The Entitlement ID is the key to initial license activation as well as for re-ordering additional software options.
The Entitlement ID consists of 25 alphanumeric characters that are separated by dashes; for example:
Entitlement ID: 9A9A9-A9A9A-9A9A9-A9A9A-9A9A9
You can find the Entitlement ID on the Invoice and on the delivery note of the purchased software product. You can also find it on a separate Entitlement Certificate on paper or in digital form (such as an HTML document).
The Entitlement ID for a software product never changes; therefore, you should keep these documents in a secure location.
