Within a few days after the registration Apple will probably call you and ask you a few questions to make sure that your intentions for the app are in line with the Apple guidelines. Here are possible questions and some ideas for your answer:
Q: What is the name of the company that registers? A: The name should be the same that was used to register for the D-U-N-S number.
Q: What department does the contact person works in? A: Just state the department where you (the contact person for Apple) work.
