US Area Code Statistics

Average area code utilization by state. New Jersey leads with MT at 94.2% average utilization across 1 codes. 9 of 51 states/DC have average utilization above 80%, indicating potential future relief planning needs.

Across all 235 area codes, the total population covered is 444.4M. The average median household income is $77,892, with an average poverty rate of 12.8%and unemployment rate of 5.1%. Approximately 32.9% of residents hold a bachelor's degree or higher. CA leads in population coverage with 42.8M residents.

Number of area codes per million people. DC leads with 1.49 codes per million, followed by WY (1.45) and VT (1.33). States with denser populations require more area codes to serve their telecommunications needs. The total of 235 codes are distributed across 51 states and DC.

Across 235 area codes in 51 states, median household income ranges from $24,307 to $159,674, while population density spans three orders of magnitude. States with more area codes — like California (41), Texas (29), and New York (23) — tend to cluster in the high-density, higher-income quadrant, reflecting the concentration of telecom demand in major metro areas. Meanwhile, low-code-count states are scattered across rural, lower-density regions with moderate incomes. The pattern reveals that area code allocation closely tracks both population density and economic output: denser, wealthier areas require more area codes to serve their larger number of prefixes.
