Apple - Get iPad serial number on iCloud

I've found how you do it.

With Xcode installed, open your terminal and run:

open ~/Library/Preferences/com.apple.iPod.plist

This will open the property list editor.

Navigate down to Root -> Devices and look under each device to recognise the one you're looking for. There are 2 identifying factors: DeviceClass (which can be iPod, iPhone or iPad) and Firmware Version String. Through those two I was able to get the serial number I needed.

This will NOT work if you never registered and created an Apple ID!

• Login to icloud.com.
• At the top right you will see your little avatar (it's a circle and your name/Username will be next to it; click the name.
• At the bottom of the next page there will be listed all devices you have on that account.
• Select the appropriate one and the Serial number will come up and look like this, but with bullets: SERIAL *******KRTR4 (7 unseen characters) and the IMEI number will be below it with 10 unseen characters and 5 numbers, like this: IMEI **********68453.

Once you have completed this process above:

• Click manage at the top of this screen
• Reenter your account information
• Scroll down to device's then click view details
• Answer security questions
• Now your full serial number will be listed there.
