Ontario is part of the Riverside-San Bernardino-Ontario, CA Metropolitan Statistical Area. For routing purposes it sits in LATA 730. Numbers here keep Pacific time.
The assigned code holder is TWC IP ENABLED SERVICES, LLC, operating company number 793K, assigned June 5, 2007. 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 909-218 is not proof the call came from Ontario: 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.
