I need to clarify if they're asking about online access, DLC codes, or something else. If they found an access code, they might need instructions on how to use it. Since Street Fighter IV doesn't use such codes, the advice would be to check for validity, confirm if it's for another game, or contact support if it's related to DLC. Also, mention that for Street Fighter V and later, the Store is used, but that's a different game.
