Code-holder of record: CENTURYLINK COMMUNICATIONS, LLC (OCN 508J), assigned February 17, 2015. The prefix is pooled: its ten thousands-blocks can be shared among several carriers, so different 512-409 numbers may be served by different companies.

Caller ID showing 512-409 is not proof the call came from Bastrop: 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.
