This dataset represents the telephone area codes of the North American Numbering Plan (NANP) area for use in telecommunications analysis. TGS uses this dataset for reference in the verification and quality assurance processes of other datasets. The dataset is a 2007 Q4 dataset representing the geographic telephone area codes, also known as Numbering Plan Areas (NPAs). Excluded from this dataset are area codes considered to be non-geographic NPAs (area codes designating a specific service rather than a specific geographic area), such as toll-free area codes which encompass the entire NANP area. These area codes are in a separate dataset called HSIP Toll Free Area Codes 2007 Q4 due to the magnitude of the shapes sizes, which when included in this dataset excessively retards the refresh rate making the dataset a cumbersome tool to use during the processing of other datasets.

Note: April 2017, MARIS staff used Select By Location tool to extract MS Data.
