Find out which fiber providers actually serve your address.

Every internet provider will tell you about their own coverage. None of them will tell you about anyone else's. WhereFiber puts the whole picture in one place, using public federal availability data.

Now covering every US address. Enter a street address and we show every provider that has reported service to the FCC at that location, across all 50 states, DC and the territories. No phone number, no sales call.

Why availability is the hard part

Choosing an internet plan sounds like comparing prices. In practice, the first question is far more basic: which providers can physically reach my home? Fiber networks were built street by street over decades. Two houses on the same road can have completely different options.

Provider websites only answer that question for themselves, and only after you hand over your address. Comparison is left to you, which is why so many people end up asking strangers on forums instead.

One address, every provider

Technology, not just brand

Fiber, cable, fixed wireless and satellite behave very differently. We label which is which.

Public data, shown plainly

Built on the FCC National Broadband Map, the federal record of reported service availability.

Fiber, cable, fixed wireless and satellite

"High speed internet" covers four quite different delivery methods. The one available at your address matters more than the brand printed on the router.

Technology How it reaches you What to expect
Fiber Glass optical line run to the building Symmetrical upload and download, low latency, unaffected by neighborhood congestion. Availability is the limiting factor.
Cable Coaxial line shared across a local node Strong download speeds, much slower upload. Widely available in urban and suburban areas.
Fixed wireless Cellular signal to a receiver at the property Quick to install with no line to the door. Performance depends on signal strength and local tower load.
Satellite Orbital link to a dish Reaches locations nothing else does. Higher latency, and usually the option of last resort.

General characteristics of each technology. Actual performance varies by provider, plan and location.

Major fiber networks in the United States

These are the largest residential fiber operators. Coverage is regional in every case, because none of them serves the whole country, and several overlap only in a handful of metros.

  • AT&T Fiber: large footprint across the South, Midwest and parts of the West.
  • Verizon Fios: concentrated in the Northeast and Mid-Atlantic.
  • Google Fiber: a smaller set of metros, expanding selectively.
  • Frontier Fiber: building out across its legacy telephone territory.
  • Quantum Fiber (CenturyLink): fiber service across much of the CenturyLink region.
  • Xfinity: primarily cable, with fiber in a growing number of areas.
  • Optimum, Cox, Spectrum and regional operators: mixed cable and fiber depending on the neighborhood.

Availability at any given address is what decides your options. We do not publish speeds or prices until we can tie them to verified data. Compare any two of them side by side, or read the guides if you want the plain version first.

How much choice Americans actually have

We ran the FCC's own filing block by block, across every US census block and every residential address in it, and asked one question: how many wired internet companies can reach this home? The answer is worse than the maps suggest, and it is published in full, with the method and both directions of bias stated.

Read the research: how much broadband choice do Americans have? Free to reproduce under CC BY 4.0, with a per-state figure and rank for all 52 states and territories.

We also publish who can actually get gigabit internet, ranked for every state and more than three thousand counties, which turns out to have almost nothing to do with how much choice a place has. Both studies, and the method behind them, are in WhereFiber research.

Internet providers by state

Each state page lists every operator reporting service there, how much of the state each one reaches, and where the state ranks for wired internet choice.

Internet providers by city

Coverage measured inside the city rather than averaged across the state, with each city ranked against every other place in its state. See all states and cities.

What we are building

WhereFiber is an independent site. We are not owned by an internet provider and we do not sell your details to one.

The address lookup is live and covers the whole country, built on the FCC National Broadband Map, alongside per-provider coverage pages and side-by-side comparisons. Some links on this site are affiliate links. See our affiliate disclosure for exactly how that works and what it does not change.
