The 240 area code was created in 1997 as a split from the original 301 that once covered all of Montgomery County and parts of surrounding areas. Today, 240 is exclusively tied to Montgomery County, Maryland, encompassing cities like:
Silver Spring – a vibrant suburban area with a lively downtown
Rockville – the county seat with a blend of urban and suburban charm
Gaithersburg – known for its diverse population and community centers
For generations, 240 has represented Maryland pride, offering the best of suburban life with fast access to Washington, D.C.
The 240 area code operates in the Eastern Time Zone (ET)–the same time zone as Montgomery County. This is important for businesses and professionals who need to stay in sync with local clients, suppliers, and partners. Whether you’re scheduling calls, running local ads, or managing customer support, having a 240 number means you’re aligned with Eastern Standard Time (EST) in winter and Eastern Daylight Time (EDT) in summer.
