US ZIP Code Distance
Estimate the straight-line distance between two US ZIP codes using a built-in state-capital and metro reference set.
About US ZIP Code Distance
Estimates the great-circle distance between the representative centroid points for the two state-capital or major-metro ZIPs you enter. Driving distance is usually 15–35% longer. ZIPs outside the built-in reference set are not resolved.
Formula
Haversine
distance = 2R·asin(√(sin²(Δlat/2) + cos(lat₁)·cos(lat₂)·sin²(Δlon/2)))

Assumptions and limits
- The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
- Reference set of US metro/capital ZIP centroids — approximate.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions
Why doesn't my small town's ZIP work?
This reference tool includes the 50 state capitals and major metro ZIPs only — not the full 40k+ ZIP database.
How accurate is this estimate?
Rates are approximate reference values. Local rates, exemptions and rules can differ, so treat the output as a planning figure only.
