The 813 area code is one of Floridas original area codes, established in 1953. It was the second area code in Florida after 305 (Miami). Originally, 813 covered the entire west coast of Florida from the Panhandle to Naples.
Over the decades, 813 was split multiple times as Floridas population exploded. The 941 area code split off in 1996 (Sarasota), and 727 split off in 1998 (St. Petersburg/Clearwater).
In 2022, the 656 area code was added as an overlay to the same geographic region. Both 813 and 656 now serve the same area, so new phone lines may be assigned either area code. This means 10-digit dialing (area code + number) is required for all local calls. For regulatory details, visit the Florida Public Service Commission.
The Tampa Bay area is one of the largest metropolitan regions in the southeastern United States, with a diverse and growing economy:
Finance & Insurance
Healthcare
