Get the device's Universally Unique Identifier (UUID).
var string = device.uuid;
The details of how a UUID is generated are determined by the device manufacturer and specific to the device's platform or model.
- BlackBerry WebWorks (OS 5.0 and higher)
- Windows Phone 7 and 8
- Bada 1.2 & 2.x
- Windows 8
// 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;
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.
