ZIP Code Zone Maps

USPS distribution zones visualized at three levels of precision — essential for logistics planning, sales territory definition, and geospatial analysis.

10 Regions 1-Digit Zones
1-Digit ZIP Code zone map showing 10 US postal regions Full size

Divides the U.S. into 10 broad postal regions (0–9). Northeast through West Coast. Ideal for national-level sales territory design and executive reporting.

Sub-Regions 2-Digit Zones
2-Digit ZIP Code zone map showing US postal sub-regions Full size

More granular sub-regional boundaries. Used for franchise territory planning, regional distribution strategy, and mid-level market segmentation.

Coverage Gap No-ZIP Areas
Map of US areas without ZIP Code coverage including wilderness and territories Full size

U.S. wilderness areas, national parks, and remote regions without ZIP Code assignment. Essential for data validation and address coverage QA.

Why ZIP Zone Maps Matter

  • Sales territories: 1-digit zones align naturally with regional VP assignments and quota modeling
  • Franchise boundaries: 2-digit and 3-digit prefixes create defensible, postal-system-aligned exclusion zones
  • Logistics & shipping: SCF-level zones match how USPS sorts and routes mail — use them to mirror carrier workflows
  • Coverage validation: The no-ZIP map prevents erroneous records for remote and unserviced areas

These maps are built from our ZIP Code Boundary Data — available in Shapefile, GeoJSON, KML, and more.
