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.
