If you’re having a little trouble identifying your iPad, Apple has a page that identifies the year and the model of your iPad. You need to search for your model number at the back of your device between the FCC ID and the Serial Number. You’ll find some number that starts with an “A” similar to this “A1489.” On the Apple page, you need to search for your model number. It will tell you what iPad version do you have.
