ZIP Codes - Key Concepts

1. ZIP Codes are categories for grouping mailing addresses and are not exact geographic regions.
2. The centroid of a ZIP Code may be in one County and the associated city/town in another.
3. In rural areas, a single ZIP Code may be used for cities and towns in several different Counties.
4. ZIP Code "areas" can overlap, be subsets of each other, or be artificial constructs with no geographic area.
5. ZIP Codes are only loosely tied to cities.

¹ Keeping the above key concepts in mind, what we informally refer to as the "center" of a ZIP Code is most often actually the centroid of a polygon.
