The 401-291 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.

Code-holder of record: CSC WIRELESS, LLC (OCN 425J), assigned February 19, 2020. The prefix is pooled: its ten thousands-blocks can be shared among several carriers, so different 401-291 numbers may be served by different companies.

Caller ID showing 401-291 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.
