Plainfield, NJ

ZIP code 07063 is assigned to Plainfield, NJ, and falls within Union 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 14,533 people live inside it.

At 8,142 residents per square mile spread over 1.785 square miles, 07063 reads as a densely built-up 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 run above the national median. At $89,840, 07063 sits comfortably in the upper half, ahead of 76% 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 07063 costs well above the national median. A typical home is valued at $363,000 against a US median of $207,500, and median gross rent runs $1,742 a month. The split between owning and renting is fairly even at 61.4% owner-occupied, which tends to indicate a mix of housing types rather than one dominant form.

The building stock is dominated by detached single-family houses, which account for 62.9% of housing units here. The median construction year is 1950, making the housing here mid-century. At 1.4%, vacancy is low — housing here is tightly held.

The population skews younger than the country as a whole, with a median age of 32.9 against 42 nationally. Households are relatively large at 3.58 people on average, with 83.3% classified as family households.

Getting to work takes 33.8 minutes on average one way. The dominant mode is drove alone at 60.6% of workers.

Beyond addressing mail, 07063 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, 07063 offers a compact profile of Plainfield: 14,533 residents, a median household income of $89,840, 21.0% of adults holding a bachelor's degree or higher, and an unemployment rate of 7.9%. 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. 07063 may cover parts of several distinct areas, and a single neighbourhood in Plainfield 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.
