ZIP Code 03231

ZIP code 03231, near Concord, ranks among the wealthier areas in the region, with per-capita income of $68,556 and a median home value of $604,800. That combination places households here well above the middle of the income range, and property values reflect it. The county-level effective property tax rate of 1.84% means a home at that median value would generate a substantial annual tax bill, so ownership carries a real cost even at these income levels. No combined sales tax applies within this ZIP, which offsets some of that burden on everyday purchases.
