In the Pokémon games, an '''identifier''' (also '''index number''' or '''ID number''') is a number used within the game's code to identify pieces of data. Pokémon, items, locations, moves, and abilities all have unique identifiers; in each game, no two Pokémon have the same identifier. Pieces of data in different categories, however, may share identifiers -- a Pokemon and an item may use the same identifier, for instance. Identifiers may be likened to character codes in [[Wikipedia:Character encoding|computer text]].
If the size of data is one byte, this usually means that the data can be represented by 256 index numbers (16^2 or 2^8). If the size is two bytes this would mean the data could be represented by 65536 index numbers (16^4 or 2^16) and so on.
An identifier is the value in a memory address, or the two digit number in the second and third digits of a GameShark or Xploder code/first two digits in a Game Boy Game Genie code (for example, in 01xx59D0, 010259D0 means the index number is 02).
In the [[bp:Generation I|first generation]] core games (Red/Green/Blue/Yellow versions), the Pokémon's identifiers did not match the Pokédex numbers assigned to them (e.g. Pokédex number 1 is assigned to Bulbasaur, while identifier 1 is assigned to Rhydon).
This is believed to be due to Pokémon being assigned to these numbers during game development (confirmed by a few Pokémon having them in the official Satoshi Tajiri: The Man Who Created Pokémon manga namely Diglett and Venonat). A few placeholder or unused entries remained in the final game, known as the [[MissingNo.]], which there are 39 of.
The identifier, not the Pokédex number, must be used for [[cheating device|cheat codes]] and in-game glitches like the [[Old Man Trick]] or [[Ditto Trick]].
