Frequently Asked Questions
We use the Haversine formula, which calculates great-circle distances between ZIP code centroids with <1% error. This is the industry standard for logistics planning and is more than sufficient for delivery zone mapping and territory assignment. For exact driving distances, see our Driving Distance Calculator tool.
We use the US Census Bureau's ZIP Code Tabulation Areas (ZCTAs) from the 2020 Census, covering all 40,000+ US ZIP codes. Our database includes ZIP code, city, state, county, and geographic coordinates (latitude/longitude) for every location. Data is self-hosted and updated following each decennial Census.
Yes! Paid subscribers can upload a CSV file with up to 100 starting ZIP codes and their radii. The tool will process all locations and return a consolidated export with results for every starting point. Trial users can test batch processing with up to 10 ZIPs per upload.
All users can export to CSV format. Paid subscribers also get Excel (.xlsx) and JSON export options. Exports include all ZIP codes found, along with city, state, county, and distance from the center point.
You can search any radius from 1 to 500 miles. This covers everything from ultra-local delivery zones (5-10 miles) to multi-state regional territories (250+ miles). Unlike some free tools, we don't impose arbitrary radius caps.
Free tools typically limit you to one search at a time with ads and performance issues. Our tool offers unlimited batch processing for paid users, multiple export formats, saved search history, and blazing-fast results with no ads. If you need to process more than a handful of locations, we'll save you hours of manual work.
Not currently, but this is a web-based tool with batch processing capabilities that can handle hundreds of locations per upload. If you need programmatic access, please contact us to discuss your use case.
Yes, you can cancel your subscription at any time from your account dashboard. There are no cancellation fees or long-term contracts. Your access will continue until the end of your current billing period.
