History of 609 Area Code
The 609 area code was introduced on January 1, 1957, as part of the North American Numbering Plan to serve central and southern New Jersey. At that time, it split from the original 201 area code, which had covered the entire state. By the late 1990s, the demand for new phone numbers grew rapidly due to the rise of cell phones, fax machines, and internet connections. To address this, the 609 area code was split in 1999, creating the new 856 area code to serve southwestern New Jersey.
In 2018, continued demand led to another change, but instead of splitting the code again, a new overlay area code, 640, was added to the same region. This meant that new phone numbers could use either 609 or 640. Today, 609 and 640 together cover central and southeastern New Jersey, including major cities and communities along the Jersey Shore.
