How ZIP code estimates work
USPS ZIP codes are delivery routes, while Census ZIP Code Tabulation Areas (ZCTAs) are generalized areas for mapping and statistics. This page uses the matching Census ZCTA for its ZIP code estimate, so exact latitude and longitude lookups remain the better choice for property-level decisions.
