History of Area Code 531
Area code 531 was established in 2011 as an overlay for area code 402 in eastern Nebraska. It was not created by dividing the 402 service area into separate sections. The overlay added numbering capacity while allowing existing customers to keep their 402 numbers.
Area code 402 was one of the original North American Numbering Plan area codes created in 1947, and it initially covered all of Nebraska. In 1954, western Nebraska received area code 308 after a split. Area code 531 later expanded numbering capacity in the remaining 402 region, and the overlay requires 10-digit dialing for local calls.
