Prefix 401-203 — Greenwich, RI
401-203 identifies a block of numbers in Greenwich, RI, within the 401 area code. Every US prefix is tied to exactly one rate center; this one is Greenwich.
The rate center lies in the Providence-Warwick, RI-MA Metropolitan Statistical Area. The serving LATA is 130. Local time follows the Eastern zone.
Treat the on-screen number as a hint, not evidence — 401-203 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 October 23, 2002. Because 401-203 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.
