Area code 603
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. However, due to the reclamation of a large number of stranded phone numbers, the exhaust date has moved back significantly, possibly beyond 2020.
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.
