Can a zone be a postcode list?

Yes. Postcode boundaries are boundaries like any other: search them, fetch their polygons, and union them into one zone.

How fresh is the data?

Boundaries come from OpenStreetMap and are cached the first time anyone asks. Each response says when the geometry was fetched.

Delivery & service zones

Delivery and service zones from real boundaries

Most delivery zones are a list of places: these cities, those postcodes, not that district. Draw them from the official boundaries instead of by hand, and check every order against the same polygons.

The problem

Hand-drawn zones drift from the real city limits, so customers on the edge get the wrong answer.
Ops teams describe zones in words (“all of Brooklyn except Red Hook”) that someone then has to redraw.
Every new market means another afternoon in a map editor.

With Geocode AI

Pick the places
Search boundaries by name and keep the ids, or describe the zone in a sentence and let Areas compose it.
Store the polygon
Fetch GeoJSON at the detail you need and keep it in your database, or keep calling us: cached boundaries are fast.
Check each order
Send up to thousands of points in one contains call and get a yes/no per point, or reverse-geocode a point to every boundary around it.

The calls you'll make

Copy-paste examples. Search is free; the rest needs a free API key.
