Ah so I just checked what you're talking about and Fanatical just means that it activates in your region and it's not locked to US. You can click the "View All" button next to the "Activates in United States" and click each individual region that you're interested in to see if it's blocked (helpful if you're giving to a friend since going through them all to find region restrictions for SG is tiresome). There's also posts similar like this in the discussion thread - https://www.steamgifts.com/discussion/Ddetq/fanatical-build-your-own-enigma-bundle-2 - where the main post will get the subID and region restrictions added in after there are reports from purchasers. I think this one doesn't have one just because all the keys are already ROW.
