[Teen Titans Go] What Earth is this taking place on?

I'm aware that there are multiple Earths (some may even say infinite), but the databases don't mention the Earth this version of Jump City is in. Do we have any idea?

Nothing concrete has been mentioned.  The Teen Titans Go! team are clearly aware that there's an alternate-Earth with better, more serious versions of them, as well as another alternate-Earth where they can meet their voice actors, writers, and production crew.  All we know is that it's a younger, sillier version of the original Teen Titans tv universe, which they're aware of because of Control Freak and 4th wall breaks.
