NANPA's central-office code records list LEVEL 3 COMMUNICATIONS, LLC - VA (OCN 8825) as the code holder, assigned April 5, 2012. Because 757-550 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.

Caller ID showing 757-550 is not proof the call came from Norfolk Zone 1: 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.
