So from what I have seen Korean special sets don't have any code card, but main sets do. So from Scarlet and Violet I wouldn't expect code cards in Shiny Treasure ex (Paldean fates), 151, Night Wanderer (Shrouded Fable) or Terastal Festival ex (Prismatic Evolutions).
Korean pack does not have the code card. Is that something to worry?
