Got this info from someone else, just sharing the news as it worked for me.
"I found a SOLUTION after browsing on the technical support area of this forum.
If you have already registered your retail BETA code on the Ubisoft website, and received the confirmation email, but not received a key....
1. Log in to your Ubisoft account.
2. Go to the following page: https://tomclancy-thedivision.ubisof...ame/en-us/beta
It will load the page like usual and then should refresh after loading - showing your xbox/ps4 store download code."
