History of the 401 Area Code
The 401 area code was established in 1947 as one of the original area codes under the North American Numbering Plan (NANP). It has remained unchanged since its inception, serving the entire state of Rhode Island without any splits or overlays. The stability of area code 401 is attributed to the relatively small geographic and population size of Rhode Island, which has not necessitated additional area codes.
