Those are called Outermost Regions (OMRs), and there are 9 of them, for instance french guiana.
Due to their remoteness, they are exempt to some EU laws. But they are part of the European Union.
Then there are some regions which are part of the European Economic Area (EEA), but not the EU, like Norway or Switzerland.
And several further distinctions and special cases afaik.
EEA, countries in Europe but not in EU, Schengen and so on I'm familiar with, but it's the first time I heard about Outermost Regions. Thanks for explaining!
