Code-holder of record: NEW CINGULAR WIRELESS PCS, LLC (OCN 6010), assigned October 2, 2014. The prefix is pooled: its ten thousands-blocks can be shared among several carriers, so different 916-586 numbers may be served by different companies.

Caller ID showing 916-586 is not proof the call came from Folsom: 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.
