rather than trusting the area code alone.

Common 864 Scam Warning Signs

Be cautious when an unknown 864 caller:

• Demands immediate payment
• Threatens arrest, account closure, or legal action
• Requests a password, PIN, or verification code
• Asks for a Social Security number or banking details
• Requires payment through gift cards, cryptocurrency, or wire transfers
• Claims you have won a prize but must pay a fee
• Refuses to let you independently verify the organization
• Pressures you to remain on the phone
• Sends an unexpected payment link
• Claims a relative is in an emergency and needs money immediately

Caller ID may display a real local business or government number even when the call originates elsewhere. The FTC recommends ending suspicious calls and contacting the organization through a verified number obtained independently.

What Are the Common Scams Linked With Spoofed 864 Numbers?

No major scam is exclusive to area code 864. Criminals often choose local-looking numbers because recipients may be more willing to answer them.

Government impersonation scams

The caller may pretend to represent the IRS, Social Security Administration, police department, court, or another government agency. The scammer may threaten arrest or claim that your identity has been connected to illegal activity.

Bank and account-security scams

A caller may claim that your bank account or credit card has been compromised. The objective is usually to obtain login credentials, card details, verification codes, or a payment.

Family emergency scams

The scammer may pretend to be a family member, lawyer, police officer, or hospital worker. You may be told that a relative has been arrested, injured, or stranded and urgently needs money.

Tech-support scams

The caller may claim that your computer, internet connection, or online account has a virus or security problem. They may ask you to install remote-access software or provide payment information.

Prize and lottery scams

You may be told that you won money, a vacation, or another prize. The scammer then requests an upfront processing, delivery, or tax payment.

Fake debt-collection calls

The caller may claim that you owe money and must pay immediately. A legitimate collector should be able to provide written information that allows you to verify the debt.

Robocall and sales scams

An automated message may promote fake insurance, loan relief, warranty coverage, investment opportunities, or other misleading offers. The FTC advises consumers to hang up on illegal robocalls rather than pressing buttons or sharing information.

How to Handle a Suspicious 864 Call

Do not provide personal or financial information during an unexpected call.

Instead:

• End the call.
• Search for the organization's official contact information.
• Call the organization directly using a verified number.
• Block the suspicious caller.
• Save relevant voicemails or messages.
• Contact your bank immediately if financial information was shared.
• Report suspected fraud to the FTC.

The FTC specifically advises consumers not to rely solely on caller ID because the displayed name and number can be spoofed.

What Are the Benefits of an 864 Area Code Number?

An 864 phone number can be useful for businesses and professionals serving Upstate South Carolina.

Stronger local recognition

People in Greenville, Spartanburg, Anderson, and nearby communities immediately recognize 864 as an Upstate South Carolina area code.

Greater customer familiarity

Some customers may feel more comfortable answering a recognizable local number than an unfamiliar out-of-state number.

Regional brand identity

An 864 number can help a business communicate that it serves customers within the Upstate region.

Virtual local presence

A company does not necessarily need a traditional landline to use a local number. Many providers offer virtual numbers that can forward calls to mobile phones, offices, or remote customer-support teams.

Separate business and personal calls

Small-business owners can use an 864 business number without publishing their personal mobile number.

Professional call-management features

Depending on the provider, a local number can include voicemail, call routing, extensions, call recording, business-hour rules, analytics, and text messaging.

How Can an 864 Area Code Number Benefit Your Business's Local SEO?

An 864 number does not automatically improve Google rankings. Google explains that local results are primarily determined by relevance, distance, and prominence, rather than by a business's area code alone.

However, a local phone number can support a broader local marketing strategy in several ways.

Creates a consistent local identity

Use the same business name, address, and phone number across your website, Google Business Profile, social accounts, directories, and citation listings.

Supports customer trust

A familiar 864 number may reassure people that the business serves Greenville or the wider Upstate market.

May improve call conversions

Customers searching for a local contractor, clinic, restaurant, agency, or professional service may be more comfortable calling a recognizable regional number.

Strengthens location pages

An 864 number can be displayed on relevant Greenville or Upstate service pages when it accurately represents the business and its service area.

Improves offline and online marketing consistency

The same number can be used on advertisements, business cards, vehicle graphics, social profiles, and local directory listings.

The number should accurately represent the business. A virtual 864 number should not be used to create misleading locations or fake Google Business Profiles.

Can You Get a New 864 Number Today?

You may still be able to obtain an 864 number, but availability is not guaranteed.

Some mobile carriers, landline providers, and VoIP platforms may have 864 numbers within their available inventory. However, because the 821 overlay is active, a provider may offer you an 821 number when no suitable 864 numbers are available.

The overlay was designed so new 821 numbers could serve the same geographic area once assignable 864 prefixes became limited.

Your chances of obtaining 864 may depend on:

• The service provider
• The city or rate center
• Current number inventory
• Whether you require a specific prefix
• Whether you need mobile, landline, or VoIP service
• Whether you are porting an existing 864 number

An 821 number represents the same geographic market and should not be considered less local than an 864 number.

How Can You Get a New 864 Area Code Number?

You can obtain an 864 number through a mobile carrier, traditional telephone company, business phone provider, or VoIP platform.

1. Choose a telephone provider

Compare mobile, landline, and cloud-phone providers based on pricing, calling features, text messaging, call forwarding, and number portability.

2. Search available numbers

Enter Greenville, Spartanburg, Anderson, or another covered Upstate city when searching the provider's number inventory.

3. Request area code 864

Select 864 as your preferred area code. The provider may display several available numbers or inform you that only 821 numbers are currently available.

4. Select your preferred number

Choose an easy-to-remember number when possible. Some business phone services may also offer vanity or repeating-digit options for an additional cost.

5. Configure your calling features

Set up:

• Call forwarding
• Business voicemail
• Operating hours
• Extensions
• Automated greetings
• Text messaging
• Spam filtering
• Call recording, where legally permitted

6. Update your business information

Add the new number to your website, Google Business Profile, social accounts, email signature, advertisements, and directory listings.

7. Port an existing number when necessary

If you already own an 864 number, ask the new provider whether it can be transferred instead of replaced. Do not cancel the existing service before the porting process is complete.

Final Thoughts

The 864 area code represents Greenville, Spartanburg, Anderson, Clemson, and much of Upstate South Carolina. It was introduced in 1995 after being separated from area code 803 and now operates alongside the 821 overlay.

Existing 864 numbers remain valid, while new customers may receive either 864 or 821 depending on provider inventory. Ten-digit dialing is required throughout the region.

An 864 number can give a business recognizable local branding, but the area code alone does not guarantee better search rankings or establish that an incoming call is safe. Keep business information consistent across online platforms, and always verify unexpected callers before sharing personal information or sending money.

Frequently Asked Questions (FAQs): 864 Area Code

Why was the 821 area code added to the 864 region?

The 821 overlay was introduced because the supply of available 864 phone numbers was running low. Both area codes now serve the same Upstate South Carolina communities.

Is the 864 area code being replaced by 821?

No. Existing 864 numbers will continue working normally and will not be changed. The 821 code simply provides additional numbers for new telephone lines and services.

Do I have to dial 864 when making a local call?

Yes. Callers within the 864 and 821 service area must dial the area code followed by the seven-digit phone number, even when calling someone nearby.

Does 10-digit dialing make an 864 call long distance?

No. Dialing ten digits does not automatically make a call long distance or increase its cost. Calls between local 864 and 821 numbers remain local according to your provider's calling plan.

Is an 821 number less local than an 864 number?

No. The 821 and 864 area codes cover the same geographic region in Upstate South Carolina. An 821 number can be just as local as an 864 number.

Can I still get a new 864 phone number?

Possibly, but availability depends on your telephone or VoIP provider's inventory. Because 821 is now active, new customers may receive an 821 number when no suitable 864 numbers are available.

Why am I receiving suspicious calls from 864 numbers?

Scammers often use "neighbor spoofing" to display a phone number with your local area code. The call may appear to come from Upstate South Carolina even when the scammer is located somewhere else.

Does an unknown 864 number mean it is a scam?

Not necessarily. Many legitimate residents and businesses use 864 numbers, but the area code alone cannot confirm a caller's identity because caller ID information can be faked.

Should I call an unknown 864 number back?

Check whether the caller left a legitimate voicemail before returning the call. Never call back using a number provided in a suspicious message; instead, find the organization's official number independently.

What should I do with a suspicious 864 call?

Hang up without sharing passwords, verification codes, banking details, or personal information. Block the number and report suspected fraud to the FTC, especially if you lost money.
