Derived statistics

Area codes are not Census geographies; statistics are estimated by aggregating ZCTA (ZIP) values for associated ZIPs.
ZIP↔area code associations are derived from NPA boundary polygons and ZCTA centroid points, and can be approximate.
Median age, mean commute, and household size are population-weighted; population density uses summed ZIP land area.

Area code overlays and service areas are primarily governed by NANPA; this page uses aggregated geographic overlays for orientation only.

Data accuracy & methodology

This report aggregates 2020–2024 ACS 5-year estimates and geographic overlays for orientation. Area code service areas can cross ZIP/state boundaries and change over time; verify official assignments with NANPA for critical use.
