I think in some comic books or cartoons, maybe a superhero like Superman could have his own zip code. It could be used for his secret hideout or something like that. But it really depends on the creator's imagination!
I can't think of any off the top of my head. Maybe some superheroes or fantasy characters could have their own zip codes in certain fictional universes.
I think Harry Potter could have his own zip code. The Harry Potter franchise is so vast and beloved that it might warrant such a unique thing. It could be used for special events or fan mail related to the series.
Well, in some fictional universes, superheroes like Superman might have their own zip code. It could be for special deliveries related to their heroic activities or for keeping their secret identities separate.
