Area code 943 is centred on Atlanta, Georgia. We hold 1,470 allocated blocks for it across 35 rate centres, split 45% mobile, 10% landline and 46% VoIP.
The other area codes laid over 943
Area code 943 does not have Atlanta to itself. 4 other codes — 404, 470, 678, 770 — serve the same rate centres, laid over the same ground rather than dividing it. That is an overlay: a new code added when the old one ran out of numbers, covering the same streets. Two neighbours can hold different area codes, so the code says roughly when a number was issued rather than where it sits.
4044,672 blocks, 2 rate centres, mostly mobile
4708,641 blocks, 41 rate centres, mostly mobile
6786,991 blocks, 42 rate centres, mostly landline
7704,130 blocks, 43 rate centres, mostly landline
Each holds its own blocks and its own carrier mix, so a 943 number and a 404 number from the same street can report different line types. Filtering Atlanta by area code needs all 5 of them.
943 is not confined to Atlanta itself: its blocks sit across 35 rate centres, named in the table below.
Georgia is split across 10 area codes — 470, 678, 912, 706, 229, 943 and others. By allocated blocks 943 is the 10th largest of them, holding 3% of the Georgia total.
Where 943 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Atlanta Nw and Gainesvl are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 943 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 943?
Area code 943 covers Atlanta, Georgia. It is not the only code there: 404, 470, 678, 770 are overlays on the same rate centres, so a Atlanta, Georgia number can start with any of them.
Is a 943 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 943 the split runs 45% mobile, 10% landline and 46% VoIP, so VoIP is the most likely single answer.
Which carriers hold 943 numbers?
The largest holders are Onvoy, Powertel Atlanta Licenses, Inc., Teleport Communications America, Llc. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 943 numbers are there?
The code holds 1,470 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 943 covers on the order of 1,470,000 possible numbers — most of which have never been issued to anyone.
