HACKETTSTOWN, NJ (Warren County) – Residents of several municipalities in the Hackettstown area may be surprised to learn that just because your mailing address says “Hackettstown,” it doesn’t necessarily mean you live within the town’s official boundaries.
Many areas in surrounding municipalities, including parts of Mount Olive Township (Morris County), Independence Township (Warren County), Washington Township (Morris County), Allamuchy Township (Warren County), and Mansfield Township (Warren County), share the 07840 zip code with Hackettstown. While this is convenient for postal purposes, it can lead to confusion about residency.
People often assume that the zip code determines where they live, but that’s not the case. It’s where you pay your property taxes that ultimately determines your municipality of residence.
For residents in the outlying areas, it’s important to confirm your township of residence for purposes such as voting, school district assignment, and local services. The mix-up can also affect eligibility for certain town resources, as those living outside Hackettstown’s actual borders may not qualify for programs specific to town residents.
You can verify your municipality by checking your property tax bill.
In the meantime, if you have a Hackettstown zip code, you should ensure you know exactly which municipality you call home.
