305-464 identifies a block of numbers in Miami, FL, within the 305 area code. Every US prefix is tied to exactly one rate center; this one is Miami.

The rate center lies in the Miami-Fort Lauderdale-Pompano-West Palm Beach, FL Metropolitan Statistical Area. The serving LATA is 460. Local time follows the Eastern zone.

Treat the on-screen number as a hint, not evidence — 305-464 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 OMNIPOINT MIAMI E LICENSE, LLC (OCN 6889) as the code holder, assigned February 8, 2022. Because 305-464 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.
