Xfinity availability: where Comcast reports internet service

Is Xfinity available in your state?

As of June 30, 2026 (FCC revision of November 10, 2026), Xfinity, filed with the FCC under Comcast Corporation, reports service at 39,093,708 broadband serviceable locations: the FCC's term for each house, apartment building and small business that could get service. Its five largest states by locations are Florida (3,825,081), California (3,569,062), Pennsylvania (3,340,940), Illinois (2,822,979) and Michigan (2,194,654¹).

Size and share tell different stories. Florida has the most Xfinity locations, yet they make up 49.4% of the state. Other places are covered far more completely: the District of Columbia at 99.3%, Maryland at 87.5%, Massachusetts at 83.1%, Delaware at 79.7%, Utah at 74.5% and Colorado at 74.0%. In Texas Xfinity reaches 20.3% of locations, in California 34.7%¹.

Xfinity is listed in 41 states, DC included, but the count says little about reach. It reports 0.1% of locations in North Carolina, 0.1% in Rhode Island, 0.7% in New York, 1.2% in Wisconsin and 2.0%¹ in Ohio: small pockets, not statewide service. A claim that Xfinity serves every state does not hold for residential service; the state table shows where the footprint really is.

Cable nearly everywhere, fiber in a few places

Xfinity's network is overwhelmingly cable. It reports cable at 37,980,036 locations, the largest cable footprint of any provider, ahead of Spectrum at 34.0 million. The advertised tier hardly varies: at 37,980,036 of those locations Xfinity reports at least 100 Mbps download and 20 Mbps upload, and its fastest advertised cable download is 2 Gbps¹.

Technology	Locations	At 100/20 Mbps or more	Fastest advertised download (Mbps)
Fiber	1,121,576	1,121,576	2,000
Cable	37,980,036	37,980,036	2,000

Fiber is the smaller and newer part. Xfinity reports fiber to the premises at 1,121,576 locations, with advertised downloads up to 2 Gbps, against 23.5 million for AT&T¹. Of those fiber locations, +1,099,749³ were added between June 2022 and June 2026, so in the first National Broadband Map Xfinity fiber barely registered.

The fiber is not spread evenly. In Connecticut Xfinity reports fiber at 10.3% of all locations, its highest share of any state, followed by New Mexico (4.4%), Maryland (3.2%) and Florida (3.1%). A few cities stand out: Xfinity reports fiber at 88.3% of locations in Rio Rancho, New Mexico, 55.7% in Bridgeport, Connecticut, and 41.1% in Coral Springs, Florida. In those three cities fiber, not cable, is most of what Xfinity reports. In most large cities the share is far lower; in Philadelphia, where Xfinity reports 501,023 locations, it is 0.0%¹.

Covered is not the same as competing

For someone choosing a home, a more useful Xfinity number than coverage is how often it faces no wired competition. At 12,657,596 locations, nearly a third of its footprint, Xfinity is the only wired provider reporting 100/20 Mbps. The figure for Spectrum, the other national cable network, is similar (12,749,844); for AT&T it is 483,552¹. Fixed wireless and satellite may still be offered at these addresses, but no second cable or fiber line at that speed is reported.

The share varies by state. Xfinity is the only wired 100/20 option at 38.1% of New Mexico's locations (in Albuquerque, 61.4%), 34.5% of Washington's and 32.2% of Massachusetts's. In Connecticut, where it has the most fiber, the figure is 10.0%¹.

Cities make the contrast sharper, because Xfinity covers almost every location in many of them. In Boston it reports 99.8% of locations and is the only wired 100/20 provider at just 8.3%; Verizon also reports fiber at 86.6% of the city. In Quincy, next door, Xfinity's coverage is the same (99.9%), Verizon fiber reaches 8.8%, and Xfinity is the only wired 100/20 provider at 90.1% of locations. New Bedford goes furthest: 99.9%. Philadelphia resembles Boston (4.3%), while Detroit (63.8%) and Baltimore (81.6%¹) sit in between.

The table counts wired choices at 100/20 Mbps among all providers. In every city listed, Xfinity reports service at more than nine in ten locations, so a high share with one wired choice there means, in practice, Xfinity alone.

Growth since 2022

Between June 30, 2022 and June 30, 2026, Xfinity's reported footprint grew by 3,012,460³ locations; in the last six months alone, since December 31, 2025, it grew by 307,057, of which +181,068⁴ were fiber. Not all of that is new network. The FCC's own list of locations grew by 3,495,329¹ over the same four years, as new buildings were added and records corrected, so a provider can gain locations without laying cable. The state table above shows the change state by state. The largest gains are in Florida and Texas, the two states with the most Xfinity fiber locations.

Cities where Xfinity reaches the most locations

Among the 343 cities of 100,000 or more, Xfinity reports its highest shares in Massachusetts and New Hampshire, followed by cities from the Twin Cities and Michigan to Pennsylvania, Northern Virginia, the Denver area and South Florida, each at or near full coverage.

Florida shows how local the footprint is. It is Xfinity's largest state, and the company reports 99.9% of locations in Fort Lauderdale and 99.8% in Miami. In Orlando it reports 0.9%; there Spectrum covers 89.3%¹. Knowing the state is not enough; the city decides.

What these figures are, and are not

Every number on this page comes from Xfinity's own filing with the FCC for June 30, 2026. "Available" means Xfinity says it could connect a location within ten business days with a standard installation; anyone can challenge a listing on the FCC National Broadband Map. Speeds are maximum advertised speeds, not measurements. The filings contain no prices: those are on the broadband facts label that the FCC requires Xfinity to show for each plan.
