Where Frontier reports fiber and DSL service

Frontier's footprint on the FCC map

In the National Broadband Map as of June 30, 2026 (file revision of November 10, 2026), Frontier lists 8,661,416 broadband serviceable locations: houses, apartment buildings and small businesses where it says it could install service within ten business days. That is 7.5% of all 115,784,915 US locations, spread over 26¹ states. The filer is Frontier Communications Corporation, and the only brand it files under is Frontier.

By count, the footprint is concentrated in three large states: California (1,883,605 locations), Florida (1,234,601) and Texas (965,321). By share, two smaller states stand apart. Frontier reports service at 80.3% of all locations in Connecticut and 48.3%¹ in West Virginia; in no other state does it reach a fifth.

A state's color on the map says little about a particular street. Frontier reports 1,883,605 locations in California, more than in any other state, yet that is 18.3%¹ of California's total. The FCC National Broadband Map shows the filing for any single address, and a listing that looks wrong can be challenged there.

Fiber or DSL: two answers to "is Frontier available"

Frontier files two technologies, and they sit at opposite ends of the speed range.

• Fiber to the premises: 6,941,829 locations, with advertised downloads up to 7 Gbps. Nearly all of them (6,940,324) are filed at 100/20 Mbps or more. This is the third-largest fiber footprint in the FCC data, after AT&T (23.5 million) and Verizon (9.5 million).
• DSL over copper telephone lines: 2,007,454 locations, with advertised downloads up to 200 Mbps. Just 10¹ DSL locations in the whole filing reach 100/20 Mbps.

Technology	Locations	At 100/20 Mbps or more	Fastest advertised download (Mbps)
Fiber	6,941,829	6,940,324	7,000
DSL (copper)	2,007,454	10	200

A location can appear in both counts. For a reader, the practical point is that a Frontier listing at 100/20 Mbps is, with almost no exceptions, a fiber listing, and a Frontier listing below that speed is DSL. The FCC map shows which of the two Frontier filed at an address.

Mostly fiber in some states, mostly copper in others

Comparing Frontier's overall share of a state with its fiber share shows how different the network is from place to place.

• Nearly all fiber: in Florida, Frontier reports service at 15.9% of locations and fiber at 15.9%. Texas (9.3% and 9.1%), California (18.3% and 17.7%) and Connecticut (80.3% and 76.4%) are close behind.
• A mix: in Indiana the figures are 18.8% and 13.7%; in West Virginia 48.3% and 35.0%; in Ohio 9.0% and 5.9%.
• Mostly DSL: in Minnesota Frontier reports service at 7.8% of locations but fiber at 2.0%; in Wisconsin 10.0% against 3.7%; in Illinois 11.5% against 5.7%¹.

The smaller Frontier states in the West and the Plains are almost entirely copper. In Arizona, Nevada, Nebraska and Iowa the filing lists only a few hundred fiber locations or fewer, and in Alabama, Utah, Mississippi and New Mexico none at all. The table gives every state, with fiber counted separately and the change since the first National Broadband Map of June 30, 2022.

Fewer locations than in 2022, millions more with fiber

Between June 30, 2022 and June 30, 2026, Frontier's reported footprint changed by −92,246 locations, while its fiber footprint grew by 3,073,393³. Since the total fell as fiber rose, the number of locations where Frontier reports DSL but no fiber fell by more than its fiber footprint grew.

The state table shows where each movement happened. Frontier reports more locations than in 2022 in Texas, Connecticut, Pennsylvania, Florida and California, and fewer in most of its other states, among them Indiana, Illinois, West Virginia, Ohio, New York, Michigan and Arizona. In the latest six months, since December 31, 2025, the footprint grew by 277,748 locations and fiber by +395,877⁴.

These are differences between two filings, not a record of construction. The FCC revises its list of locations with every release, and a provider can add or drop locations from its filing for reasons other than building or retiring lines.

Connecticut and West Virginia, where Frontier is a statewide network

In Connecticut, Frontier is the provider reported at the most locations (80.3%), and it files fiber at 76.4% of the state. Across all providers, the share of Connecticut locations with fiber went from 47.4% in June 2022 to 82.1%, while the share with any DSL fell from 62.5%³ to 13.4%. Connecticut's share of locations with two or more fiber networks, 40.2%, is the highest in the country. Besides Frontier, GoNetspeed reports fiber at 28.8% of the state's locations, Optimum at 18.2% and Xfinity at 10.3%¹, so in much of the state a second fiber line runs beside Frontier's. The FCC data do not split these statewide shifts by provider.

West Virginia is less uniform. Frontier reports service at 48.3% of the state's locations, second only to T-Mobile's fixed wireless, but its fiber covers 35.0%; the remainder of its West Virginia footprint is DSL below 100/20 Mbps. Statewide, the share of locations with any DSL fell from 57.9% to 15.1% over the four years, and the share with fiber rose from 14.0%³ to 47.0%. West Virginia still has the 2nd highest share of unserved locations of any state (11.4%¹), the BEAD program's term for locations with no wired or licensed fixed wireless service at 25/3 Mbps.

Where Frontier is the only wired choice

At 243,363 locations, Frontier is the only wired provider offering 100/20 Mbps. Relative to the state, these are far more common in West Virginia, at 6.0% of all locations, than anywhere else Frontier operates: the figure is 0.6% in Texas and 0.3% in California. Among large cities the highest shares are in Menifee (1.8%), Denton (1.2%) and Murrieta (0.9%¹). In every other large city where Frontier files, its share as the only wired provider is lower.

Large cities: nearly all or nearly nothing

In large cities Frontier tends to cover almost every location or almost none, and the two kinds of city often sit side by side.

• Dallas–Fort Worth: Frontier reports fiber at 88.5% of locations in Carrollton, 85.4% in Plano and 79.9% in Garland, but service at 1.1% in Dallas, 6.3% in Frisco and 0.4% in Richardson.
• Southern California: 82.5% of locations in Long Beach and 92.2% in Temecula, against 17.2% in Los Angeles and 11.2% in Fontana.
• Tampa Bay: 87.0% in Tampa, 50.8% across the bay in St. Petersburg.
• Connecticut: in Bridgeport, New Haven and Waterbury, Frontier reports service at 87.6%, 84.3% and 85.9%¹ of locations.

Where Frontier covers a city, copper still separates its overall share from its fiber share in a few places. In Rochester, New York, Frontier reports service at 42.4% of locations and fiber at 31.1%; in Durham, North Carolina, 69.1% and 49.7%. The fastest advertised fiber download is 7 Gbps in most cities, but 5 Gbps¹ in Riverside, Palmdale, Conroe and Tyler.

Among the 343 cities of 100,000 or more, these are the twenty where Frontier reaches the largest share of locations:

Frontier and Verizon

Verizon's annual report on Form 10-K for 2025 states that it completed the acquisition of Frontier Communications on January 20, 2026. The FCC data as of June 30, 2026 still carry Frontier as a separate filer, so this page and the Verizon page count the two networks separately. Verizon's own fiber, sold as Fios, lies mostly from Virginia to Massachusetts; Frontier's largest fiber states are California, Florida, Texas and Connecticut. If a later FCC release lists Frontier's network under Verizon, the figures here will change with it.

Everything on this page is availability as Frontier reported it to the FCC, as of June 30, 2026: maximum advertised speeds, not measured ones, and no prices. Frontier publishes a broadband facts label for each home internet plan with its monthly price and typical speeds.
