History of the 609 Area Code

The 609 area code was established in 1957, making it one of the original area codes in New Jersey. Over the years, the demand for new phone numbers increased, leading to changes in the area code's structure. In 1999, area code 609 underwent a split, resulting in the creation of area code 856 to serve the southwestern part of New Jersey. In 2018, area code 640 was created and is currently an overlay to 609. This change was necessary to accommodate the growing population and the proliferation of mobile devices.
