If your account went into any type of 'cold storage' back when that system existed (it might still exist too, I don't know as mods don't really deal with that) when you reactivated the account it would get a new ID I believe. Might also have been some weird changes when the GameSpot/GameFAQs merger happened too.
Changing your username does not change your user ID number.
