Code-holder of record: T-MOBILE USA, INC. (OCN 6529), assigned January 8, 2001. The prefix is pooled: its ten thousands-blocks can be shared among several carriers, so different 512-586 numbers may be served by different companies.

Caller ID showing 512-586 is not proof the call came from Austin: 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.
