813 overlay codes and dialing
The 813 territory is covered by an overlay of 2 area codes: 656, 813. All of them serve the same geographic area, and the original code is 813. Because more than one code covers the same ground, 10-digit dialing is mandatory — you must dial the area code for every local call. New phone lines may be assigned any of these codes.

Is 813 a scam or spam risk?
813 is a legitimate geographic area code, not a premium or toll line, so a call from it costs you nothing extra. That said, scammers frequently spoof real local area codes to look familiar on caller ID. A genuine 813 number on your screen is no guarantee the caller is in Tampa, FL or trustworthy.
