Which iPhone model do you have? Here is where you have to look

you probably have a General idea of what iPhone you have—iPhone, 7, SE, 5s, X, and so on. But behind the marketing name, the each iPhone-configuration has its own model number. You normally don’t need to know this number, but it could be useful if you ever need to have more technical details about the device. Here is where you can find your iPhone model number and what is the meaning of this number.

What number is that?

Apple uses two numbering schemes for its devices. The first, what we call the “A” number (hat tip to The iPhone Wiki for the name) is a five-digit alpha-numeric string that begins with the letter A, followed by four numbers.

The second model is a number a five-digit alpha-numeric string that starts with the letter M, if the first letter can vary depending on the device. They are sometimes—but not always—see “LL/A” or something similar at the end of this series. We refer to this second number as a “SKU” in this article for the sake of clarity.

(Confusingly, Apple can’t even decide for yourself what each number is called in its documentation or on its devices. For example, Apple refers to the “A” number and the SKU, the “model” number, depending on where you look.) 

What is the difference? Basically, the “A” number is used to describe a model of the family (or revision thereof), as the iPad Air 2 with LTE, or the 13-inch MacBook Air in the rule. In the meantime, the SKU is used to describe a specific configuration of this model (for example, the 13-inch MacBook Air with 256 GB of memory). Otherwise, the “A is expressed,” – number is a common identifier, while the SKU is specific.

Starting with the iPhone 8, Apple stopped punching “A” – number on the back. But this information is still on the phone—it is in the operating system.

Here, both the “A” number and the model id is, how to find. On your iPhone 8 or later, tap the settings app. Tap on General, then Via. Scroll down to model number; this is the model-id-number/SKU.
