NANPA's central-office code records list METROPCS NETWORKS, LLC (OCN 899D) as the code holder, assigned March 21, 2007. Because 909-236 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.
Caller ID showing 909-236 is not proof the call came from Pomona: 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.
