The towns inside area code 318
Area code 318 is not a city code. It covers 119 separate rate centres — billing areas, each its own local calling zone. The largest of them are named in the table below.
That matters twice over. A call between two 318 numbers is not necessarily a local call, because they can sit in different rate centres. And a code this wide narrows a subscriber to a region rather than a town.
Louisiana is split across 5 area codes — 318, 337, 504, 225, 985. By allocated blocks 318 is the largest of them, holding 27% of the Louisiana total.
Where 318 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Farmervl is shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

The largest holder, AT&T Wireless, has 16% of the code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 318 number still reports the carrier it started with. Closing that gap needs a live query against the routing database. How line type is derived.

Common questions
Where is area code 318?
Area code 318 is centred on Shreveport, Louisiana and spans 119 rate centres, so it covers a region rather than a town.
Is a 318 number a mobile or a landline?
It can be either, and the digits do not say which. North American mobile and landline numbers share the same ranges, so the answer comes from the carrier holding the block. In 318 the split runs 39% mobile, 47% landline and 14% VoIP, so landline is the most likely single answer.
Which carriers hold 318 numbers?
The largest holders are AT&T Wireless, Onvoy, Bellsouth Telecomm Inc Dba South Central Bell Tel. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 318 numbers are there?
The code holds 5,995 allocated blocks in our copy of the numbering plan. A block is 1,000 or 10,000 consecutive numbers depending on how deeply it has been pooled, so 318 covers on the order of 5,995,000 possible numbers — most of which have never been issued to anyone.
