The 401-390 prefix belongs to area code 401 and is anchored to the Providence rate center (RI). In NANP terms, the prefix — or NXX — determines the rate center a number is billed against.

Providence is part of the Providence-Warwick, RI-MA Metropolitan Statistical Area. For routing purposes it sits in LATA 130. Numbers here keep Eastern time.

NANPA's central-office code records list METROPCS, INC. (OCN 5562) as the code holder, assigned March 6, 2008. Because 401-390 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.

Caller ID showing 401-390 is not proof the call came from Providence: spoofing and porting both detach numbers from their origin. To verify a caller, hang up and dial the organization's published number, and report suspicious calls to the FTC.
