About Area Code 318

318 is currently a single-coverage geographic area code with no overlays. This means a 7-digit number in this area code is unique within its rate centers, though best-practice is always to dial the full 10-digit number when contacting a 318 line.
Mobile numbers in 318 are portable: a person who moved away from Shreveport may still carry a 318 mobile number on their device. If you receive an unexpected call from a 318 number, run it through the reverse lookup tool above for the most accurate, free identification.
