What state is area code 318?
Louisiana. It covers the same area as 318/457.
Can I still get a 318 number?
Only from recycled stock. 765 of the 786 available blocks are already allocated, so new numbers in the area normally come from the overlay codes (318/457).

318 is one of the most complained-about codes in the country – 956 FTC complaints in the 33 days to 30 October 2026, 47th of 422 ranked codes. Most of those calls are spoofed: the caller fakes a local-looking number because it gets answered more often. Look up the specific number rather than judging by the code.
Which carrier owns 318 numbers?
