Code-holder of record: OMNIPOINT COMMUNICATIONS MIDWEST OPERATIONS, LLC (OCN 2964), assigned February 24, 2015. The prefix is pooled: its ten thousands-blocks can be shared among several carriers, so different 317-798 numbers may be served by different companies.

Caller ID showing 317-798 is not proof the call came from Carmel: 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.
