Zone coverage reference

A companion reference to Manage zones, defining every field in a zone's Coverage Area editor, how polygon drawing works, the metadata field, and the Export Zone Data fields. For what a zone is and how the list works, start with Manage zones.

Note

This is a beta feature. Reach out to Nash if you'd like early access.

Values below describe what the zone detail form shows (labels, categories, and defaults). How a zone is matched to an order and how a bound optimization strategy acts on it are applied by Nash.

Coverage Area categories

The Coverage Area is an accordion of six category types. A zone can use any mix of them — each category holds its own list of values, and the Coverage column in the list summarizes what's set. A Clear all button empties every category at once. A search box above the accordion filters the categories and opens the ones that match what you type.

Category	How you add values	What it covers
Country	Type a name, or paste several separated by commas.	Whole countries.
State	Type a name, or paste several separated by commas.	States or provinces.
City	Type a name, or paste several separated by commas.	Named cities.
Zip Code	Type a value, or paste several separated by commas.	Individual postal / zip codes.
City and Zip Code	Type a value, or paste several separated by commas.	City-and-zip pairs, for zips that need a city to disambiguate.
Polygon	Draw the shape on the map (see below).	An arbitrary area you draw, not tied to a named boundary.

Adding values to the five text categories

For every category except Polygon, type into the category's input and submit to add one value, or paste a comma-separated list to add several at once. The placeholder reads Type name or comma separated values. Duplicate and empty entries are rejected as you add them.

Polygons

The Polygon category holds shapes you draw on a map rather than typed values. You can draw a polygon in two places:

• Inside a zone's Coverage Area editor, in the Polygon category.
• On the Coverage tab of the Zones page, using its Create mode — when you finish a shape there, a dialog lets you turn it into a new zone or add it to an existing one.

To draw, start a polygon and click on the map to add points, then close the shape to finish. Each finished shape is added to the zone's coverage as an area. Zones whose coverage can't be placed on the map (for example, an address that failed to geocode) are called out so you can fix them.

Metadata

Metadata is an optional JSON field on the zone detail form for storing extra key/value details about the zone. It takes a JSON object (the editor shows a { "key": "value" } placeholder) and is empty by default. It's a place to keep your own notes or attributes; Nash doesn't require it to define coverage.

Export Zone Data

The Export button on the Zones tab opens the Export Zone Data drawer. It builds a CSV of your zones from these fields:

Field	Options (default)	What it does
Store Location	Any store locations (all)	Limit the export to specific store locations. Leave empty to export all.
Specific Zones	Any zones (all)	Limit the export to specific zones. Leave empty to export all.
Sort By	Zone Name / Created Date / Last Updated (Zone Name)	How to order the exported rows.
Sort Order	Ascending / Descending (Ascending)	The direction for the chosen sort.
Only Deleted Zones	Off / On (Off)	When on, the export targets deactivated (deleted) zones rather than the active set. The exact set returned is applied by Nash.

Selecting Download CSV generates the file and opens it in a new tab.
