What are Monster High doll codes?

Answer 1

I don't really know myself. I think they are just codes for the lockers. The lockers are online if you don't know. They are under registration and then the locker bit I can't remember what it is called. When you get on it, if you look at the side of the computer screen there is a long list of names (names of the Monster High students). If you click on the students name this minie page will apeare. there will be a long white box on there. If you click on it you can write in the doll's code. But remember you need to put the right code in for the right name. I hope I helped. :-)
