Treat the on-screen number as a hint, not evidence — 513-517 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 CINCINNATI BELL (OCN 9348) as the code holder, assigned April 30, 2013. Because 513-517 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.
