How this list is calculated
Each ZIP code is represented by a single centroid point, and distance is measured great-circle from the centroid of 98237 to each of the others. Two consequences worth knowing about:
- Large rural ZIPs distort the picture. A ZIP covering 400 square miles has a centroid that may be 15 miles from its own nearest edge, so a code listed as 30 miles away can begin much closer.
- These are not driving distances. A river, a bay, or a mountain range makes a 12-mile straight line into a 40-minute drive. For service-area planning, use this as a first cut and check the routes.
If you need this programmatically — for a store locator, a delivery zone, or a territory map — the radius endpoint returns the same data as JSON, with an arbitrary radius and optional state filtering.
