Licencování Microsoft produktů
Finding Your License and Authorization Numbers
Each donation request is assigned a license number and an authorization number (also called an agreement number) by Microsoft. These numbers are used to identify your request and might be needed to perform certain actions on the VLSC. It is useful to have these numbers available when you contact Microsoft customer service.
To find your license number and authorization numbers
Sign into the VLSC. Choose Licenses > Relationship Summary. This page shows information about all the Volume Licensing Agreements and Open Licenses that are associated with your account. Your license number for each request is listed under Licensing ID. Your authorization number for each request is listed under Parent Program on the line below the word OPEN (indicating these licenses are from the Open License program).
