Find any 251- phone number in Alabama

The 251 area code is a telephone area code in the North American Numbering Plan (NANP) of the Alabama Public Service Commission. 251 is the local area code for the Mobile area in south Alabama, including the cities of Mobile, Theodore and Prichard. The code was created in a split from the original code, 205, in the year 2001. Despite the split, the population of the Mobile area has continued to grow and has led calls to create a new area code, 938, to serve the growth.

The area codes are part of the NANP, which is a system used to designate different geographic locations for telephone numbers. All of the United States and parts of Canada, including the US Virgin Islands and most of the Caribbean have been assigned numbers within the NANP. The North American Numbering Plan Administrator manages the assigning of area codes and 1.9 billion NANP numbers. The system was created to ensure efficient use and allocation of telephone numbers and to maintain proper geographic divisions. The system is constantly expanding and evolving to account for the increasing need for telephone numbers.
