# reverseLookup(coordinate, options) Converts a geographic coordinate to an address. ``` reverseLookup( coordinate: Coordinate, options?: GeocoderReverseLookupOptions, ): Promise; ``` ## Parameters `coordinate` The coordinate to convert to a human-readable address. For example, `new` ``Coordinate```(37.779268, -122.419248)`, which represents San Francisco City Hall. `options` An option that constrains reverse lookup results to a specific language. See [`GeocoderReverseLookupOptions`](/documentation/MapKitJS/GeocoderReverseLookupOptions). ## Return Value A promise that resolves with a [`GeocoderResponse`](/documentation/MapKitJS/GeocoderResponse) on success, or rejects with an `Error` on failure. ## Discussion Reverse geocoding converts geographic coordinates to the nearest human-readable address. The resolved [`GeocoderResponse`](/documentation/MapKitJS/GeocoderResponse) contains an array of places named [`results`](/documentation/MapKitJS/GeocoderResponse/results). Each place in [`results`](/documentation/MapKitJS/GeocoderResponse/results) has a [`coordinate`](/documentation/MapKitJS/Place/coordinate) property and a [`formattedAddress`](/documentation/MapKitJS/Place/formattedAddress) property. [`results`](/documentation/MapKitJS/GeocoderResponse/results) is an empty array if there isn’t a match. Pass an `AbortSignal` from an `AbortController` to the [`signal`](/documentation/MapKitJS/GeocoderReverseLookupOptions/signal) option to allow the controller to cancel a pending request. When the controller aborts, the promise it returns rejects with a `DOMException` whose `name` is `"AbortError"`. ## Topics [`interface GeocoderReverseLookupOptions`](/documentation/MapKitJS/GeocoderReverseLookupOptions) An option that constrains reverse lookup results to a specific language. --- Copyright © 2026 Apple Inc.
