Trainer ID number: Difference between revisions

[[File:OT ID.png|thumb|This {{p|Tepig}}'s Trainer's ID number is '''23202'''.]]

A [[Pokémon Trainer]]'s '''ID number''' is a five-digit number that is assigned to a Trainer when they begin their Pokémon journey. It is used, in conjunction with the [[Original Trainer|Trainer's name]] and gender, to identify whether the Pokémon is an [[outsider Pokémon]] by the {{pkmn|games}}. The highest possible ID number in any game is [[wikipedia:65535|65535]].

From [[Generation III]] onward, there is a second, secret ID number, different from the visible one. This number exists purely to make sure that even if two Trainers share the exact same name and gender and the exact same Trainer ID number, the game will still recognize their Pokémon as coming from different Trainers. Usually, this number cannot be viewed; however, certain [[Cheating|cheating devices]] can be used to view it. It also comes into play along with the normal ID number and the [[personality value]] in determining if a Pokémon is {{Shiny}}. If two different Trainers have the same [[Original Trainer|Trainer name]], identical ID numbers and identical hidden ID numbers (a 1 in 4,294,967,296 chance if the names do not differ), the game will recognize the two Trainers as the same, so the Pokémon are not considered to be [[outsider Pokémon]].

From [[Generation II]] through [[Generation IV]], the player may take part in the Pokémon Lottery Corner every day (every week in Generation II). This involves the generation of a random 5 digit number, which is compared with the player's Pokémon's [[original Trainer]]'s ID numbers. Depending on the game and the nature of the match-up of digits, the player can receive a prize. This feature was not included in the [[Generation V]] games.
