IVs to PID Applet
This applet allows you to find the PID of your Pokemon from its IVs and Nature. Remember that all legendary Pokemon and all Pokemon caught from Diamond and Pearl should have their PID created using Method 1, while other non-legendary Pokemon caught from Ruby, Sapphire, Emerald, Fire Red or Leaf Green can have their PID created using Method 2 or Method 3. See accompanying article for more information. You can also use this applet to check for the legality or otherwise of your unbred Pokemon.
