Area code 402 is the original telephone numbering plan code for Nebraska in the North American Numbering Plan. 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 and new overlay area code 531 was implemented 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 in place.[1]
