'''Area code 456''' is a telephone [[area code]] in the [[North American Numbering Plan]] that has been withdrawn from use and is available for a new assignment.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.<ref>{{cite web
