NANPA's central-office code records list VERIZON PENNSYLVANIA, INC. (OCN 9208) as the code holder. Because 215-203 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.
Caller ID showing 215-203 is not proof the call came from Philadelphia 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.
