Overlay codes serving Tampa
Tampa is served by an overlay of 2 area codes: 656, 813. Because more than one code covers the same area, 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, so Tampa numbers are no longer tied to a single prefix.
History of the 813 area code
813 was introduced as an overlay to relieve number exhaustion in the Tampa area, adding capacity on top of 656 rather than splitting the region. Overlays let existing customers keep their numbers while new lines draw from the added code. Learn more in our overlay guide.
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 local or trustworthy.
