There are quite a lot of numbers and identifiers available for each device in the world, which differentiates between the same device product by different users. When we talk of the phones, smartphones it is the IMEI number that holds the importance, but when it is about the tablet devices and non-phone gadgets, the serial number is an important one. Let’s see what all are the important numbers and identifiers to keep a note of:

Serial Number – For all the Devices – iPhone all versions, iPod Touch, iPad Mini, iPad all generations

Numbers for Devices with Cellular Connectivity:

• IMEI – International Mobile Equipment Identity number
• CDN – Cellular Data Number
• ICCID – Integrated Circuit Card ID

Finding the Serial Number of the iPad, iPhone, iPad Mini and iPod Touch

The serial number of all the Apple handheld devices is provided on two places – The back panel in the bottom section where a lot of text is engraved, including the Serial Number, and the Settings section where the About section for the device would show the serial number. Turn your device back and check the bottom for the engraved text to get the serial number. This comes to good use when your device is turned off or isn’t working and the Apple Care asks for the serial number of the product for verification.

If the device is turned on, you can easily find the serial number by going to the Settings > About where the serial number is located.

To copy the IMEI, ICCID etc. you need to be on the iOS 6 or later on your device. Tapping and holding the number for a couple seconds would open an option to copy the number. This would make it better for an accurate entering of the data when you are filling some forms on the registration sites etc.
