Area code 732 covers Central New Jersey, including Middlesex and Monmouth counties, northern Ocean County and parts of Somerset and Union counties. Major places include Edison, New Brunswick, Woodbridge, Toms River, Lakewood, Freehold and Long Branch. It was split from area code 908 in 1997, and the overlay code 848 was added in 2001, which is why everyone in the region dials 10 digits for local calls. As of April 2026, national numbering administrators project that the 732/848 pair will not run out of numbers until about 2051.

Where Is Area Code 732?
Area code 732 sits between the New York metro area and the southern half of the state. It runs from the Raritan Bay and the Middlesex County towns near Staten Island, through the Rutgers area in New Brunswick, and down the Monmouth County coast into northern Ocean County.
In other words, area code 732 matches what many residents call Central Jersey, plus the northern Shore. However, borders do not follow county lines exactly. Some towns use more than one area code, and some Union County towns near 732 territory, such as Linden, use 908 instead.
Towns and Cities in Area Code 732
| County | Examples of towns served | Notes |
|---|---|---|
| Middlesex | Edison, New Brunswick, Woodbridge, Perth Amboy, Carteret, Old Bridge | Core of the code; Piscataway uses both 732 and 908 |
| Monmouth | Freehold, Red Bank, Long Branch, Asbury Park, Howell | Northern Jersey Shore communities |
| Ocean | Toms River, Lakewood, Brick | Northern Ocean County; southern areas use 609 |
| Union | Rahway | Only part of the county; much of Union uses 908 |
| Somerset | Parts of Franklin Township | Franklin is served by 732, 908 and 609 |

History of Area Code 732
New Jersey’s area codes have been split and overlaid several times as demand for phone numbers grew with fax lines, pagers and cell phones. Area code 732 is a product of that growth.
| Year | What happened |
|---|---|
| 1991 | Area code 908 is created from part of 201 to serve central and western New Jersey. |
| 1997 | The eastern part of 908 is split off to form area code 732, after a period when both codes worked. |
| 2001 | Area code 848 is added as an overlay on the same territory as numbers in 732 run low. |
| 2001 | Mandatory 10-digit dialing begins for local calls in the 732/848 region. |
| 2026 | NANPA’s April forecast projects 732/848 exhaust in the third quarter of 2051. |
As a result of the split, many longtime residents and businesses had to change their area code in 1997, even though they kept the same seven-digit number.
Area Code 732 and the 848 Overlay
An overlay adds a second area code to the same geographic area instead of splitting it. That means a new phone line in Edison or Toms River might receive either a 732 or an 848 number, depending on what is available when the number is assigned.
Because two area codes cover the same towns, the area code is needed to tell calls apart. For that reason, all local calls in the region require 10-digit dialing. For example, calling a neighbor across the street still means dialing the area code first.
| Question | 732 | 848 |
|---|---|---|
| Territory | Central NJ and northern Shore | Same as 732 |
| In service since | 1997 | 2001 |
| Type | Original code for the region (split from 908) | Overlay |
| Local calls | 10 digits | 10 digits |
How Area Code 732 Compares With Other NJ Codes
NANPA publishes forecasts of when each area code will run out of numbers. Its April 2026 report shows the 732/848 region has decades of supply left, while two single codes in the state are closer to needing relief.
| Area code(s) | General region | Projected exhaust (April 2026) |
|---|---|---|
| 201/551 | Hudson and Bergen counties | 2nd quarter 2048 |
| 973/862 | North Jersey, including Newark | 3rd quarter 2052 |
| 908 | Union, Somerset, Hunterdon, Warren and nearby areas | 3rd quarter 2039 |
| 732/848 | Central Jersey and northern Shore | 3rd quarter 2051 |
| 609/640 | Mercer County, the southern Shore and Atlantic City | 3rd quarter 2046 |
| 856 | South Jersey near Philadelphia | 1st quarter 2035 |
These dates are forecasts, not deadlines, and NANPA updates them twice a year. For the full statewide picture, see our guide to NJ area codes.
Neighboring Area Codes
- 908: West and north of 732, covering much of Union and Somerset counties plus Hunterdon and Warren. It has no overlay.
- 609 and 640: South and southwest, including Trenton, Princeton, southern Middlesex towns such as Plainsboro and Cranbury, and the southern Shore. The 640 overlay began on September 17, 2018.
- 201 and 551: Hudson and Bergen counties to the north.
- 973 and 862: Essex County and other North Jersey areas.
Getting an Area Code 732 Number
Phone carriers assign new numbers from the blocks they hold in each area. Since the overlay, a new line in the region can come with either a 732 or an 848 number, and carriers do not guarantee one code over the other. If you specifically want an area code 732 number, ask your carrier before activation whether any are available at your location.
In addition, federal number portability rules generally let you keep an existing number when you switch carriers. As a result, many people who move away from Central Jersey keep their 732 mobile number for years, so an area code 732 caller may not live in New Jersey at all.
Businesses that want a local image in the region can list either code. Customers in Middlesex, Monmouth and northern Ocean counties see both 732 and 848 as local numbers.
Tips for Calls From Area Code 732
- Save contacts with the area code. Because of 10-digit dialing, a seven-digit entry may not connect.
- Do not assume 848 is out of state. An 848 number is just as local as a 732 number.
- Be cautious with unknown calls. Caller ID can be spoofed, so a familiar area code 732 number is not proof that a caller is local or legitimate.
- Check both codes when searching. A business in New Brunswick or Lakewood may list either code.
- Update alarm and fax equipment so it dials the full 10-digit number.
Living and Working in Area Code 732
