About Area Code 401
Area code 401 is a North American Numbering Plan (NANP) area code that has been in service since 1947. It is administered by NANPA on behalf of the FCC and serves the Rhode Island region anchored on Providence.
401 is currently a single-coverage geographic area code with no overlays. This means a 7-digit number in this area code is unique within its rate centers, though best-practice is always to dial the full 10-digit number when contacting a 401 line.
Mobile numbers in 401 are portable: a person who moved away from Providence may still carry a 401 mobile number on their device. If you receive an unexpected call from a 401 number, run it through the reverse lookup tool above for the most accurate, free identification.
