ZIP code coverage map
Paste the ZIP codes you cover. See the shape they make, the gaps in the middle, and the ones that turn out to be nowhere near the rest.
The outline appears here. Nothing is uploaded or stored.
What the shape tells you
- A hole in the middle
- A ZIP somebody forgot, usually the one the office sits in. It is invisible in a list and obvious the moment the area is drawn.
- An island on its own
- One ZIP an hour from everything else, normally left over from a customer who moved or a rep who used to live there. It quietly sets the drive time you promise everybody.
- A long thin strip
- A corridor built by following a motorway. Fine, as long as the person routing jobs knows the far end is ninety minutes away.
Why ZIP codes are not really areas
A ZIP code is a set of delivery routes, not a region with a boundary. The shapes here are Census ZIP Code Tabulation Areas, which approximate those routes closely enough to draw and to reason about, and which is what almost every tool that shows you a ZIP map is using underneath.
It is worth knowing because the edges are approximate. For deciding who covers a street, an address resolved to a point inside a boundary is a firmer answer than a ZIP match, and that is what the address lookup does.
Turn a list into something you can change
A drawing is a start. The useful version is a territory you can adjust, assign to a team, and ask questions of, with every answer explaining itself.
