Area code 401 serves the entire state of Rhode Island and is one of the original area codes established in 1947. As the smallest U.S. state, Rhode Island has maintained a single area code despite changes in population and technology. The code includes cities like Providence, Warwick, and Newport. Known for its colonial heritage, vibrant arts scene, and coastal charm, the 401 area code is a symbol of statewide unity and pride. Seven-digit dialing remains common for local calls. The code is widely used in branding, politics, and media to evoke Rhode Island’s close-knit, historic character.
