I have two sets of licenses from years ago. How can I find which ones have been consumed? And how many times? Also, how can I find from which vendor they were purchased?

I have two sets of Acrobat Pro keys, and a set of Creative Cloud licenses which includes Acrobat Pro. How can I find out which licenses are still available to use? On the Creative Cloud site, that is simple enough, but is there a site i can check for the licenses? For one set of keys, i am given a reference link to https://adobe.subscribenet.com/ where I can go to download the software, but it doesn't explain how many licenses I have and if they are used or not. Any help is appreciated.
