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 / Independent Cities.
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.
