How do ID numbers work?

Question

You know how each Trainer gets their own unique ID number when they start a game? I was curious to find out how they work. How does the game know if your ID has already been taken? How the number is decided? How do in game trading peolpe get ID numbers? I am curious to know simply the process of ID numbers.

He only said ID in the question like 4 times, where died he say anything about a friend code?

Exactly; nothing. What made you think I was talking about Friend Codes? Oh yeah, you're banned. You can't answer me back...

Answer 1

Uh... actually, you CAN have the same ID as someone else. You can have from 1 to 65535 in ANY GAME. There's a slo a hidden ID, which can be determined (complex), that serves if the two IDs are the same. But the chances of ID number, Trainer name, and hidden ID matching are a 1 in 4,294,967,296 chance... the game will recognize them as the same person anyhow.
