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.

Why so?

  • \$\begingroup\$ Apple does that because they can. So they do. What use is this information to you anyway ? \$\endgroup\$ – Bimpelrekkie Jun 27 '17 at 19:41

    \$\begingroup\$ @Bimpelrekkie Information about FCC regulations could be quite useful for many people. While I don't directly deal with FCC regulations I find this question interesting and would like to know the answer for future reference. \$\endgroup\$ – Redja Jun 27 '17 at 20:20
  • \$\begingroup\$ None of these are for the US market, so why do they even have a FCC ID? \$\endgroup\$ – Passerby Jun 27 '17 at 21:55

I get the impression that Apple has done testing of different functions on multiple hardware with similarities.

From FCC:

enter image description here

The FCC IDs applies to different frequencies. Could be the Wifi / Bluetooth module is tested and filed under one number for a specific model, but the radio was tested on another model.

From 2643B test report: enter image description here Hints of similarities with 2643A except for the Wifi.

Usually similarity is used so you don't have to retest every configuration (memory, battery, etc) of a hardware. But the exact definition of similarity probably have to be discussed with FCC.
