What the FCC Data Tells Us About Comcast Corporation

Comcast Corporation appears in the FCC Form 477 broadband deployment dataset with 1,694,032 individual filings spread across 40 states and territories. That volume of filings points to a nationwide operator, each record represents a distinct census-block-and-technology combination the provider has reported serving, so the raw count reflects both geographic reach and the number of technology tiers the company deploys (for example, fiber and DSL in the same block count as two records).

By total records filed, Comcast Corporation ranks #8 of 2,141 providers nationally. That is roughly 2,169x the median provider's 781 records, the FCC's midpoint value across all 2,141 reporting providers in this dataset. Put another way, Comcast Corporation sits at the top 1% by filing volume among every provider in the Form 477 dataset.

How we calculate this rank

We sort every provider with a Form 477 filing (2,141 in total) by total records, from highest to lowest. Comcast Corporation's position in that sorted list is its rank (#8). The median is the midpoint value of that same sorted list, and the "roughly 2" comparison is simply Comcast Corporation's record count divided by (or compared against) that midpoint.

The national rank above lines Comcast Corporation up against every provider in the dataset, from single-block filers to nationwide carriers, which can bury a strong regional player. A narrower, arguably more useful cut: within Pennsylvania specifically, Comcast Corporation ranks #5 of 75 providers reporting in Pennsylvania by records filed there. We rank every provider that reports at least one record in Pennsylvania against every other provider reporting in that same state, so the comparison is apples-to-apples with local competitors rather than the entire nationwide field.

Pennsylvania is the largest single market for Comcast Corporation with 176,756 deployment records on file, followed by Illinois at 165,762 records. Averaged across its footprint, the provider files roughly 42,351 records per state, a useful yardstick for comparing how deeply it has penetrated each territory versus competitors listed on the same state pages.

Keep in mind Form 477 counts filings, not subscribers or homes passed. A high record count means the provider has told the FCC it is capable of serving many census blocks; it does not guarantee active service at any specific street address, nor does it reflect actual subscriber numbers. Use this page alongside the state breakdown below to see where Comcast Corporation's reported footprint is densest, and cross-reference with the technology mix on each state page to understand what speeds and delivery methods are on file for each market.
