The rate center lies in the Atlanta-Sandy Springs-Roswell, GA Metropolitan Statistical Area. The serving LATA is 438. Local time follows the Eastern zone.
Treat the on-screen number as a hint, not evidence — 404-637 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 POWERTEL ATLANTA LICENSES, INC. (OCN 7473) as the code holder, assigned January 27, 2012. Because 404-637 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.
