Frequently Asked Questions
ZIP code boundaries represent geographic outlines associated with postal delivery regions. These areas are designed for routing and mail processing—not for defining official city, county, or state borders. Administrative borders are defined by governments, while ZIP code boundaries are created for postal operations.
To understand how postal boundary systems work globally, see our Postal Boundaries product page.
The boundaries database includes multiple levels of administrative geography—from country down to subnational divisions—along with ZIP code boundaries at granular scales. These layers help analysts relate postal regions to administrative units, post office jurisdictions, sectional center facility regions, and Census-style geographic structures.
You can explore administrative hierarchy examples on our ZIP code boundaries product page.
An edge-matched polygon is a clean, non-overlapping shape whose borders align perfectly with neighboring shapes. In ZIP code boundary datasets, edge-matching ensures that each ZIP polygon connects seamlessly to adjacent regions—avoiding gaps, slivers, or overlaps that can distort coverage maps.
Our boundaries are fully edge-matched and optimized for GIS workflows. Learn more on the Postal Boundaries product page.
The best geographic level depends on your use case:
- Statistical analysis: ZIP Code Tabulation Areas (ZCTAs) or larger administrative levels
- Routing or logistics: Five-digit ZIP code boundaries or delivery-route-oriented postal geographies
- Local analysis: The smallest available ZIP code geography
- Infrastructure, planning, or demographic context: Higher-level administrative divisions
If you need population-based or demographic alignment, see our Population Data product.
Yes. Our ZIP code boundaries and administrative layers are provided in industry-standard formats (GeoJSON, Shapefile, GeoPackage), ensuring seamless integration with ArcGIS, QGIS, and all major GIS platforms. Users can visualize postal regions, overlay Census datasets, and connect ZIP polygons to street and address datasets.
