These are model Numbers of iPhone 5S. I want to know why two Model numbers of iPhones have the same FCC ID? I am assuming that as they are two models, they are NOT the same for Apple yet they have the same FCC ID . What constitutes a change of FCC ID and when does it take place?
Another example would be of iPhone 5 where Models A1428, A1429 and A1442 have the same FCC ID BCG‑E2599A.
