- In Pokémon Black and White, it was the only regional Pokédex aside from that of Kanto to only contain Pokémon of one generation.
- The New Unova regional Pokédex contains 301 Pokémon, the largest amount so far.
- This is the only regional Pokédex where a starter Pokémon is not first in the listing and the only regional Pokédex to have a Pokémon numbered #000.
- In White, it is impossible to get a "seen" Pokédex entry for Vullaby or Mandibuzz without trading with another player, because they cannot be found in the wild in White, and no in-game Trainers use them. The same is true in Black for Rufflet, but not for its evolved form Braviary, as Cynthia and Miles of The Riches use one.
