I worked somewhere that purchased ZIP code polygons from somewhere at one point, pretty sure it was way way cheaper than this. Idk if there was a difference in quality.

ZIP codes aren’t even guaranteed to be polygons. Most data sets use the census bureau’s ZIP code tabulation area.

		There were multiple polygons per ZIP code. Or do you mean it can have round boundaries?
