Zones are how USPS prices distance — zone 8 costs more than zone 2. Two ZIPs in, estimated zone out, right in your browser.
How zones map to distance

|---|---|
| 1–2 | local — up to 150 miles |
| 3 | 151–300 miles |
| 4 | 301–600 miles |
| 5 | 601–1,000 miles |
| 6 | 1,001–1,400 miles |
| 7 | 1,401–1,800 miles |
| 8 | 1,801+ miles |
Official zones come from USPS's origin-specific charts; this estimator uses ZIP-prefix centroids and great-circle distance, entirely in your browser.
