How to tell which iPad model you have
Apple identifies all its iPads with "iPad" on the back. Not "iPad 2." Not "The New iPad." Just "iPad." As simple as this naming convention seems, it can cause plenty of frustration—just ask anyone who's ever tried to tell two seemingly identical iPads apart. Argh. It's easier than you think to find an iPad's model number—but you might need a magnifying glass.
Apple's model numbering system for the iPad denotes which generation iPad you have, as well as its wireless connectivity capabilities (whether it's a Wi-Fi model or has Wi-Fi and cellular modules inside). This is different from the SKU, which also denotes your iPad's storage capacity, color, and so on.
The model number is stamped onto the device itself. These model numbers usually start with the letter A and are followed by four digits. You can find this number on the back of your iPad: Flip it over, and look for the "iPad" label toward the bottom. You'll find the model number and serial number in this small text, and on older models, your iPad's storage capacity.
Look closely at the fine print on the back, and you'll find your iPad's model number and serial number.
Here's a chart to help you understand what it all means:
