The Requested Zip Codes card on the Delivery Rates page opens /admin/zipcodesnotfound (titled Requested zipcodes). It lists every state + zip code a website visitor searched for through the delivery-area checker (for example the See what days we deliver to your area button) for which no matching zip code entry existed.

Columns: State, Zipcode, Counts (how many times it was searched), Last Query and First Query. Filter by States or type in Search; the list loads more rows as you scroll. Use it to spot neighbourhoods worth adding to your delivery area.

In the current version this list is not split out per kitchen: the lookup that logs a "not found" zip code checks zip codes across all of your kitchens/locations, so it can include searches made on any of your storefronts, not just the one you have selected.
