NANPA's central-office code records list NEW CINGULAR WIRELESS PCS, LLC (OCN 6010) as the code holder, assigned June 14, 2012. Because 619-289 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.

Caller ID showing 619-289 is not proof the call came from Chula Vista: 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.
