Portability happens within rate centres, not area codes.  In many places 
in the country, those usefully overlap, but not all.

For instance, here in Georgia, the NPA 706 is split across three 
geographically disparate regions, two of them in LATA 438, and one of 
them in LATA 442 (Augusta).

Thus, in order to be able to port a number to a different carrier, the 
receiving carrier needs to be interconnected in the right LATA, to the 
right ILEC, and have trunks on that interconnect to the right tandem to 
which the switch(es) in that rate centre are homed.  It's not just a 
matter of operating in the same state, or in the same NPA.
