239 Area Code: Fort Myers, Cape Coral, Naples & Southwest Florida Guide

Introduction

Southwest Florida occupies a distinctive position in the American imagination — a sun-drenched Gulf Coast corridor where retirees from the Midwest and Northeast have built some of the wealthiest communities per capita in the United States, where developers carved more than 400 miles of navigable canals through a coastal city that now rivals the population of Cincinnati, and where Thomas Edison and Henry Ford built adjacent winter estates that still define Fort Myers' civic identity. The 239 area code, activated in 2002 when it split from the 941 code covering the Sarasota region, serves Lee and Collier counties in full — Fort Myers, Cape Coral, and Naples along with their surrounding communities — plus a small rate-center edge reaching into Charlotte County.

For businesses reaching the 239 region's healthcare and medical device industry — anchored by Arthrex's orthopedic headquarters in Naples and Lee Health's hospital system in Fort Myers — the luxury hospitality network around Naples and Marco Island, or Cape Coral's residential construction boom, a virtual 239 phone number from letsdial delivers trusted southwest Florida presence with same-day activation.

• Covers Lee and Collier counties in full — Fort Myers, Cape Coral, Naples, and Marco Island — plus a small edge into Charlotte County
• Split from 941 in 2002; no overlay, so seven-digit local dialing still works across most of the territory
• Eastern Time Zone; home to Arthrex, Lee Health, and southwest Florida's luxury resort economy

What Is the 239 Area Code?

The 239 area code is a geographic NANP code covering southwest Florida — primarily Lee and Collier counties. Florida was originally served by area codes dividing the state roughly north and south, with 813 covering most of western and southwestern Florida for decades. As Florida's population exploded along the Gulf Coast retirement corridor, 813 was progressively subdivided. On May 28, 1995, 941 was split from 813 to serve the southwest Gulf Coast including Sarasota, Manatee, Charlotte, Lee, and Collier counties, while 813 retained the Tampa Bay area.

By the early 2000s the 941 territory was running low on number blocks. Rather than an overlay, regulators chose a geographic split: 239 went into service on March 11, 2002, carved from the southern portion of old 941 — Lee and Collier counties, plus a small edge into Charlotte County. The 239 area code has no overlay, and seven-digit local dialing remains available throughout much of the territory. Neighboring area codes include 941 (Sarasota/Manatee to the north), 863 (Polk County and the inland Hendry/Glades communities to the east), and 305/786 (Miami-Dade to the southeast). More detail sits on our virtual 239 phone number page.

Cities and Communities in the 239 Area Code

The 239 area code spans Lee County (Fort Myers, Cape Coral, Sanibel, Bonita Springs, Estero, Lehigh Acres) and Collier County (Naples, Marco Island, Immokalee, Ave Maria, Golden Gate), plus a small edge into Charlotte County. LaBelle, Clewiston, and Moore Haven sit close by on the map but are actually served by area code 863, not 239. The major population centers:

• Cape Coral (Lee County, ~233,000) — 400+ miles of navigable canals, the most of any city in the world; one of Florida's fastest-growing cities
• Lehigh Acres (Lee County, ~150,000+) — large unincorporated planned community east of Fort Myers with rapid population growth
• Fort Myers (Lee County, ~100,000) — Lee County seat, Edison & Ford Winter Estates, downtown arts district, Lee Health HQ
• Bonita Springs (Lee County, ~57,000) — growing Gulf Coast community and luxury residential corridor between Fort Myers and Naples
• Estero (Lee County, ~35,000) — Florida Gulf Coast University, Miromar Outlets, Coconut Point, rapid commercial growth
• Naples (Collier County, ~20,000 city / ~410,000 county) — ultra-luxury resort, Fifth Avenue South, among the highest per-capita incomes in the US, Arthrex HQ
• Immokalee (Collier County, ~25,000) — major US tomato and winter-vegetable farming hub and agricultural workforce center
• Marco Island (Collier County, ~18,000) — barrier-island luxury resort, JW Marriott, boating and fishing

> [TIP] Note: Did You Know: Cape Coral has more miles of navigable canal waterways than any other city in the world — over 400 miles, surpassing even Venice, Italy. Originally platted in the 1950s and 60s, its canal network gives tens of thousands of homes direct Gulf of Mexico boating access and consistently ranks the city among the fastest-growing in the United States.

Business Landscape: Economy and Key Sectors

The 239 area code spans two economic personalities — Lee County's urbanizing residential and healthcare economy around Fort Myers and Cape Coral, and Collier County's ultra-high-income resort market around Naples and Marco Island — plus an agricultural economy in Immokalee and a growing university presence in Estero.

Straddling the Lee-Charlotte county line, Babcock Ranch opened in 2018 as America's first solar-powered town — a 17,000-acre planned community built around an 870-acre solar farm generating 150 megawatts from roughly 680,000 panels. The development proved its resilience during Hurricane Ian in 2022, when Babcock Ranch kept power and avoided major flooding while surrounding communities lost electricity for days, drawing national attention to the 239 region's growing reputation for climate-resilient planned development.

• Lee Health and regional healthcare (Fort Myers) — one of Florida's largest public health systems, with four acute-care hospitals and over 12,000 employees; NCH Healthcare System anchors Collier County
