The assigned code holder is METROPCS, INC., operating company number 5562, assigned October 16, 2014. This is a pooled prefix — expect numbers within it to be split across more than one carrier in 1,000-number blocks.

Caller ID showing 619-551 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.
