Can I make live sandbox keys that will only activate when the game releases?

Hello,

I am doing a contest where if someone makes social media content and submits it to me I will give them a free key on release, I was wondering if there was a way to give them the key now and have it only unlock on public release date?

Thank you

Hello there,

If access keys are given out of a game that is unreleased and the account it is added to is NOT apart of your organization or added to a player group, then the game will be unavailable to the end user.
