History of 301 Area Code
Area code 301 was one of the first original area codes for the entire Maryland, established in 1947. Over time, as the need for telephone numbers increased, a new 410 area code was also created in 1991 to serve the eastern part of the state. As a result, western and southern Maryland were placed under the 301 area code. It faced limitations of phone numbers in the 1990s. Area code 240 was added as an overlay to the 301 phone number to minimize this issue.
This change required residents to adopt 10-digit dialing, leading to dissatisfaction among users. In June 2023, a third code, 227, was added to the area, making the latest change.
Today, 301 telephone numbers serve the communication needs of more than 1.5 million people in Maryland.
