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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Northern Alabama's metropolitan zip codes around Huntsville and the Birmingham corridor display consistently higher broadband adoption rates, frequently exceeding 90%, while a pronounced band of lower connectivity (50–65%) stretches across the rural Black Belt region in the south-central part of the state. Coastal zip codes near Mobile show moderate-to-high broadband penetration, creating a visible contrast with the adjacent rural interior counties. The starkest digital divide appears between suburban zip codes ringing major cities—often reaching 95%+ adoption—and isolated rural zip codes in western and south-central Alabama where rates drop below 50%.
