Cox Internet is a well-known internet provider offering multi-gig cable and some fiber internet in 18 states. Cox's fiber locations are currently undisclosed. However, Cox uses fiber-optic cables to supplement its cable infrastructure, and the company has announced that it’s committed to providing fiber-only service in underserved areas.

You can check if Cox is available near you using our zip search bar above. To see if you can get fiber specifically, you should contact Cox directly at 1-800-234-3993. Cox has yet to release any fiber coverage maps or checker tools.

I’ve written a lot about Cox Internet and spent (maybe too much) time engaging with FCC maps and proprietary data. Here’s what I’ve learned in this deep dive into Cox coverage and availability.

Cox Internet is a mainly cable service in parts of the South, Midwest, and West and East Coasts. Overall, the provider’s coverage is a bit limited—this isn’t one of those internet services you can buy in one state and take with you when moving across the country. And if you want fiber internet from Cox instead of cable, coverage areas are even more limited. (Uniquely, Cox focuses on bringing its fiber to underserved areas rather than the big cities typically associated with fiber internet.)

But for folks who’ve found their forever homes or don’t mind switching internet service when they move, Cox Internet’s coverage is perfect.

Top 10 cities where you can get Cox Internet

Live in a big city and want to get Cox Internet? Here are the ten biggest cities where Cox service is available.

How is Cox Internet expanding internet service?

Cable internet is often excellent, but fiber-optic internet is all the buzz, and Cox knows it.

Although Cox’s cable service is still going strong, the telecom company is enriching its cable lines with fiber-optic connections. Cox also offers limited FTTH service, with more on the way in rural areas.

“Cox is continuing its commitment to digital equity by expanding its fiber-to-the-home network to rural and hard-to-reach areas that previously lacked an adequate broadband connection,” Cox announced in July 2024.

The company also expanded its fiber service “to reach over 60,000 households in Arizona, Florida, Kansas, Nebraska, Oklahoma, and Virginia that were previously unserved or underserved.”

What are other internet options besides Cox Internet?

Cox isn’t the only internet provider in its service areas, which cover some of the most populous cities in the U.S.

Cox Internet crosses paths with one of the top cable internet providers in the nation: Spectrum. Spectrum has the advantage of being a little less expensive and far more widely available than Cox, but Cox ranks above Spectrum in terms of average user speed. 

Cox also runs up against Frontier, which offers old-school DSL and new-school fiber. While Frontier has a larger fiber footprint than Cox, Cox’s cable speeds far exceed Frontier’s poky DSL. 

With the largest coverage areas in the nation, T-Mobile 5G Home Internet and Verizon 5G Home Internet share most of Cox’s territory. These 5G providers aren't just readily available, but they're also pretty cheap. That being said, they work over a wireless connection, which means they may not be as reliable as a hardwired internet option like Cox.
