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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Broadband adoption rates are highest in the Phoenix metropolitan area and parts of the Tucson metro, where many zip codes exceed 85–95%, reflecting dense urban infrastructure and higher household incomes. The northeastern portion of the state—encompassing much of the Navajo Nation and Apache County—displays starkly low broadband penetration, with numerous zip codes falling below 50%, highlighting persistent connectivity gaps in tribal and rural communities. A secondary band of lower adoption extends through parts of rural western and southeastern Arizona, though scattered zip codes near Flagstaff and Prescott maintain relatively strong broadband access.
