# Geocoders
{% hint style="info" icon="lightbulb" %}
Attach a geocoder to a market to enable address-to-coordinate conversion across that market's orders. Google and Bing are both supported.
{% endhint %}
## What is a geocoder?
A [geocoder](/core-api-reference/geocoders.md) converts a text address into geographic coordinates (for example, latitude `43.87913` and longitude `11.10094`). Attaching one to a market enables coordinate lookups for customers' shipping and billing addresses on that mar
ket's orders.
Coordinates can be used to place markers on a map, validate addresses, power location-based promotions, and other location-aware operations. **Google** and **Bing** geocoder integrations are currently supported.
