Whitehouse Station, NJ

ZIP code 08889 is assigned to Whitehouse Station, NJ, and falls within Hunterdon County. Like every US postal code, it began as a mail-routing device rather than a geographic boundary — the US Postal Service groups delivery routes under a single code so carriers and sorting equipment can process mail efficiently. Today it also serves as a practical shorthand for the area itself: roughly 10,539 people live inside it.

At 457 residents per square mile spread over 23.057 square miles, 08889 reads as a small-town area. It is a mid-sized postal code by population, and density shapes almost everything else on this page — how people get to work, whether they own or rent, and what housing costs.

Household earnings here sit well above the national picture. The median household income of $147,048 places 08889 in the upper reaches of American postal codes, ahead of 96% of them. The US median for comparison is $70,109. Bear in mind that median income describes the midpoint household, not the average — it is not pulled upward by a handful of very high earners the way a mean would be.

Housing in 08889 costs well above the national median. A typical home is valued at $523,100 against a US median of $207,500, and median gross rent runs $1,458 a month. Ownership dominates: 89.8% of occupied homes are owner-occupied, which usually signals an established residential area with relatively low turnover.

The building stock is dominated by detached single-family houses, which account for 89.7% of housing units here. The median construction year is 1979, making the housing here from the later twentieth century. At 1.3%, vacancy is low — housing here is tightly held.

The population skews considerably older than the national median, with a median age of 52.1 against 42 nationally. The average household holds 2.4 people, and 71.4% are family households.

Getting to work takes 35.7 minutes on average one way. The dominant mode is drove alone at 71.1% of workers, while 20.1% work from home. Commute patterns are one of the better proxies for how a place actually functions day to day.

Beyond addressing mail, 08889 does a lot of quiet administrative work. Retailers use it to calculate shipping and sales tax at checkout. Insurers use it to set premiums, since risk profiles vary geographically. Employers and marketers use it to define service areas. Government agencies use it to route benefits and organise reporting. If you have ever been asked for a postal code by a form that clearly does not intend to send you anything, this is why.

For anyone weighing a move, 08889 offers a compact profile of Whitehouse Station: 10,539 residents, a median household income of $147,048, 60.8% of adults holding a bachelor's degree or higher, and an unemployment rate of 4.9%. A handful of figures like these answer more relocation questions than most neighbourhood guides do.

One caution worth repeating: a postal code is not a neighbourhood. 08889 may cover parts of several distinct areas, and a single neighbourhood in Whitehouse Station may be split across more than one code. Boundaries also shift as USPS adjusts delivery routes. Treat the figures here as describing a delivery area, which is what they actually measure.
