What you are looking for is a Blackberry PIN , and you can get it using the static method DeviceInfo.getDeviceID .
BlackBerry PIN is an eight-digit hexadecimal identification number assigned to each BlackBerry device. PIN codes cannot be manually changed by the device (although BlackBerry specialists can reset or update on the PIN server side) and are blocked for each specific BlackBerry. BlackBerry can communicate with each other using a PIN, directly or using the BlackBerry Messenger app. BlackBerry PINs are tracked by BlackBerry Enterprise Servers and the BlackBerry Internet Service, and are used to route messages to your BlackBerry device. Emails and any other messages, for example, from the BlackBerry Push service, are usually routed to the BlackBerry PIN. Then the message can be routed by the RIM network operations center and sent to the carrier, which delivers the message the last mile to the device. Example 2732E6DB
