FCC Broadband Data Collection coverage is filed at the location level by every facilities-based provider and rolled up to ZIP, county, and state aggregates roughly every six months. A Cox Communications report inside a Arizona ZIP code means at least one address inside the ZIP qualifies for service; it does not guarantee every home in the ZIP can subscribe at the advertised peak tier. For a definitive address-level check, use the FCC's public lookup or call the carrier directly.
