NPA Code Description

An NPA is a Numbering Plan Area, also called Area Code. An NPA is the 3-digit code that occupies the A, B, and C positions in the 10-digit North American Numbering Plan (NANP) format that applies throughout the NANP serving area. NPAs are of the form NXX, where N represents the digits 2-9 and X represents any digit 0-9. For example:

In the NANP, NPAs are classified as either geographic or non-geographic:

• Geographic NPAs are NPAs which correspond to discrete geographic areas within the NANP serving area. These are also called Area Codes.
• Non-geographic NPAs are NPAs that do not correspond to discrete geographic areas, but which are instead assigned for services with attributes, functionalities, or requirements that transcend specific geographic boundaries.
