New Hampshire State in United States

Description
New Hampshire, the Granite State, is known for its rugged White Mountains, charming towns, and pivotal role in presidential primaries. With no sales tax and a tradition of political independence, New Hampshire offers a unique blend of natural beauty and civic engagement.

The entire state is still served by a single area code — 603, which dates back to 1947. Despite population growth in cities like Manchester and Nashua, area code 603 has remained sufficient due to efficient number management. This makes it one of the few states to retain a single, iconic telecom identity.
