By the way.....local calling areas don't usually change. Only when they 
do a rate center consolidation or break one apart which is quite rare. 
Once an NXX is assigned to a rate center, the rate center the NXX is 
assigned to also doesn't change. So once you have the rate centers 
documented for each local calling area, you really only need to add the 
new NXXs assigned to each rate center.  Just saying this in case someone 
wants to create their own resource.
