This is for Adobe Business Catalyst - Adobe's CMS Website system. It does not have software you install or a card id.
Do you mean Creative Cloud? You may want to go to the adobe Creative cloud site and ask for support there.
As Liam mentioned you are in Business Catalyst forum which doesn't require and key/code/serial to use.
I believe you are referring to Creative Cloud subscription. If so you'll want to reach out to our licensing team.
Help and support for this can be found here - Redemption Code Help
It's all good
