The county layer
Every county. State by state.
Every county with an RCLX market page, grouped by state, with the county value from the FCC Broadband Data Collection or from published service-area pages. Each county links to its market pages.
County layer built May 11, 2026 · Federal source: FCC BDC J25 (29 April 2026)
Two sources, one filter
Where each county comes from.
A county value says the footprint reaches the county. It can’t tell you which street.
Filed with the FCC
Most counties carry a share from the FCC Broadband Data Collection: the part of the county’s homes filed as fiber-served by the fiber networks this layer tracks. A county figure, not a street.
Listed on a service-area page
Where the federal file had nothing yet, the county comes from a network’s own published service-area page. Those carry a status instead of a number: live or building, or announced.
Only where a market page exists
A county shows up here only when one of our market pages sits in it. It’s the same filter that decides which city pages exist, applied once.

Read it right
A county isn’t a street.
A county can file a high fiber share and still hold whole towns with no plant. A county listed as announced can have crews in the ground next month. That’s why every market page carries its own numbers, and why we run live address checks before we quote a sellable rate.
The measured side lives on the serviceability table. How both layers get built is on the methodology page.
Providers report their own coverage to the FCC and those reports can be challenged. Advertised speeds are ceilings, not what a given house gets. Nothing on this page is a promise of territory, earnings, or service at any specific address.
