Finding the Identification Number of Your Device
Your device has a unique identification number. This number is referred to as the IMEI
(International Mobile Equipment Identity). You should keep a copy of this number. You
may require it, for example, when you access the Xperia™ Care support service to
register your device. Also, if your device is stolen, some network providers can use this
number to stop the device from accessing the network in your country or region.

Remove the SIM/memory card tray. Place a fingernail or other object with a long,
fine tip under the edge of the label strip, then drag the strip outward. The IMEI
