Treat the on-screen number as a hint, not evidence — 602-581 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 METROPCS, INC. (OCN 5562) as the code holder, assigned January 14, 2019. Because 602-581 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.
