- Abstract
- United States Telephone Area Code Boundaries is a polygon theme representing the telephone area codes for the United States. They are also known as Numbering Plan Areas (NPA). The Numbering Plan Areas reflect current and accurate boundary changes both where new NPAs "split" from existing NPAs and where new NPAs "overlay" existing NPAs.
- Purpose
- U.S. Telephone Area Code Boundaries provides the telephone area codes of the United States for use in telecommunications analysis.
- Supplemental Information
- Largest scale when displaying the data: 1:250,000. This dataset includes an ESRI layer file which symbolizes and labels the features.

- Data Quality Information
- Logical Consistency Report
- The shapefile is converted to SDC (Smart Data Compression) format using either tools in ArcGIS or ESRI SDC Data Development Kit Professional 2 (DDKP2). The SDC data set is then imported into a file geodatabase to verify and validate the geometry.
- Completeness Report
- After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials.
- Horizontal Positional Accuracy Report
- The horizontal positional accuracy is difficult to determine since the boundaries may follow state, county, city, or other political boundaries. Still other times they may follow streets or other linear features in the database. Since these features are derived from different sources, it is not possible to give a single overall figure for horizontal accuracy.
