About ZIP Code Distance

How distance is calculated and what it means

🧮 How It's Calculated

Distance is computed as the straight-line (as-the-crow-flies) distance between the geographic center points (latitude/longitude) of each ZIP code using the Haversine formula. This is the shortest possible distance between two points on Earth's surface, ignoring roads and terrain.

🚗 Driving vs. Straight-Line

The calculated distance is always the straight-line distance, not the driving distance. Actual driving distance is typically 20–40% longer due to roads, terrain, and routing. Use Google Maps or a routing API for exact travel distances.
