Step 1: Find Your Model Number

You can find this by looking in your settings or by looking at your device.

Look in settings

Go to Settings > General > About. To the right of Model, you'll see the part number. To see the model number, tap the part number.

Look on your device

To find the model number, remove the SIM tray and look in the SIM tray slot. Make sure that you're in a place with bright light overhead. The model number is on the upper side—the side with the display.

On an iPhone 7 or earlier

Find the model number on the back of your device.
