The 227 NPA is still reserved for the relief of the 240/301 NPA,” Wayman said. “The 240/301 NPA exhaust was deferred more than 20 years and is now in need of relief. Heidi Wayman, the NANPA data management manager, said the 227 area code was assigned as relief for the 240/301 geographic area in November 2000, more than 20 years ago. The overlay also reserved a specific numbering plan area in case of an exhaust. The petition called for the adoption and implementation of the 240/301 Numbering Plan Area All-Services Distributed Overlay, a November 2000 order to relieve the 240/301 NPA in case of exhaustion. To approve the measure, the commission voted favorably on a petition by the North American Numbering Plan Administrator, an organization that allocates telephone numbering resources. The plan will not impact Baltimore, which uses the 410 and 443 area codes. “The remaining supply of available telephone numbers in the 240/301 area is estimated to be exhausted in the second quarter of 2023 - requiring the establishment of a new area code to support future demands in the region,” the statement read. In a statement released Wednesday, the commission said the move came in response to an estimate that expected the exhaustion of the 240 and 301 area codes by 2023. The area code is expected to span the same geographic area as the 240 and 301 area codes, which includes Allegany, Charles, Garrett, Montgomery, Prince George’s, St.

The Maryland Public Service Commission announced 227 as a new area code as early as 2023.
