Correct.....and the tariffs of the called party's carrier identify determine whether the calling party is making a local or toll call. Local calling areas are very weird with the ILECs because two rate centers can make a local call to the same rate center but if you make a call between those two rate centers it's considered toll. For example, in my area Franklin and Murfreesboro are considered local to Nashville, but a call between Franklin and Murfreesboro is toll.

The NPANXX of the CallingParty sets the rate center. The rate center sets the list of all local NPANXX for the CalledParty. If the CalledParty NPANXX is in the list then it is a local call.
LRN has nothing to do with it

You can port out of a rate center what u can't do is port out of a

how you route your tandem traffic vs VoIP traffic.
You can't port out of a rate centre.
