# Remove All Custom Zone Mappings from One Global Cluster

`DELETE /api/atlas/v2/groups/{groupId}/clusters/{clusterName}/globalWrites/customZoneMapping`

Removes all custom zone mappings for the specified global cluster. A custom zone mapping matches one ISO 3166-2 location code to a zone in your global cluster. Removing the custom zone mappings restores the default mapping. By default, MongoDB Cloud maps each location code to the closest geographical zone.
