MDN  

  

Mobile Directory Number

 

The actual phone number one would dial to reach a specific mobile phone.

 

Prior to Wireless Number Portability, MDN was the same number as the MIN for many mobile phones. But now that MDN numbers can be ported (moved) to other carriers, MDN and MIN will be different for ported numbers.
