Dollar Tree Doorables

So, I assume all the doorsbles from the Dollar tree don’t have codes or I’m just blind and very new to the the code world! One is pictured that is not mine and has a code in the black part and the 2nd picture is mine and has no code in the black part so is it safe to say that they don’t have codes? I’ve noticed too with a lot of other boxes I’ve gotten, they do not have codes. Is this because it’s the Just Play ones? Sorry I’m new to all this so I’m full of questions
