The other area codes laid over 770
Area code 770 does not have Atlanta Ne to itself. 3 other codes — 470, 678, 943 — 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.
4708,641 blocks, 41 rate centres, mostly mobile
6786,991 blocks, 42 rate centres, mostly landline
9431,470 blocks, 35 rate centres, mostly VoIP
Each holds its own blocks and its own carrier mix, so a 770 number and a 470 number from the same street can report different line types. Filtering Atlanta Ne by area code needs all 4 of them.
770 is not confined to Atlanta Ne itself: its blocks sit across 43 rate centres, named in the table below.
Georgia is split across 10 area codes — 470, 678, 912, 706, 229, 770 and others. By allocated blocks 770 is the 7th largest of them, holding 8% of the Georgia total.
Where 770 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.

Common questions
Where is area code 770?
Area code 770 covers Atlanta Ne, Georgia. It is not the only code there: 470, 678, 943 are overlays on the same rate centres, so a Atlanta Ne, Georgia number can start with any of them.
Is a 770 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 770 the split runs 29% mobile, 60% landline and 11% VoIP, so landline is the most likely single answer.
Which carriers hold 770 numbers?
The largest holders are Bellsouth Telecomm Inc Dba Southern Bell Tel & Tel, Bellsouth Telecomm Inc Dba Southern Bell Tel & Tel (Bellsouth), Verizon Wireless. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.

The code holds 4,130 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 770 covers on the order of 4,130,000 possible numbers — most of which have never been issued to anyone.
