Area code 402

From Simple English Wikipedia, the free encyclopedia

Area code 402 is an area code for Nebraska. It was one of the first codes created in 1947. It initially covered the entire state of Nebraska until 1954, which is when it was split by 308, which covers the western portion of the state, while 308 covers the eastern part of the state, including the towns Lincoln, Omaha, Columbus, Fremont, La Vista, and Norfolk. It was overlaid by 531 in March 26, 2011.[1] Permissive dialing in that area started on June 26, 2010 and ended on February 26, 2011, exactly a month before 531 was implemented.[2]
