New Hampshire ZIP Codes

New Hampshire (NH) contains 248 ZIP codes spread across 10 counties and 238 distinct cities. Together those ZIP areas cover a total population of 1,316,573 based on Census ACS 5-Year Estimates. ZIP-level granularity matters here: New Hampshire stretches across very different economic zones, and a single state-wide average hides the 10x spread you will see between its highest-income and lowest-income ZIP codes in the table below.

The economic baseline across New Hampshire ZIPs shows an average median household income of $102,353 and an average home value of $404,868, with a state-wide average median age of 47.6. These averages are computed over every ZIP in NH with reported data, not weighted by population, so small rural ZIPs count the same as metropolitan ones. Use them as a reference line, then drill into the ZIP tables to see where affluent suburbs, rural counties, and urban cores deviate from the state mean.

The largest urban concentrations in New Hampshire by population are Manchester, Nashua, Concord, Derry, Dover, and each city aggregates multiple ZIP codes worth of Census data on its own city page. Every record in this view comes from publicly available federal datasets, primarily the U.S. Census Bureau American Community Survey and USPS ZIP Code Tabulation Area files, with no proprietary scoring, estimation, or editorial adjustment.
