Mobile Identification # - what exactly is it?

I have a Verizon Wireless phone,


and I was looking at the settings,


and under "My Number,"


there are two numbers.


The first one is clear to me.


"Mobile Device #" and under it is my 10 digit phone number.


843-XXX-XXXX.


But the second one confuses me.


It's called "Mobile Identification #"


and the number is another 843-XXX-XXXX one.


But the number isn't familiar.


Anyone know what this means?


And, also, there's something called a "NAM".


What might that be?


Thanks for the help :)
