Area code 402 is the telephone numbering plan code for eastern Nebraska in the North American Numbering Plan. It was one of the original area codes created in 1947, and served the entire state. In 1954, this area code was split: eastern Nebraska retained 402, and western Nebraska was placed in area code 308. The roughly U-shaped 308/402 line generally runs (from south to north) northeast along the Platte River and then northwest along the eastern edge of the Sandhills.
The area code is nearly exhausted due to the presence of the state's two largest cities, Omaha and Lincoln--which are also home to most of the state's fax machines, cell phones and pagers. It was originally projected to exhaust in 2001, but number pooling was implemented to stave off exhaustion. In 2009, however, NeuStar projected that 402 would exhaust in 2010. Area code 531 was implemented as an overlay across the 402 area in March 2011. The first 531 prefixes will be assigned when 402 is near fully exhausted; however, 10-digit dialing is already in place.
