Florida Public Service Commission Number Conservation Efforts Show Results

TALLAHASSEE — A series of telephone number conservation measures implemented by the Florida Public Service Commission (PSC) continue to show positive results. Since 1999, conservation initiatives have resulted in over 18.2 million fewer numbers issued to carriers, saving consumers from the expense and inconvenience of changing area codes.

The PSC initiated number pooling, allowing phone numbers to be allocated to service providers in blocks of 1,000, instead of 10,000 numbers. In addition, the PSC took back unused number blocks from carriers who did not assign them to customers.

Based on a recently completed analysis of area code exhaust dates for the United States, the projected exhaust dates for all of Florida’s area codes have been extended from 3 months to 2.5 years. Florida’s area codes and projected exhaust dates are included in the table below. The number of Florida area codes has expanded from 4 in 1994 (305, 407, 813 and 904) to 17 today, due to population growth and the increased use of cell phones and dial-up Internet services.

The 850 area code, which has a projected exhaust date in late 2011, will be the next area requiring relief.  The PSC will start relief plans for this area in late 2008, 36 months prior to the projected exhaust date.

The PSC has approved relief plans for the 305 and 407/321 area codes projected to exhaust in 2010. Area code 786 will overlay the Florida Keys, now served by area code 305, and area code 689 will overlay the area served by the 407/321 area codes.
The PSC is committed to making sure that Florida's consumers receive their electric, natural gas, telephone, water, and wastewater services in a safe, affordable, and reliable manner. The PSC exercises regulatory authority over utilities in the areas of rate base/economic regulation; competitive market oversight; and monitors safety, reliability, and service.
