NANPA's central-office code records list PEERLESS NETWORK OF ARIZONA, LLC - AZ (OCN 579F) as the code holder, assigned June 30, 2014. Because 602-483 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.

Caller ID showing 602-483 is not proof the call came from Phoenix: 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.
