// October 25, 2011

There are several ways to locate your iPad’s serial number, UDID, IMEI and CDN. You can even get most of the numbers without the iPad as long as you have access to a computer that was used to back it up.

If you have the iPad handy, the serial and IMEI (IMEI is only on 3G models) are engraved right on the back of the iPad.
If you still have the original box that your iPad came in, you can get your iPad’s serial number and IMEI number on the barcode label that is affixed to the box.

You can also find your serial number on your iPad’s screen by going to Settings-> General-> About.

If you have a 3G model you will also find the Cellular Data Address, IMEI, ICCID and Modem Firmware.
