227 Area Code Overlay - Beginning June 14th 2023

To ensure a continuing supply of new telephone numbers, the Maryland Public Service Commission has approved an all-services area code overlay for the 240/301 area code region which serves all or portions of Aspen Hill, Bethesda, Bowie, Frederick, Gaithersburg, Germantown, Hagerstown, Potomac, Silver Spring, Waldorf, Wheaton, and many other small communities. The new 227 area code will serve the same geographic area currently served by the existing 240/301 area codes.

You will continue to dial the area code and phone number for all local calls, as you do today, within and between the 240, 301, and new 227 area codes.
