Area code 308 is the telephone numbering plan code for western Nebraska in the North American Numbering Plan. It was created on July 1, 1954, as a split from area code 402. The roughly S-shaped 308/402 line generally runs south to northwest, first along the Platte River easterly and then northwesterly along the eastern edge of the Sandhills.
This number plan area is one of the most sparsely populated in the nation. The bulk of the state's population and therefore telephone lines are located in the east. Under current projections, 308 will remain in its current configuration until at least 2033, not in danger of exhaustion.
