Area code 205, Telephone prefix in Birmingham, Alabama, US
Area code 205 is a telephone prefix in Alabama covering the western and central portions of the state. It includes cities such as Birmingham, Tuscaloosa, Hoover, and many smaller towns across several counties.
AT&T established this prefix in 1947 as one of the original North American codes, and it initially covered all of Alabama. The territory later shrank as demand for telephone numbers grew, eventually focusing on the western and central portions of the state.
The area code connects communities across multiple counties, supporting communication networks for educational institutions, businesses, and residents throughout central Alabama.
In 2019, prefix 659 was added alongside 205 to meet growing demand for telephone numbers in the region. Both codes serve the same territory and are assigned to new numbers in parallel.
The service territory includes Jefferson County, home to Birmingham, the largest metropolitan area in Alabama. The region serves as an important economic hub in the southeastern United States.
