What is the 347 Area Code?

The 347 area code was introduced as part of a strategic telecommunications expansion to address the increasing demand for phone numbers in New York City’s outer boroughs. It covers the same geographic territory as area code 718, operating as an overlay system that allows multiple area codes to serve the same region.

History of 347 Area Code

When Was 347 Created?

The 347 area code was established on October 1, 1999, making it the 267th area code put into service in North America. The creation of 347 was necessary due to the rapid growth in population and the unprecedented demand for phone numbers in the late 1990s, fueled by the proliferation of cell phones, fax machines, and dial-up internet connections.

The telecommunications industry recognized that the existing 718 area code was approaching exhaustion and needed additional number capacity to serve the growing population and business needs of New York City’s outer boroughs.

Area Code Changes and Overlays

The evolution of NYC area codes began with all five boroughs using the single 212 area code until 1984, when 718 was created for Brooklyn, Queens, and Staten Island. In 1992, area code 917 was introduced initially for mobile phones and pagers.

In 1999, the 347 area code was implemented as an overlay for the 718 territory, followed by area code 929 in 2011 as another overlay to meet continued demand. A new area code 465 is scheduled to overlay the numbering plan area on June 18, 2026.
