Area code 240 is an overlay that shares territory with the original 301 code across suburban Maryland west of the Chesapeake Bay. The region includes the Montgomery and Prince George's Counties — two of the most educated and affluent counties in the US due to their proximity to Washington DC. It was introduced in 1997.
Across मैरीलैंड, the 240 area code serves roughly 1.4 million residents in 4 communities — including Rockville, Gaithersburg, Frederick, among others.

240 was first introduced in 1997 as an overlay of the 301 area code, adding fresh numbering capacity to the same region without forcing anyone to change an existing number. Because an overlay shares geography with another code, ten-digit dialing is standard throughout the area. It remains an active overlay code today.
