Independent guide — not the government, not a Lifeline provider

Updated July 2026 · FCC data as of December 31, 2025

U.S. Broadband Coverage Map

The U.S. broadband coverage map below compares FCC Broadband Data Collection signals by state and county, including wired 100/20 coverage, fiber availability, mobile 5G 35/3 area coverage, provider counts, and a broadband weakness score. Updated July 2026 using the FCC summary release from June 2026, it is built for people who need a clearer companion to the official address-level map.

National FCC broadband coverage

State and county coverage map

Weighted score using wired 100/20 gaps, fiber gaps, mobile 5G gaps, terrestrial fixed coverage, and provider counts. The map renders the 50 states and D.C.; the downloadable CSV includes additional FCC county-equivalent rows where available.

What this map shows

Broadband coverage by state and county, explained in plain English

This broadband coverage map summarizes the most useful FCC broadband availability signals for comparing places, not individual addresses. You can switch between state and county views, then compare wired 100/20 coverage, fiber 100/20 coverage, mobile 5G 35/3 area coverage, provider counts, and a weighted weakness score.

The map is meant to answer questions like: which counties still appear weak for modern wired broadband, where fiber availability is thin, where mobile broadband coverage is less robust, and which states deserve closer review before a resident assumes competitive home internet is easy to buy. It does not replace the official FCC address lookup, because a county can look strong overall while a specific road, apartment building, tribal area, or rural household still has limited service.

The CSV download includes county-equivalent rows beyond the 50 states and D.C. where they appear in the FCC summary data. The interactive map uses the U.S. state and county geometries available in the site map library, so Puerto Rico and other territory rows should be treated as downloadable data rather than map shapes in this first release.

Coverage weakness analysis

Where broadband coverage looks weakest

The weakness score is a directional ranking, not a legal service classification. It weights wired 100/20 gaps most heavily because wired home broadband is still the strongest proxy for durable fixed internet access. It also includes fiber gaps, 5G 35/3 area gaps, terrestrial fixed broadband gaps, and lower provider counts.

This makes the page useful for journalists, grant writers, libraries, digital inclusion teams, benefits navigators, and local officials who need a fast way to identify places that deserve deeper broadband review. For address-level decisions, use the official FCC map after narrowing the area here.

How to use it

How to check a state, county, or address

Start with the map if you want regional context. Choose "States" to compare broad patterns, then switch to "Counties" and filter by state when you need a more local view. The highest-attention list updates with the selected metric, so a county can surface for weak fiber even if it looks stronger on mobile coverage.

If you are checking whether internet service is available at a specific address, use this page as the first layer and then verify the exact location with the FCC National Broadband Map. Provider availability can change at the parcel, building, road, or unit level, especially in rural and newly built areas.

If your real question is affordability, coverage is only half of the problem. A household can live in a county with several broadband providers and still struggle to pay for service. That is why this page links broadband coverage context to Lifeline eligibility without treating the broadband data as a Lifeline provider service-area list.

Frequently asked questions

Broadband map questions

What is the best broadband coverage map?

For exact address checks, the official FCC National Broadband Map is the source to use. This Cliq Mobile map is designed as a faster companion for state and county comparisons, with plain-language broadband weakness scores and downloadable county data.

How do I check internet coverage by address?

Use this page to compare a state or county first, then open the FCC National Broadband Map and enter the street address. County-level coverage is useful for context, but address-level availability can change block by block.

Does broadband coverage mean service is available at my address?

No. Broadband coverage data is reported at geographic summary levels and can show likely availability, but it is not a service guarantee for a specific home, apartment, farm, or business. Always confirm with the provider and the FCC address lookup.

What areas have the weakest broadband coverage?

Rural, remote, mountain, tribal, and island communities tend to surface more often when the map weights wired 100/20 gaps, fiber gaps, mobile 5G 35/3 gaps, terrestrial fixed coverage, and provider counts. The table on this page lists the highest-weakness counties in the mapped U.S. states and D.C.

Can this show Lifeline internet providers?

Not by itself. FCC broadband summaries are not the same as Lifeline Eligible Telecommunications Carrier service-area records. This map is best for broadband coverage context; Lifeline eligibility and low-cost internet options should be checked separately.

Low-cost internet help

Think affordability is the real barrier?

Coverage data can show whether networks are reported nearby, but it does not show whether a household can afford service. Lifeline may reduce the cost of phone, internet, or bundled service for eligible households.

Data sources and methodology

How this broadband coverage map was built

The map uses FCC Broadband Data Collection summary data released in June 2026, with coverage reported as of December 31, 2025. The state and county views summarize residential fixed broadband availability, wired and fiber availability at 100 Mbps down and 20 Mbps up, mobile broadband area coverage, and fixed/mobile provider counts.

The weakness score is calculated from six signals: wired 100/20 coverage gap, fiber 100/20 coverage gap, mobile 5G 35/3 area coverage gap, terrestrial fixed 100/20 gap, fixed provider-count scarcity, and mobile provider-count scarcity. The score is designed to rank places for further review; it is not an official FCC designation and should not be used as the only basis for funding, legal, engineering, or eligibility decisions.

For exact addresses, cite and use the official FCC National Broadband Map. For California-specific deployment, adoption, and priority-unserved context, use the California Broadband Map. For affordability and participation context, compare this map with Cliq Mobile's State of Lifeline report.

Average fiber 100/20 coverage across 50-state and D.C. county rows in this dataset is 56.7%. The figure is an unweighted county average for quick comparison, not a household- weighted national availability estimate.
