NANPA's central-office code records list COMMIO, LLC (OCN 939H) as the code holder, assigned June 8, 2017. Because 813-450 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.

Caller ID showing 813-450 is not proof the call came from Tampa Central: spoofing and porting both detach numbers from their origin. To verify a caller, hang up and dial the organization's published number, and report suspicious calls to the FTC.
