Area code 603

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 numbering plan areas in October 1947.

As of April 2011, area code 603 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 plan.[1] As a result of changes in allocation policies and a reclamation of a large block of previously allocated telephone numbers, including number pooling, the exhaustion time frame has been moved to at least 2032.[2]

Since New Hampshire has only one area code, callers in the state can reach any other telephone within the numbering plan area by seven-digit dialing.
