Treat the on-screen number as a hint, not evidence — 414-308 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 PAETEC ITEL, LLC (OCN 829J) as the code holder, assigned December 30, 2008. Because 414-308 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.
