Our area codes include:

Area code 803 location: Where is it, and what cities does it cover?
Area code 803 is located in central South Carolina and covers some of the state’s most prominent cities, including Columbia, Rock Hill, Sumter, and Aiken. One of the original area codes established in 1947, 803 is deeply rooted in South Carolina’s identity and history.

Due to the growth of the region and increasing demand for phone numbers, area code 839 was introduced as an overlay in 2020. Both 803 and 839 now serve the same geographic area, and 10-digit dialing is required for all local calls.
Columbia, the state capital and largest city in the 803 area, is home to the University of South Carolina and the Fort Jackson Army base. It’s a center of government, education, and culture. Rock Hill, part of the Charlotte metro area, is a booming suburb with growing business and residential developments. Sumter and Aiken bring a mix of military presence, manufacturing, and Southern charm to the region.

Area code 803 also serves surrounding counties such as Lexington, Richland, York, and Orangeburg. From historic downtowns to vibrant college campuses and growing suburbs, the 803 area code reflects a blend of tradition, progress, and Palmetto State pride.

Whether you’re calling a government office in Columbia, a business in Rock Hill, or a military family in Sumter, a 803 number is a trusted part of South Carolina’s communications backbone.

Bordering area codes include 843 to the southeast (covering Charleston and Myrtle Beach), 864 to the northwest, and 980/704 just across the North Carolina state line.

Area code 821 location: Where is it, and is it the same as 864?
Area code 821 is located in Upstate South Carolina and serves the same geographic region as area code 864, including major cities like Greenville, Spartanburg, Anderson, Clemson, Greenwood, and Laurens. Introduced in 2024 as an overlay, 821 was added to keep up with the rising demand for phone numbers in one of South Carolina’s fastest-growing regions. Both area codes now operate in the same area, and 10-digit dialing is required for all local calls.

Area code 864 has long been associated with Upstate SC since its creation in 1995, covering a region known for its blend of Southern charm, economic development, and natural beauty. As the area expanded—with booming suburbs, growing industries, and top-tier universities—821 was introduced to ensure continued number availability.

The 821 region includes Greenville, a vibrant city with a thriving downtown and rapidly growing tech, healthcare, and manufacturing sectors. Spartanburg is home to several major corporate headquarters and colleges, while Anderson and Greenwood offer a mix of historic charm and modern commerce. Clemson, with its nationally recognized university and Tiger pride, brings energy and innovation to the region.

From scenic mountain views to business-friendly communities, the 821 area code represents a forward-looking Upstate South Carolina. Whether you’re calling a startup in Greenville, a student in Clemson, or a small business in Laurens, a 821 number means you’re connected to the economic heart of the Palmetto State.
821 is bordered by other area codes such as 803/839 to the southeast and 828/704 just across the North Carolina border to the north.

Area code 839 location: Where is it, and is it the same as 803?
Area code 839 is located in central South Carolina and serves the same geographic region as the long-established 803 area code. Introduced in 2020 as an overlay, 839 was created to meet the growing demand for phone numbers in a region that includes major cities such as Columbia, Rock Hill, Sumter, Aiken, and surrounding communities.

Originally established in 1947, area code 803 is one of South Carolina’s three original area codes. As population and economic growth surged—particularly around the Columbia metropolitan area and Charlotte suburbs like Rock Hill—the need for more phone numbers led to the implementation of area code 839. Today, both area codes are active in the same region, and 10-digit dialing is required for all local calls.

The 839 area code covers Columbia, the state capital and a center of government, education, and healthcare. It also includes Rock Hill, a rapidly expanding city just south of Charlotte, and Sumter, home to Shaw Air Force Base. The region is known for its blend of Southern charm, military presence, economic opportunity, and historical significance.

In addition to urban centers, the 839 overlay serves rural counties and growing suburban areas like Lexington, Orangeburg, Kershaw, and Newberry, making it an essential part of the state’s communication infrastructure.

Whether you’re calling a business in downtown Columbia, a manufacturing facility in Aiken, or a university in Rock Hill, a 839 number keeps you connected to the heart of the Palmetto State.

839 borders other area codes like 843/854 to the southeast (Charleston and coastal SC), 864/821 to the northwest (Upstate SC), and 704/980 just across the North Carolina border.

Area code 843 location: Where is it, and is it the same as 854?
Area code 843 is located in coastal South Carolina, covering iconic destinations like Charleston, Myrtle Beach, Hilton Head Island, Florence, and Beaufort. Introduced in 1998 as a split from the 803 area code, 843 quickly became synonymous with South Carolina’s Lowcountry and Grand Strand regions—renowned for their history, tourism, and Southern charm.

As the area experienced rapid growth in population, tourism, and mobile devices, area code 854 was added in 2015 as an overlay to 843. Both area codes now serve the same region, and 10-digit dialing is required for all local calls.

843 is the area code of Charleston, the state’s oldest city, famous for its cobblestone streets, historic architecture, and vibrant culinary scene. Myrtle Beach, part of the Grand Strand, draws millions of visitors annually with its resorts, golf courses, and beachfront attractions. Hilton Head Island offers world-class golf, upscale communities, and protected natural beauty. Inland cities like Florence and Conway also fall within the 843/854 zone, playing vital roles in healthcare, education, and logistics.

Whether you’re booking a hotel in Charleston, reaching a local business in Myrtle Beach, or calling a family home in Beaufort, a 843 number connects you to the heart of South Carolina’s coast—where history, hospitality, and modern living meet.
843 borders area codes 803/839 to the west and 912 to the south across the Georgia border.

Area code 854 location: Where is it, and is it the same as 843?
Area code 854 is located in coastal South Carolina and serves the same region as the well-known 843 area code. Introduced in 2015 as an overlay, 854 was added to meet the growing demand for new phone numbers in a region known for its booming tourism, population growth, and economic development. Both 854 and 843 now cover the same area, and 10-digit dialing is required for all local calls.

The 854 area includes major coastal destinations such as Charleston, Myrtle Beach, Hilton Head Island, Florence, Beaufort, and Conway. It represents South Carolina’s Lowcountry and Grand Strand, areas rich in history, natural beauty, and Southern charm.

Charleston, often ranked as one of the best cities in the U.S., blends colonial history with a vibrant food, tech, and arts scene. Myrtle Beach, part of the Grand Strand, is a top vacation destination known for its resorts, golf, and oceanfront boardwalks. Hilton Head offers luxury living, world-class golf, and serene beaches. Inland, cities like Florence and Conway provide essential hubs for healthcare, education, and industry.

Whether you’re calling a resort in Hilton Head, a business in Charleston, or a university in Conway, a 854 number signifies a connection to South Carolina’s coastal backbone—an area defined by growth, beauty, and tradition.
Area code 854 borders 803/839 to the west and 912 just across the Georgia border to the south.

Area code 864 location: Where is it, and does it share a region with 821?
Area code 864 is located in Upstate South Carolina, covering major cities like Greenville, Spartanburg, Anderson, Clemson, Greenwood, and Gaffney. Established in 1995 as a split from the original 803 area code, 864 has become a defining feature of the state’s fast-growing northwest region.

Due to continued growth in population, business, and mobile usage, area code 821 was introduced in 2024 as an overlay to 864. Both area codes now serve the same region, and 10-digit dialing is required for all local calls.

Greenville, the largest city in the 864 area, is known for its revitalized downtown, strong job market, and booming tech and manufacturing sectors. Spartanburg is home to multiple colleges and global manufacturers, including BMW’s North American plant. Anderson, often called “The Electric City,” blends innovation and Southern hospitality.
