# geo\_country\_code By default, Transparent Edge geolocates all requests that pass through our systems by sending a header to the origin with the country code from which the request was made. This is the **Geo\_Country\_Code** header. ``` geo_country_code: ES ``` If the system was unable to locate the user's IP, it sends the Unknown string in the header. Thanks to this feature, there are a great many things we can do based on the location of the end user, such as: * Block/permit content from certain countries. * Send requests to different origins based on the geographical location of the end user. * Serve special content by country. * Rewrite headers based on the country the request came from. * Custom rules based on that header. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
