    Broadband Map's availability estimates are based on the census boundaries of California. Speed metrics capture internet providers' maximum advertised speeds. Both may be overoptimistic.

    Data Sourcing

    Broadband Map's listings of internet providers in California rely primarily on the May 2026 release from the FCC's Broadband Data Collection program (representing California ISPs' availability as of December 2025).
