New Hampshire is home to 218 ZIP codes that cover all 10 counties and roughly 200 cities and towns across the Granite State. Ranging from 03031 in the southern town of Amherst to 03894 in the lakeside community of Wolfeboro, these ZIP codes span a diverse landscape of seacoast communities, mountain towns, and vibrant urban centers like Manchester and Nashua. Every New Hampshire ZIP code begins with the digits 03, making it one of the most uniform states in the nation for postal addressing. Rockingham, Hillsborough, and Grafton counties contain the greatest concentration of ZIP codes, reflecting the state's population centers and its many charming New England towns.
New Hampshire ZIP codes all begin with the prefix 03, reflecting its position within the New England sectional center. The prefixes range from 030 through 038, generally progressing from the southern population centers near Manchester and Nashua (030–031) northward through the Lakes Region (032–033), the Upper Valley and Grafton County area (034–037), and into the eastern seacoast and Carroll County regions (038). This compact prefix range mirrors New Hampshire's relatively small geographic footprint.
Rockingham County leads New Hampshire with 36 ZIP codes, which is largely attributable to its position as the state's most populous county, its extensive seacoast geography, and its numerous distinct towns and communities stretching from the Massachusetts border to the coastal areas around Portsmouth and Hampton.
