Learn how to find an address or place using a search box and the geocoding service .
Geocoding is the process of converting address or place text into a location . The Geocoding service can search for an address or a place and perform reverse geocoding . Use the Esri Leaflet Geocoder module to access the Geocoding service and perform interactive searches.
In this tutorial, you use the Esri Leaflet Geocoder Geosearch control to search for addresses and places.
You need an ArcGIS account to access the developer dashboard and create an API key .
To get started, either complete the Display a map tutorial or use this pen . To access location services , you need an API key or OAuth 2.0 access token .
Go to your dashboard to get an API key. The API key must be scoped to access the services used in this tutorial.
In CodePen , update apiKey to use your key.

Add the following code to add the Esri Leaflet Geocoder control to the map:
Change the basemap layer to Navigation and set the location to Sydney. Create the geocoder and add it to the map. Create a group for the marker. Use a handler to add the result as a marker. Show more lines

In CodePen , run your code to display the map.
Click on the geocoder control and enter an address or place such as "Starbucks". When you select a result, the map will zoom to its location.
