Overview
Understanding ZIP code 08561
ZIP code 08561 is assigned to Windsor, 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 381 people live inside it.
At 335 residents per square mile spread over 1.138 square miles, 08561 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.
Living here
What life in Windsor looks like
Housing in 08561 costs well above the national median. A typical home is valued at $479,500 against a US median of $207,500. The split between owning and renting is fairly even at 41.4% 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 100.0% of housing units here. The median construction year is 1957, making the housing here mid-century. At 0.0%, vacancy is low — housing here is tightly held.
The population skews considerably older than the national median, with a median age of 64.1 against 42 nationally. The average household holds 2.51 people, and 91.4% are family households.
Getting to work takes 18.5 minutes on average one way. The dominant mode is drove alone at 62.1% of workers, while 14.9% work from home. Commute patterns are one of the better proxies for how a place actually functions day to day.
Where to stay
Where to stay in Windsor, NJ
Windsor is a smaller community, so options inside 08561 may be limited to a handful of independent inns, motels or bed-and-breakfast properties. Travellers often widen the search to the surrounding area, where the choice is greater and prices are usually competitive.
For reference, Philadelphia, PA is about 37.0 miles away in a straight line, which is worth factoring in if you are comparing a stay here against one closer to the city centre.

Practical uses
What ZIP code 08561 is used for
Beyond addressing mail, 08561 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, 08561 offers a compact profile of Windsor: 381 residents, 36.3% of adults holding a bachelor's degree or higher, and an unemployment rate of 0.0%. 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. 08561 may cover parts of several distinct areas, and a single neighbourhood in Windsor 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.
