Hello there,
This information, (the RDS authorization number and the license key), can be found either in the confirmation email you received when you purchased the RDS licenses or in Microsoft Volume Licensing Service Center (after logging into your account).
- Sign in to VLSC.
- From the menu go to Licenses and click Relationship Summary
- Click at License ID number.
- At the next screen, you can find out:
a. At License Details field, the License Number
b. At Parent Program field, the Authorization number.
Hope this resolves your Query !!
