My wild guess is these will be codes for guaranteed beta access for all of the advanced missions upcoming.
Can't be one time beta access because besides this is fun, it is too much trouble for that specially when there are free giveaways that takes a second to get a key. Can't be an alpha neither because every video says "enlist for beta"

Says that codes already been claimed.
The fragments codes that you get in game are not the same codes people is talking about.
on game when you kill enemies or do missions you randomly get fragments of a lockbox codes key or if you are lucky you get the full key code those are ONLY for lockboxes.
The codes that people are talking about are 6 letter alphanumerical codes that are scattered all over, on game videos, game pages, disguised under the alien language, on e-mails from defiance and even on the Source Code of defiance pages.
And those codes you redeem them here
The only guide you have to look for them are that the codes are in Defiance related things.
I hope this helps.
