I find it interesting that we use them to represent areas while they were only intended to represent routes... And this relates to why there are some ZIP codes that are in multiple states. | |||||||||||||||||||||||

Physical routes tend to end in contiguous areas. It's rather difficult to teleport a mail delivery truck. | |||||||||||||||||||||||

ZIP codes are the route a mail truck takes to deliver mail. That mail truck begins and ends it's route at a specific Post Office. The +4 portion of the ZIP code denotes where along the route something is such that mail can be sorted in the order it will be encountered along the route. So a ZIP code is an area. A ZIP code is often used incorrectly to apply other demographic information such as race or income, those are generalizations and not necessarily 100% accurate. | |||||||||||||||||||||||
