Code-holder of record: METROPCS NETWORKS, LLC (OCN 899D), assigned June 22, 2007. The prefix is pooled: its ten thousands-blocks can be shared among several carriers, so different 909-205 numbers may be served by different companies.

Caller ID showing 909-205 is not proof the call came from San Bernardino: 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.
