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 are specific to the device's platform or model.

Supported Platforms

  • Android
  • BlackBerry WebWorks (OS 5.0 and higher)
  • iOS
  • Tizen
  • Windows Phone 7 and 8
  • 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
// 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 on iOS is not unique to a device, but varies for each application, for each installation. It changes if you delete and re-install the app, and possibly also when you upgrade iOS, or even upgrade your app per version (apparent in iOS 5.1). The uuid is 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 deprecate this property soon. If the capability is not available, the application generates a persistent guid that is maintained for the duration of the application's installation on the device.
