on June 1, 1997 at which time area code 240 was created as an overlay of area code 301. Area code 301 originally covered the entire state of Maryland, including Bethesda when it was put into service on June
1, 1947. Ten digit dialing (area code + seven digit number) is necessary in Bethesda, MD because two different homes in the same geographic area can have the same seven digit phone number but each
would have a different area code. |
