The Wrestler ID is the internal ID number of the wrestler in the WWE 2k series of Games. It is a numeric identifier uniquely assigned to each wrestler slot and is used for the ch*.pac number, in .pofo, .moveset, .team_info files and more. It is also sometimes referred to as PACH Number, PACH Slot number, PACH ID, PAC ID, PAC Number, PAC Slot Number, SlotID (as seen in CCT) or similar.
Valid Wrestler IDs
Valid Wrestler IDs typically run from 0-999. Wrestler IDs 0-99 are usually reserved for Created Superstars, while Wrestler IDs for in-game wrestlers and mods typically range from 100-999. Note that which IDs from that range actually work is different from game to game.
Wrestler IDs are most prominently needed to install mods. The Wrestler ID is generally used as the XXX in chXXXYZ.pac Wrestler Models/Texture Archive, *XXX*.pofo Wrestler Information and *XXX*.moveset Entrance and Moveset file names and their contents as well as contents of the .team_info files to link them all together.
