Find any 318- phone number in Louisiana
The 318 area code is located in the state of Louisiana in the United States of America and is part of the North American Numbering Plan (NANP). This system assigns and administers telephone area codes in the NANP, which includes the United States, its territories, and Canada. This code specifically serves the northern and central parts of Louisiana, covering 40 counties in the area.
It was first established in 1947 as one of the original core area codes, serving the entire state of Louisiana. This code has since gone through several splits and reductions to form what is now the 985, 504, 225, 337, and 651 area codes. 318 is now primarily used for landline numbers in the Shreveport, Monroe and Alexandria areas of the state, while 7 and 9 area codes tend to be used more for mobile phone numbers. It is the only code in Louisiana that is still surrounded by all original boundaries, making it one of the most stable area codes in the NANP.
