Broadband Map's availability estimates are based on the census boundaries of Columbia. Speed metrics capture internet providers' maximum advertised speeds. Both may be overoptimistic.
Broadband Map's listings of internet providers in Columbia rely primarily on the May 2026 release from the FCC's Broadband Data Collection program (representing Columbia ISPs' availability as of December 2025).
