An in-game trade is a trade made with NPCs in the core series and spin-offPokémon games. The process uses the same trading sequence as player trades and is usually done for Pokémon that are difficult or impossible to obtain through other means, or for Pokémon unavailable at that point of the game. In later games, the traded Pokémon often has special moves, like Egg Moves.

All Trainer ID numbers and IVs are random in the Generation I games. The original Trainer always uses the hardcoded text string 0x5D, which is displayed as TRAINER (Japanese: トレーナーTrainer) in the game's language. In Western language versions of the handheld games and Pokémon Stadium, this string is displayed in ALLCAPS ("TRAINER" in English), whereas in Pokémon Stadium 2 it is displayed in title case ("Trainer" in English).
The held item column refers to the item the Pokémon will be holding if it is traded to a Generation II game. With the exception of Pokémon that evolve during that trade and Krabby in Japanese Blue, they have the same item a wild Pokémon of the same species would have if it were traded to a Generation II game; Pokémon that evolve during the trade have the item their evolved form would have, while Krabby has TM13 (Snore) instead of TM33 (Reflect).
In the English language version of Pokémon Diamond and Pearl, Kazza, Charap, and Gaspar are functionally Japanese in origin. While this has no effect in the Generation IV games (since their species do not have foreign Pokédex entries in the Generation IV games), it becomes noticeable when sent to later generations. These Pokémon have the correct language of origin if obtained in any other game language or Pokémon Platinum.
In Nimbasa City, after returning the Dropped Item to the owner and calling them 51 times, Yancy or Curtis (depending on the player's gender), will trade the player a different Pokémon each day, in this order. Each Pokémon has its Hidden Ability and can be either male or female.
↑This Pokémon will evolve due to being traded, but Pokédex data for the unevolved Pokémon will be registered before it evolves.
Underleveled Pokémon
Since the Pokémon received in an in-game trade is the same level as the one traded prior to Generation V, it is sometimes possible to receive a Pokémon at a lower level than normally possible.
Similarly, the old man who trades the player Jynx for Poliwhirl in Cerulean City claims that Poliwhirl "went and evolved". Poliwhirl does not evolve by trade in the Generation I games but rather through the use of a Water Stone. In the context of the Japanese Pokémon Blue, the old man trades away Haunter for Machoke, both of which evolve by trade.
In Pokémon Crystal, even if the player has their Haunter hold an Everstone and trades it for Chris's Xatu "Paul", Chris will still comment that it evolved into Gengar.
