Code-holder of record: COMCAST IP PHONE, LLC (OCN 318J), assigned March 3, 2017. The prefix is pooled: its ten thousands-blocks can be shared among several carriers, so different 317-516 numbers may be served by different companies.

Caller ID showing 317-516 is not proof the call came from Fishers: 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.
