NPA
NPA stands for Number Plan Area, commonly called Area Code. "NXX" refers to the three digits of a phone number immediately following the area code, also called the "exchange" or the Central Office Designation. Each DID is typically made up of NPA-NXX-FDN. The FDN(Fixed Dialer Number) refers to the 4 digits that follow the NXX.
