device.uuid
Get the device's Universally Unique Identifier (UUID).
var string = device.uuid;
Description
The details of how a UUID is generated are determined by the device manufacturer and specific to the device's platform or model.
Supported Platforms
- Android
- BlackBerry WebWorks (OS 5.0 and higher)
- iPhone
- Windows Phone 7 and 8
- Bada 1.2 & 2.x
- webOS
- Tizen
- Windows 8
Quick Example
// Android: Returns a random 64-bit integer (as a string, again!)
// The integer is generated on the device's first boot
//
// BlackBerry: Returns the PIN number of the device
// This is a nine-digit unique integer (as a string, though!)
//
// iPhone: (Paraphrased from the UIDevice Class documentation)
// Returns a string of hash values created from multiple hardware identifies.
// It is guaranteed to be unique for every device and cannot be tied
// to the user account.
// Windows Phone 7 : Returns a hash of device+current user,
// if the user is not defined, a guid is generated and will persist until the app is uninstalled
//
// webOS: returns the device NDUID
//
// Tizen: returns the device IMEI (International Mobile Equipment Identity or IMEI is a number
// unique to every GSM and UMTS mobile phone.
var deviceID = device.uuid;

iOS Quirk
The uuid for iOS is not unique for a device, but is unique per application per install. This will change if you delete the app and re-install, and possibly also when you upgrade your iOS version, or even upgrade your app per version (as we've seen in iOS 5.1). Not a reliable value.
Windows Phone 7 and 8 Quirks
The uuid for Windows Phone 7 requires the permission ID_CAP_IDENTITY_DEVICE. Microsoft will likely be deprecating this property in the near future. If the capability is not available, the application generates a persistent guid, that will be maintained for the install-lifetime of the application on the device.
