Area code 239 covers southwestern Florida, including cities like Fort Myers, Naples, Cape Coral, and Marco Island. It was established in 2003 as a split from area code 941 to support population growth in the Gulf Coast region. Known for its beaches, golf courses, and seasonal residents, the 239 area is one of the most desirable retirement and vacation destinations in the country. The region has seen sustained development in healthcare, real estate, and tourism sectors. Area code 239 has become a marker of Florida’s upscale coastal lifestyle, especially in Collier and Lee counties. It remains a standalone code, with no overlay currently in place.
