The first area code to be introduced was 301 in 1947, which served the entire state until the other area codes were added to alleviate the growing demand for telephone numbers. Area codes 240 and 301 cover the western parts of Maryland, while area codes 410, 443, and 667 serve the eastern and southern parts of the state, including the Baltimore metropolitan area.
