I'm not sure. Whats a centroid point. I think we'd want to do the "contained within the radius" one. but the thing is I not looking to use any visual maps. I just need the zip codes and then figure out how to do the radius thing for the search function. Where can I get the geocoded database of zipcodes. Does it cost any thing?
Thank you very much for your help.
