Montana Area Code Directory Information

The area code system was developed to make the telecommunications network easy to handle. The original plan was devised by AT&T and Bell Laboratories in the 1940s. It was then known as the North American Numbering Plan. The plan was implemented in the United States and Canada in 1947. The area codes were known as numbering plan areas as per the original plan.

Each US state was assigned single or multiple area codes as per the density of population and the number of existing telephone numbers.
