New Zip Code Union (Merge) Program

We've published an new version of the popular 2000 ZCTA zip code boundary (click here) map that allows the merging of multiple zip code areas into one large area. This map (2000 ZCTA Zip Code Union Demo) can take a list of zip codes, clicks on the map or keying in zip codes one at a time to construct this merged (union of polygons) boundary.
