Florida PSC Approves New Area Code for Hillsborough County

TALLAHASSEE — A new area code will be added to the existing 813 region, through an overlay implementation plan approved today by the Florida Public Service Commission (PSC).  The current supply of available 813 area code numbers is expected to run out during the third quarter of 2022.  The new overlay plan is intended to extend that supply.

The new area code will cover the same geographic boundaries of the current 813 area code. Existing telephone customers will keep their numbers, but new customers, or customers adding additional lines, will receive the new area code.  Everyone will have to dial the area code plus the seven-digit phone number to make local calls (10-digit dialing).  The PSC also approved a 13-month implementation schedule that includes a six-month customer permissive dialing period.

“As one of the most populous areas of Florida, Hillsborough county has thriving businesses and growing communities. Add all the new technologies that require telephone numbers to this, and it’s not surprising that a new area code is needed,” said PSC Chairman Gary Clark. “The approved overlay plan is customer-friendly. Current customers can keep their existing number, which is especially important to area businesses, and the six-month permissive dialing period will allow time for residents to adjust to 10-digit dialing.”

Phone numbers in Florida and throughout the United States are governed by the North American Numbering Plan Administrator (NANPA).  In April 2019, NANPA forecasted a need for 813 area code relief.  An industry meeting was held on September 16, 2019, and NANPA then filed a petition with the PSC favoring the “all-services distributed overlay plan.”  PSC staff held customer workshops on February 6, 2020 in Tampa, and February 7, 2020 in St. Petersburg to hear from affected customers directly.

The 813 area code was introduced in 1953. It was the second area code assigned in Florida, implemented when the 305 area code was running out of telephone numbers. Currently, the 813 area code serves all of Hillsborough county, the City of Oldsmar in Pinellas county, and the central and southeastern portions of Pasco county.

For more information about the area code changes, residents can contact their local telephone carrier or call the PSC’s customer assistance line at 1-800-342-3552.
