Depending on the game and the nature of the match-up of digits, the player can receive a prize. This involves the generation of a random 5 digit number, which is compared with the player's Pokémon's original Trainer's ID numbers.

Once per week in Generation II and once per day in Generations III, IV, VI, VII, and VIII, the player may take part in the Pokémon Lottery Corner. Pokémon Lottery Corner Main article: Pokémon Lottery Corner If a Pokémon is transferred to Generation VII from a previous generation, its Trainer's ID number will remain 5 digits long. However, only the last six digits are used so the Trainer Card will display an ID No. The last six digits of the resulting number are what is displayed when the Trainer Card is viewed.įor example, consider a new save file in which the player's assigned Trainer ID and Secret ID are 0002, respectively. Rather, they are used to calculate the final ID number by using the following formula: ID final = ID trainer + (ID secret × 65536). A five-digit Trainer ID and a five-digit Secret ID are still generated but are not displayed on the Trainer Card directly. Pokémon transferred to Generation VII from the Virtual Console releases of Generations I and II are given a Secret ID of 00000.įrom Generation VII onward, the ID number is a six-digit number. Secret IDs from Pokémon obtained prior to Generation VII are five digits long those from Pokémon obtained in Generation VII are four digits long. If two different Trainers have the same 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. It also comes into play along with the normal ID number and the personality value in determining if a Pokémon is Shiny. Usually, this number cannot be viewed however, certain cheating devices can be used to view it, and there are also calculators to determine it. 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.

Once purified, the ID number will change to that of the Trainer who snagged it.įrom Generation III onward, there is a second, secret ID number, different from the visible one. It is also used for unpurified Shadow Pokémon. It will turn into the ID number of the Trainer who hatches the Pokémon. Also, for Pokémon not yet hatched from their Eggs, the ID ? is used. Sometimes, there are special ID numbers assigned to Pokémon if they come from a non-standard Pokémon game or are received as a prize. Special ID numbers Main article: List of notable ID numbers
