Each item has a number which is used to identify it in any game. The following list enumerates them according to the way that they are stored in the Generation V Nintendo DS games Pokémon Black and White and Black 2 and White 2.
- All items from Generation IV appear in Generation V, except for HM07, HM08, and the Generation IV Mail. Most of the Key Items are unobtainable.
- While the blank items in the middle of the list can be displayed, the "items" after the last item in the list cannot. The list can be viewed in-game if such item exists in the save file, but these items are unnamed and the game crashes when selected.
