You can limit the physical location of a new resource with the Organization Policy Service resource locations constraint. You can use the location property of a resource to identify where it is deployed and maintained by the service. For data-containing resources of some Google Cloud services, this property also reflects the location where data is stored. This constraint allows you to define the allowed Google Cloud locations where the resources for supported services in your hierarchy can be created.
