Area code 456 is a telephone area code in the North American Numbering Plan that has been withdrawn from use and is available for a new assignment.
The area code was in use as non-geographic area code from 1993 until 2017 to route inbound calls from outside the territories of the North American Numbering Plan to specific carriers for carrier-specific services.[1][2]
In November 2017, the area code 456 was withdrawn because of lack of demand.[2][3] It was returned to the pool of unassigned codes in 2023 and is available for future assignment as a geographic NPA.
