The most common reason for missing country or state (if applicable) data is that your billing system does not contain country data for customers. ChartMogul only pulls metadata such as the address and region from the billing object when the customer is first created. This means that if the customer signs up without adding a credit card or billing address, it would not populate when they are imported into ChartMogul and would not update if this information is added at a later time.
The customers location can be seen in their customer profile:
If you want to take full advantage of ChartMogul's Maps feature you need to add the country and state data to the customers in your billing system.
If this is not available in your billing system for any reason, you can add it manually via the user interface by clicking on "UPDATE CUSTOMER DETAILS" then entering the information.
Another option to add this data in bulk would be to use the Import API.
