Harkers Island, NC

ZIP code 28531 is assigned to Harkers Island, NC, and falls within Carteret 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 1,080 people live inside it.

At 482 residents per square mile spread over 2.241 square miles, 28531 reads as a small-town area. It is a sparsely populated postal code, 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 run below the national median. At $58,750, 28531 sits in the lower half, ahead of 30% 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 28531 costs close to the national median. A typical home is valued at $295,500 against a US median of $207,500, and median gross rent runs $968 a month. Ownership dominates: 84.2% 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 61.0% of housing units here. The median construction year is 1983, making the housing here from the later twentieth century. The vacancy rate of 62.3% is high, which in many places reflects seasonal or second-home use rather than abandonment.

The population skews considerably older than the national median, with a median age of 59.5 against 42 nationally. The average household holds 2.48 people, and 77.5% are family households.

Getting to work takes 33.6 minutes on average one way. The dominant mode is drove alone at 83.0% of workers, while 11.1% take public transit. Commute patterns are one of the better proxies for how a place actually functions day to day.

Beyond addressing mail, 28531 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, 28531 offers a compact profile of Harkers Island: 1,080 residents, a median household income of $58,750, 23.2% of adults holding a bachelor's degree or higher, and an unemployment rate of 0.5%. 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. 28531 may cover parts of several distinct areas, and a single neighbourhood in Harkers Island 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.
