Here are a few ways you might be able to find the model number, depending on the device you have.
On an iPhone 7 or earlier, some iPad models, or an iPod touch, find the model number on the back of your device.
To find the model number on an iPhone 8 or later model that has a SIM tray, remove the SIM tray and look in the 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.
If you have an iPhone without a SIM tray or an iPad that doesn't show the model number on the back, look in the USB-C or Lightning connector. Make sure that you're in a place with bright light overhead. Find the model number on the upper side of the connector—the side with the display.
