Trenton, NJ

ZIP code 08629 is assigned to Trenton, NJ, and falls within Mercer 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 13,015 people live inside it.

At 16,454 residents per square mile spread over 0.791 square miles, 08629 reads as a dense urban 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 track close to the national picture. The median of $81,367 puts 08629 near the middle of the pack, ahead of 67% 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 08629 costs below the national median. A typical home is valued at $149,000 against a US median of $207,500, and median gross rent runs $1,263 a month. The split between owning and renting is fairly even at 67.4% 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 69.6% of housing units here. The median construction year is 1949, making the housing here mid-century. At 2.0%, vacancy is low — housing here is tightly held.

The population skews younger than the country as a whole, with a median age of 35.2 against 42 nationally. The average household holds 2.91 people, and 77.0% are family households.

Getting to work takes 23.2 minutes on average one way. The dominant mode is drove alone at 76.5% of workers.

Beyond addressing mail, 08629 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, 08629 offers a compact profile of Trenton: 13,015 residents, a median household income of $81,367, 14.8% of adults holding a bachelor's degree or higher, and an unemployment rate of 7.6%. 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. 08629 may cover parts of several distinct areas, and a single neighbourhood in Trenton 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.
