Find any 531- phone number in Nebraska

The 531 area code is part of the North American Numbering Plan (NANP). This system designates telephone numbers that are used across the United States, Canada, and some Caribbean countries. 531 is an area code that was created in 1997 as an overlay to the 402 area code, which previously served all of the state of Nebraska.

The 531 area code is used in Nebraska to identify telephone numbers serviced in a few distinct counties in the eastern part of the state, including Lancaster, Saunders, and York counties. The 402 area code still serves numerous locations across Nebraska, however 531 is the exclusive area code used in more localized areas. All calls made in the United States, which includes both 531 and 402 numbers, require the ten-digit dialing system. This system involves dialing 1 before the area code and seven-digit phone number for each call placed.
