## How precisely can a proxy target South Carolina?

**South Carolina has 5.57 million residents (2025 Census estimate); one FiftyStateProxy username reaches all of South Carolina, only Charleston, or a single South Carolina ZIP code.** The four levels:

- **All of South Carolina:** `state-sc`.
- **Charleston:** `state-sc-city-charleston`.
- **One ZIP:** `zip-` plus a South Carolina ZIP from 290–299.
- **One network:** `asn-` plus a South Carolina AS number such as AS7922 Comcast.

[How to set up a US proxy](https://fiftystateproxy.com/how-to-set-up-a-us-proxy/ "How to set up a US proxy") shows where the South Carolina username goes in each tool; [what ZIP code proxy targeting does](https://fiftystateproxy.com/what-is-zip-code-proxy-targeting/ "ZIP code proxy targeting explained") covers ZIP-level South Carolina sessions.

### Which South Carolina city ids does the gateway accept?

| South Carolina city | Username parameter |
| --- | --- |
| Charleston | `city-charleston` |
| Columbia | `city-columbia` |
| North Charleston | `city-north_charleston` |
| Mount Pleasant, Rock Hill and smaller towns | `zip-` + a local ZIP |

Availability per South Carolina city varies with how many homes are online.

## Which home ISPs and ASNs sit behind South Carolina residential IPs?

**The home networks most often behind South Carolina IPs are AS20115 Charter and AS7018 AT&T, per public routing registries.** BroadbandNow lists Spectrum (Charter), AT&T Fiber, Xfinity (Comcast) among South Carolina home-internet providers; each South Carolina exit IP carries the ASN of its ISP:

- AS20115 Charter
- AS7018 AT&T
- AS7922 Comcast
- AS12083 WOW!
- AS21928 T-Mobile

These are registry facts about South Carolina networks, not FiftyStateProxy IP counts. `-asn-` keeps a long South Carolina crawl on Xfinity (Comcast) alone. Mobile networks in South Carolina: T-Mobile, AT&T, Verizon; FiftyStateProxy [4G/5G carrier ports](https://fiftystateproxy.com/us-mobile-proxies/ "Dedicated T-Mobile, AT&T and Verizon 4G/5G ports") are sold US-wide, not per state.

## What do teams check from a South Carolina IP address?

Teams rent South Carolina IPs to load public pages as South Carolina households see them:

- Tracking public vacation-rental and golf-travel pricing in Myrtle Beach, Charleston and Hilton Head
- Monitoring auto dealer inventory and pricing in the Upstate (Greenville–Spartanburg) manufacturing corridor
- Local SEO for home-services firms in the fast-growing Charleston and Columbia markets

An ad audit in a South Carolina DMA such as Greenville–Spartanburg–Asheville–Anderson needs a city id or ZIP inside that market. A South Carolina landing page that shows none of the area codes 803, 821, 839, 843, 854, 864 is serving the wrong local number. Charleston rank tracking follows [how to track local rankings by ZIP code](https://fiftystateproxy.com/best-us-proxies-for-local-seo/ "Best US proxies for local SEO"); South Carolina price checks follow [which proxies suit price monitoring](https://fiftystateproxy.com/best-us-proxies-for-price-monitoring/ "Best US proxies for price monitoring").

South Carolina keeps Eastern time, so one schedule covers every South Carolina city id and ZIP.

## What does South Carolina proxy traffic cost?

A 1 GB plan for Charleston or any South Carolina ZIP costs $1.50, ASN targeting included. **At $0.52/GB, 1 TB costs 65% less per GB than the 1 GB plan** (October 2026). See [how much US residential proxies cost](https://fiftystateproxy.com/pricing/ "US residential proxy prices per GB").

## Which other South Atlantic states can I target?

Swap `state-sc` for another code; [all 50 states and Washington, D.C.](https://fiftystateproxy.com/us-residential-proxies/#states "US residential proxies by state") cost the same as South Carolina.

## What else do buyers ask about South Carolina proxies?

### Is Charleston included when I buy South Carolina residential proxies?

Yes. Every plan covers all of South Carolina, and `city-charleston` limits a session to Charleston at no extra cost. Columbia and North Charleston have city ids on the same plan.

### Can I target any ZIP code in South Carolina?

Yes: any five-digit ZIP starting with 290–299. A sparsely populated South Carolina ZIP returns fewer IPs than a dense one in Charleston, so keep `city-charleston` as a fallback.

### Which South Carolina ISP should I pick for ASN targeting?

The one your audience uses. Besides Spectrum (Charter), South Carolina homes connect through Xfinity (Comcast) and HTC (Horry Telephone Cooperative); their AS numbers are listed above. Test the chosen South Carolina network on the 1 GB plan ($1.50) first.

### Which TV markets can I audit with South Carolina IPs?

The DMAs covering South Carolina include Greenville–Spartanburg–Asheville–Anderson · Columbia, SC · Charleston, SC · Myrtle Beach–Florence. Use a ZIP inside each South Carolina market you compare.

### Is a residential proxy legal to use in South Carolina?

Generally yes, as long as each South Carolina job respects the target site's rules, US computer-crime and anti-spam law, and our [acceptable use policy](https://fiftystateproxy.com/acceptable-use/ "FiftyStateProxy acceptable use policy"). This is general information, not legal advice.
