Fiber internet in the United States

What the map counts

A location counts as having fiber when at least one provider tells the FCC it offers fiber-to-the-premises service there, with installation possible within ten business days. It is a statement about the network, not about what anyone subscribes to: the Census Bureau's surveys cannot separate fiber subscriptions from cable or DSL. Shares are of the FCC's broadband serviceable locations (houses, apartment buildings and small businesses), with data as of June 30, 2026 in the FCC revision of November 10, 2026.

Where fiber is common, and where it is rare

Fiber is most widespread in the District of Columbia, at 87.4% of locations, followed by Rhode Island (86.2%) and Hawaii (82.7%). At the other end, fiber reaches 17.1% of locations in Alaska and 36.4% in New Mexico. In 40¹ of the 50 states and DC, fiber is available at half of all locations or more.

The county map shows the finer grain. Fiber is not simply an urban technology: many of the highest county shares are in rural North Dakota, South Dakota and Tennessee, while some large suburban counties are still mostly served by cable.

How fast it is spreading

Between June 2022 and June 2026 the national share rose by 25.4 percentage points, and by 2.7 percentage points in the last six months of that span alone. The largest four-year gain among the states was in Maine (+48.4 percentage points), then Hawaii (+41.7 percentage points) and Wyoming (+41.3 percentage points¹). The fiber growth ranking has every state.

Who builds it

1,461 brands report fiber somewhere in the country. The largest footprint is AT&T's, at 23.5 million locations (20.3% of all US locations), followed by Verizon (9.5 million) and Frontier (6.9 million¹). Below the national companies sit hundreds of regional telephone companies, cooperatives, municipal utilities and new fiber builders, which is why the count of fiber providers in a single state can run into the dozens.

Fiber in the largest cities

Large cities are better wired for fiber than the country as a whole. Across the 343 cities with 100,000 people or more, the median share of locations with fiber is 74.0%, and 258 of them have fiber at half of their locations or more. At the top of the list, Clarksville, Tennessee, Chattanooga, Tennessee and Lincoln, Nebraska are at 100.0%, 100.0% and 99.9%. At the bottom, fiber is reported at 0.0% of locations in New Bedford, Massachusetts, 0.5% in Cambridge, Massachusetts and 2.0% in Albany, New York¹. The fiber ranking of cities lists all of them, with ties.

A second fiber network is still unusual

Where fiber exists, it usually comes from one company. Only 12.1%¹ of US locations have two or more different fiber providers, though that is up from 3.1%² in June 2022. A second fiber network laid where one already exists is called overbuild; the city pages show where it happens.

What fiber changes for a household

Two measures in the FCC data move with fiber. Upload speed: wired service with at least 100 Mbps in both directions is reported at 73.7% of locations, more than the 62.6% with fiber, because some cable networks now also file uploads of 100 Mbps. Multi-gigabit tiers: an advertised download of 2 Gbps or more is the fastest offer at 61.0%¹ of locations, against 13.3%² in June 2022, as fiber builders and some cable operators raised their top tiers.

What the data cannot say is how well a given network performs, what it costs or whether a building's wiring is ready. Those questions belong to the provider and, for prices, to its broadband facts label.

Fiber and the federal money

Fiber is also the main technology of the federal Broadband Equity, Access, and Deployment (BEAD) program. In the state final proposals summarized by NTIA, 2,368,238 of the 3,772,113 locations are assigned to fiber, 829,696 to low-Earth-orbit satellite and 499,177⁵ to fixed wireless; the BEAD ranking compares the states. Each state page shows its own plan's technology mix.
