What the FCC Data Tells Us About AT&T Inc.

AT&T Inc. appears in the FCC Form 477 broadband deployment dataset with 5,264,043 individual filings spread across 21 states and territories. That volume of filings points to a multi-region 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, AT&T Inc. ranks #4 of 2,141 providers nationally. That is roughly 6,740x the median provider's 781 records, the FCC's midpoint value across all 2,141 reporting providers in this dataset. Put another way, AT&T Inc. 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. AT&T Inc.'s position in that sorted list is its rank (#4). The median is the midpoint value of that same sorted list, and the "roughly 6" comparison is simply AT&T Inc.'s record count divided by (or compared against) that midpoint.

The national rank above lines AT&T Inc. 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 California specifically, AT&T Inc. ranks #1 of 158 providers reporting in California by records filed there. We rank every provider that reports at least one record in California 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.

California is the largest single market for AT&T Inc. with 745,276 deployment records on file, followed by Texas at 727,304 records. Averaged across its footprint, the provider files roughly 250,669 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 AT&T Inc.'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.
