ZIP code 03255

ZIP 03255 is a small town in Merrimack County, New Hampshire, with 1,957 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #152 of 246 ranked by population — larger than 38% of them. The median age here is 48.3 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in ZIP 03255 earn a median of $123,167 a year, 56.8% above the national figure of $78,538. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 2.7% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in ZIP 03255 is valued at $440,600, 45.2% above the national figure, while median gross rent runs $514 a month, 63.4% below the national figure, or roughly $6,168 across a full year. A household on the local median income would put about 5% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 3.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 88.9% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

All values below were released by the Census for this exact geography, with no gap-filling on our side. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.

ZIP 03255 is tabulated inside Merrimack County, New Hampshire, one of 28 ZIP areas the Census publishes for that county and 246 across New Hampshire. Fewer than 2,500 people are counted here, so the ZIP behaves like a village delivery route rather than a neighbourhood. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 03255 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 03255 reports a median household income of $123,167, 24% above the $99,237 county median, and 33% above the $92,797 typical NH ZIP. Owner-occupied homes are valued at a median of $440,600, 39% above the county figure and 30% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $514 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

New Hampshire charges 0% statewide, and no local sales tax is layered on top, so the state rate is the full amount collected in 03255.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 03255 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
