Area code 456

Area code 456 was a non-geographic numbering plan area code (NPA) used until 2017 to route inbound calls from outside the territories of the North American Numbering Plan to specific carriers for carrier-specific services. In November 2017, NPA 456 was withdrawn because of lack of demand. The code is scheduled to be returned to the pool of unassigned NPAs in 2023.
