The report is actually based on the Census Block data from the NTIA. This is more specific than Zip codes. The broadband search is based on zip for ease of use.
The providers shown on a zip search are providers that reported having at least some coverage in that zip (translated from census blocks). It doesn't mean everyone in the zip has access to all those providers.
