NANPA's central-office code records list BANDWIDTH.COM CLEC, LLC - CA (OCN 981E) as the code holder, assigned April 19, 2018. Because 213-320 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.

Caller ID showing 213-320 is not proof the call came from Los Angeles:da 01: 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.
