I believe it's an Azure Subscription; under CSP, Global is the Azure public (i.e. not Government).
"MicrosoftAzure, which includes items for Microsoft Azure subscriptions (MS-AZR-0145P) and Azure plans"
So if you were to select that it would create an empty Azure subscription under the customer.
Your best plan of attack would be to reach out to your CSP and confirm etc, each CSP portal is different, at a guess the subscription would be 'Free' as there are no resources provisioned, but check with your CSP to make sure.
