33 reactions · 32 comments | Our 603 area code is a point of pride in New Hampshire. One state. One area code. One community. That's why I signed an Executive Order for NH to take every step possible to ensure that "603" remains our only area code for many more years to come. Don't Overload the Code! ☎️ | Governor Chris Sununu | Facebook
