Treat the on-screen number as a hint, not evidence — 317-300 can be spoofed like any US prefix. If a call feels off, verify through an official callback number and file a complaint with the FCC or FTC.
NANPA's central-office code records list COMCAST IP PHONE, LLC (OCN 318J) as the code holder, assigned October 4, 2005. Because 317-300 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.
