New Hampshire Phone Numbers and Area Codes

Area code 603 is the sole area code for the U.S. state of New Hampshire in the North American Numbering Plan (NANP). It was created as one of the original 86 North American area codes in October 1947. Due to New Hampshire's low population density and growth rate, the state has yet to need an additional area code. As a result, 603 is one of the few original area codes that have never been split or overlaid.

New Hampshire has the lowest share of adults without phones in the nation at 0.5%.
