What’s the difference between “A” number and “SKU” or Model name?
Apple uses 2 different numbering systems for its devices. Both are interchangeably referred to as “model” number by Apple. Basically, “A” number is a more generic identifier, used to describe a family of devices, whereas “SKU” or model number is used to describe a specific configuration of that model, including color and storage space.
How to find your iPhone 8 model identifier and “A” number?
On your iPhone 8 tap Settings, then go to General, and select About. Scroll down to Model Number. This is the SKU. To learn your A number, tap the Model number one time, and it will change to a numeric string that starts with A.
