Cox availability: a regional cable network from Arizona to Rhode Island

Is Cox available in your state?

As of June 30, 2026 (FCC revision of November 10, 2026), Cox reports service at 7,379,622 broadband serviceable locations, the FCC's term for each house, apartment building or small business that could get a connection. It files with the FCC as Cox Communications, Inc. The count covers 18¹ states, but in several of them Cox lists only a few thousand locations or fewer.

Measured by the share of a state's locations, Cox's core is small and dense. It reports service at 92.6% of Rhode Island's locations, 63.9% of Arizona's and 64.7% of Nevada's. A second tier runs through the southern Plains and the Gulf: Oklahoma (41.6%), Louisiana (37.2%), Kansas (34.9%) and Nebraska (30.9%). In Virginia (27.5%¹) its large cities are in Hampton Roads: Virginia Beach, Norfolk, Chesapeake and their neighbors.

California is Cox's second-largest state by count, 809,591 locations, yet that is 7.9% of the state; its large California cities are in San Diego and Orange counties. Florida (3.9%), Georgia (3.1%), Connecticut (12.8%) and Arkansas (17.4%) follow the same pattern of a few metro areas inside a larger state. Below them the filing thins to Ohio (82,574 locations), Iowa (26,084) and Idaho (9,850), then to North Carolina (2,437), Massachusetts (1,478), Missouri (4) and the District of Columbia (1¹).

Cable at 100/20 almost everywhere, fiber on top

Cox reports cable at 6,480,640 locations, behind only Xfinity (38.0 million) and Spectrum (34.0 million). The advertised tier is uniform: 6,480,628 of those locations are filed at 100 Mbps download and 20 Mbps upload or more, and the fastest advertised cable download is 2 Gbps¹.

Fiber to the premises is reported at 893,902 locations, also at up to 2 Gbps. That is a fraction of the largest fiber footprints (AT&T files 23.5 million), but it is the part of Cox's network that is changing. The rest is marginal: licensed fixed wireless at 3,861 locations, unlicensed fixed wireless at 1,620 and DSL at 3¹. A location can be counted under more than one technology.

Cox fiber is concentrated in Arizona

Cox's fiber is not spread across its footprint. In Arizona it reports fiber at 15.4% of all the state's locations; in Nevada the figure is 11.1%, in Rhode Island 7.2%, in Oklahoma 5.8%. In Virginia (1.1%), Louisiana (0.9%) and California (0.5%¹) Cox remains almost entirely a cable network.

Within Arizona, the fiber is densest at the western edge of metro Phoenix. Cox reports fiber at 57.2% of locations in Goodyear, 53.6% in Buckeye and 47.2% in Surprise, against 17.1% in Phoenix itself and 2.4% in Tucson. Counting every provider, fiber reaches most locations in those three cities: 79.2%, 88.3% and 87.4%. Statewide, the share of Arizona's locations with fiber from at least one provider rose from 14.4%³ in June 2022 to 41.5%¹.

Growth since 2022

Between June 30, 2022 and June 30, 2026, Cox's reported footprint grew by 65,826 locations. Its fiber count grew by more, +503,061³. The fiber gain can only exceed the total gain if part of the new fiber was reported at locations Cox already listed in 2022, or if Cox stopped reporting other locations; the FCC data do not say which.

In the latest six months, since December 31, 2025, the footprint changed by +67,033 locations and the fiber count by +40,884⁴. Not every added location is new network. The FCC's own list of locations grew by 3,495,329¹ over the four years, through new construction and corrected records, so a provider's count can rise without new lines. The state table above shows the change in each state since June 2022.

Where Cox is the only wired choice

At 2,746,445¹ locations, more than a third of its footprint, Cox is the only wired provider reporting 100/20 Mbps. Fixed wireless and satellite may still be offered there, but no second cable or fiber line at that speed is filed. The share depends far more on the metro area than on Cox itself.

The desert Southwest is where Cox most often stands alone. It is the only wired 100/20 provider at 42.9% of Nevada's locations and 37.6% of Arizona's. In Tempe the figure is 83.1%: the other wired network there, CenturyLink, reports DSL. In the Las Vegas valley it is 60.5% in Las Vegas, 69.7% in Henderson and 71.3% in North Las Vegas; in Tucson, 55.1%¹.

The Plains cities look different, although Cox covers them just as completely. In Omaha and Wichita, where Cox reports more than nine in ten locations, fiber from any provider reaches 88.2% and 90.3% of locations, little of it from Cox, and Cox is the only wired 100/20 provider at 10.5% and 7.1%. Tulsa sits between the two patterns (22.7%¹).

The table counts all providers, not only Cox. In each of these cities Cox reports service at more than nine in ten locations, so a high share with one wired choice at 100/20 Mbps means, in practice, Cox alone.

Rhode Island, covered almost entirely

Rhode Island is the one state where Cox reaches nearly every location (92.6%). It is also a state with wide wired competition: Verizon reports fiber at 80.4% of Rhode Island's locations, and Cox is the only wired 100/20 provider at 12.3%. In Providence, Cox's coverage is 92.9% and its sole-provider share 6.4%¹.

Large cities with the widest Cox coverage

Among the 343 cities of 100,000 or more, Cox reports its highest shares in Las Vegas, Omaha and Irvine (96.9%¹ each), followed by cities in Kansas, Oklahoma, Hampton Roads and Louisiana. The table lists Cox's coverage and technologies city by city.

Cox, Charter and Spectrum

Charter Communications, the company behind the Spectrum brand, announced on August 20, 2026 that it had completed its transaction with Cox Communications, that it will continue to operate as Spectrum across all markets, and that within a year it will rename its parent company Cox Communications. The FCC figures here describe service as of June 30, 2026, before the closing, when Cox filed under its own provider ID. Spectrum is counted separately, at 36.4 million¹ locations. If later FCC releases file Cox's network under Charter, both pages will change with them.

These are availability figures Cox reported to the FCC, not subscriber counts, and they say nothing about prices or plans, which Cox must show on its broadband facts labels. Where a listing is wrong, it can be challenged on the FCC map.
