About PIN messages
A personal identification number (PIN) uniquely 
identifies each BlackBerry handheld on the 
network. If you know the PIN of another 
BlackBerry handheld user, you can send a PIN 
message to that person. PIN messages are not 
routed through an existing email account.
When your PIN message is delivered to the 
recipient, a D appears with a check mark in the 
messages list.
Find your PIN
In the handheld options, click Status.
Note:
If your handheld is integrated with an email 
account using the BlackBerry Enterprise Server 
version 4.0, your PIN is displayed on the 
Enterprise Activation screen.
