Activating your order is required for specific types of Oracle Cloud subscriptions. If you order your Oracle Cloud subscription by contacting Oracle Sales and it is not an order for Oracle Infrastructure as a Service (Oracle IaaS) and Oracle Platform as a Service (Oracle PaaS) services with universal credits, then you might need to activate the service, using a link in the activation email you receive when your order is processed.
You don't need to activate your order if you have ordered IaaS or PaaS services with Universal Credits from the Oracle Cloud website.
Oracle Cloud processes the request or order, sets up the service, and sends an email to the account administrator when the service is ready to be activated. The account administrator then uses the My Account application to activate the service.
