Area code 603 in Red

North American area code 603 is New Hampshire’s sole area code. 603 was created as one of the original area codes in October 1947.

As of April 2011, the 603 code was nearing exhaustion, and a second area code for New Hampshire was expected to be activated by 2013. Rather than a split, the New Hampshire Public Utilities Commission recommended that it be implemented as a statewide overlay, much as West Virginia had done in 2009 when its original area code, 304, was overlaid with 681.[1] However, due to the reclamation of a large number of stranded phone numbers, the exhaust date has moved back significantly, possibly beyond 2020.[2]

Since 10-digit dialing is not yet mandatory in New Hampshire, callers from telephones with the 603 area code do not need to dial 603-xxx-xxxx to reach other New Hampshire phone numbers.
