📍 Geographic Location of Florida
Geographic Coverage and Administration
Area code 239 is a geographic North American Numbering Plan Area (NPA) code serving the southwestern coast of Florida. It is administered by the Florida Public Service Commission and currently provides numbering resources for Lee and Collier counties, encompassing the cities of Fort Myers, Cape Coral, Naples, Bonita Springs, Estero, and Marco Island. The numbering plan area also covers the communities of Lehigh Acres, Golden Gate, and Ave Maria. As a geographic code, 239 is assigned to wireline, wireless, and VoIP services that are physically located within this region, although number portability allows subscribers to retain their 239 numbers when moving within the same rate center.
Dialing Formats and Procedures
For local calls within the 239 area, callers must use the 10-digit dialing format: 239-XXX-XXXX. This includes calls between different exchanges within the same NPA. For calls originating from outside the 239 area but within the United States or Canada, the international format is +1 239 XXX XXXX (or 1-239-XXX-XXXX when dialing from a landline). When calling from abroad, the country code for the United States is +1, so the full international number is +1 239 XXX XXXX. For example, a caller in London would dial 00 1 239 555 0123 to reach a number in Naples.
Overlay and Numbering Resources
Currently, 239 is the sole area code serving this region; however, due to growing demand, an overlay area code has been proposed. In an overlay scenario, new numbers may be assigned with a different area code, but existing 239 numbers remain unchanged. All calls within the overlay area would require 10-digit dialing, which is already in effect. Businesses and residents should be aware that future assignments may not carry the 239 code, but the geographic coverage remains identical.
Caller Instructions
For local callers: simply dial the 10-digit number (area code + 7-digit subscriber number). For long-distance callers within the US/Canada: dial 1 followed by the 10-digit number. For international callers: dial your country's exit code, then 1, then 239, then the 7-digit number. Always verify the number of digits; 239 numbers are always 10 digits in total (including area code) for local dialing.
