The 559 area code is one of 72 area codes in the North American Numbering Plan (NANP). This numbering plan was established in 1947 to keep track of telephone numbers throughout the United States and Canada. This plan divides the entire continent into area codes based on a specific numbering pattern and geographical boundaries. Each area code is assigned three digits from the range of 200-999. The 559 area code falls into the range of 900-999, which includes the rest of California aside from the four most populous cities. This helps manage the growing volume of telephone numbers and creates a more efficient system for communication.
