Thomas Edison invented the phonograph and perfected the light bulb inside a laboratory that still stands today in a township that later took his name. Edison, New Jersey, sits squarely within this area code, home to the Edison Memorial Tower and a museum preserving the exact site where some of the most consequential inventions of the industrial age first came to life.

Splitting Away From an Exhausted Neighbouring Code
732 launched on June 1, 1997, splitting away from 908 as central New Jersey’s population boomed through the 1990s, driven by residents seeking proximity to both New York City and Philadelphia alongside the appeal of Jersey Shore living. That combination of urban access and coastal lifestyle made this corridor one of the fastest-growing parts of the state at the time.
New Jersey’s Oldest Township Sits Inside This Code
Woodbridge Township carries a genuinely remarkable colonial pedigree: settled in 1664, it stands as the oldest original township in New Jersey, receiving a royal charter directly from King Charles II of England in 1669. This same township hosted the state’s first gristmill and, in 1751, New Jersey’s first permanent printing house, a genuine concentration of colonial-era firsts packed into one small corner of what’s now a modern suburban commuter belt.
The Debate Over Whether “Central Jersey” Even Exists
This code has become an unlikely battleground in an ongoing New Jersey cultural argument: does “Central Jersey” exist as a genuine region, or is the state really just divided into North and South Jersey? Residents of this exact territory have leaned into the debate with genuine local pride, using their 732 area code as a rallying point in what’s become a good-natured but persistent regional identity dispute.
Where This Code Actually Reaches
732 spans a genuinely wide stretch running from inland suburbs to the Atlantic coastline:
- New Brunswick, home to Rutgers University
- Edison, Woodbridge, and Perth Amboy in Middlesex County
- Asbury Park, Long Branch, and Red Bank along the Jersey Shore
- Toms River and Lakewood in Ocean County
One detail that trips up even local guides: Toms River and Lakewood sit in Ocean County, not Monmouth County as frequently misreported, a distinction worth getting right given how often the two counties get confused in this particular territory.
A Corridor Built on Pharmaceuticals and Beach Tourism
This region supports a genuine concentration of pharmaceutical industry employment, layered directly against the seasonal tourism economy driving towns like Asbury Park and Point Pleasant Beach. That combination of steady corporate employment and beach-driven seasonal business gives 732 an economic identity considerably more varied than its shore-town reputation alone suggests.
Why 848 Joined as an Overlay in 2001
Even after splitting from 908, continued growth across this densely populated corridor pushed 732’s numbering pool toward exhaustion within just a few years, leading regulators to introduce 848 as an overlay in December 2001. Both codes now share identical territory, and calls between them are treated as local, though ten-digit dialing remains mandatory throughout the region.
Frequently Asked Questions
Q1. Is Thomas Edison’s actual laboratory still standing within this area code today?
The original Menlo Park laboratory site is preserved as part of the Edison Memorial Tower complex and Thomas Edison Museum in Edison Township, letting visitors see where Edison developed several of his most significant inventions.
Q2. Are Toms River and Lakewood really in Ocean County, not Monmouth County?
Yes, this is a common error worth correcting. Both towns sit within Ocean County, despite frequently being misfiled under Monmouth County in guides covering this region.
Q3. Does a 732 number mean the caller is more likely near the Jersey Shore or in an inland suburb?
It could be either. This code spans both densely populated inland suburbs like Edison and Woodbridge and classic shore towns like Asbury Park and Long Branch, so the code alone doesn’t indicate which environment the caller is in.
Q4. Can a business outside New Jersey get a 732 number to establish a Central Jersey presence?
Yes, virtual number providers commonly issue 732 or 848 numbers to businesses anywhere, letting them establish a central New Jersey or Jersey Shore presence for pharmaceuticals, tourism, or general business outreach without needing a physical office there.
