The 240 area code was introduced in 1997 as an overlay to the existing 301 area code. This change was implemented to accommodate the growing demand for new telephone numbers in the region. The overlay allowed for the continued use of the 301 area code while providing additional numbering options for new users. The introduction of area code 240 was part of a broader effort to manage the increasing need for telecommunications infrastructure in Maryland.
