% of Households with Broadband Internet, by Zip Code (ZCTA5) — Montana

NOTE: Gray indicates insufficient data or a suppressed estimate.

Broadband adoption across Montana's zip codes generally ranges from 70% to 95%, with notable pockets of low connectivity (below 50%) concentrated in several reservation areas, including portions of the Crow, Northern Cheyenne, and Fort Peck reservations in the eastern part of the state. Western Montana, particularly zip codes around the Flathead Valley, Missoula, and Bozeman corridors, tends to display higher broadband penetration rates in the 85–95% range, reflecting denser population centers with more robust infrastructure. Scattered rural zip codes throughout central and eastern Montana show considerable variability, with some areas reaching near-100% adoption adjacent to others falling below 60%, highlighting the uneven distribution of broadband access even within the same counties.
