Find any 205- phone number in Alabama
The number 205 is an area code of the North American Numbering Plan (NANP). It is the area code assigned to most of the Birmingham metropolitan area, primarily surrounding Jefferson and Shelby counties in northern Alabama. The 205 area code was created in 1995 when it was split off from the existing 205. It was the first new area code for Alabama in almost three decades.
The North American Numbering Plan (NANP) is a system used to designate telephone area codes in multiple countries in the Caribbean, North America, and the Pacific Islands. It is administered by the North American Numbering Plan Administration (NANPA) and all countries that participate in the NANP abide by the same system. This system began in 1947 and is used to assign country codes, area codes, and exchange codes based on certain geographic areas. The NANP is also responsible for ensuring that no two telephone area codes overlap with each other.
