It is always a question with your iPhone, iPad, and iPod touch to identify your model is from which generation as Apple always says with their new release of their iOS that this version will work only with & above ‘iPad Generation 4 Models’.
It will also help to identify other details like Apple Care Protection Coverage & Support, Manufacturing Details, Valid Purchase Date, Telephonic Technical Support if Active, and Repair & Service Coverage. Note: It will also work with your Macintosh and other Apple (Hardware) Products.
Then, to identify your Generation of Your iPhone, iPad, or iPod touch, follow these steps
Step 01:
Go to Settings > General > About > Serial Number
I hope it helps…
Thanks & Regards
