AT&T availability: fiber, copper and Internet Air on the FCC map

Three networks under one name

The FCC data separate what one brand name hides. At 23,496,453 locations AT&T reports fiber to the premises, with advertised speeds up to 10 Gbps: the largest fiber footprint of any provider in the country, ahead of Verizon (9.5 million) and Frontier (6.9 million). At 23,271,883 it reports DSL over copper telephone lines, and at 37,394,690¹ licensed fixed wireless, the home internet service it sells as Internet Air. A location can appear in more than one of these counts.

Technology	Locations	At 100/20 Mbps or more	Fastest advertised download (Mbps)
Fiber	23,496,453	23,496,407	10,000
DSL (copper)	23,271,883	2,274,276	100
Licensed fixed wireless (incl. 5G home)	37,394,690	4,412,528	100

The difference matters for anyone choosing a provider. Fiber is reported at 100/20 Mbps or more almost everywhere AT&T has it (23,496,407 locations); DSL reaches that speed at only 2,274,276 of its locations, and fixed wireless at 4,412,528¹. When a site says "AT&T is available" at an address without saying which network, it is not saying much.

Where the footprint is

AT&T's wired network follows the territory of its former Bell telephone companies, across the South, the Midwest, Texas and California. Its largest states by locations reached are California (7,335,507), Texas (6,902,375) and Florida (5,420,080). In Texas it reports fiber at 41.3%¹ of all locations.

Outside that territory the picture changes. In New York, New Jersey and Virginia, for example, AT&T reports only fixed wireless: it reaches 50.9%¹ of New York's locations without a wire. The exceptions are the western states where AT&T now files Quantum Fiber, described below. In Alaska and Hawaii it lists almost no residential service.

State by state

The table lists every state where AT&T reports at least one location, with its technologies, its fiber locations and the change since the first National Broadband Map of June 30, 2022.

Change since 2022

Between June 2022 and June 2026, AT&T's reported footprint changed by +31,552,166 locations. Most of that growth is fixed wireless, which AT&T reports far more widely than it did in 2022; its fiber footprint grew by 11,131,731³. Part of any change between FCC releases comes from the FCC's own location list, which is updated with each release, and part from network changes: new fiber, copper retirements and the spread of fixed wireless.

Quantum Fiber moves into the AT&T filing

A large share of the fiber growth arrived in a single release. Between December 31, 2025 and June 30, 2026 AT&T's fiber count changed by +4,121,113, while CenturyLink's changed by −3,007,007⁴. Lumen, CenturyLink's parent, told the SEC it completed the sale of its consumer fiber business to AT&T on February 2, 2026, keeping its copper lines, and the June 2026 data show those fiber networks under AT&T's provider ID with the brand name Quantum Fiber.

That transfer explains why AT&T now reports fiber in western and northern states where it had no wired listings in June 2022: at 28.0% of Colorado's locations, 22.6% of Utah's, 18.8% of Minnesota's, 14.4% of Oregon's, 14.0% of Washington's and 13.8% of Arizona's. In its traditional territory the fiber shares are higher still: 41.3% of Texas, 40.9% of Georgia, 38.8% of Louisiana and 37.3%¹ of Florida. The CenturyLink page covers what Lumen kept.

Where AT&T is the only wired choice

At 483,552¹ locations, AT&T is the only wired provider offering 100/20 Mbps. Elsewhere it usually competes with a cable company, and in most of its fiber areas with fixed wireless from T-Mobile and Verizon as well.

Cities where AT&T reaches most locations

Among the 343 cities of 100,000 or more, AT&T's share of locations is highest in the cities below; its technology mix differs from city to city.

These are reported availability figures from AT&T's own FCC filings, as of June 30, 2026. They say nothing about prices or plans, which AT&T must show on its broadband facts labels, and they can be challenged on the FCC map where they are wrong.
