NANPA's central-office code records list T-MOBILE USA, INC. (OCN 6529) as the code holder, assigned February 11, 2002. Because 213-210 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.

Caller ID showing 213-210 is not proof the call came from Los Angeles:da 10: 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.
