ATLANTA SO prefixes in area code 770
NANPA records 67 assigned NXX blocks to rate center ATLANTA SO in area code 770, 8.5% of the 785 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 9 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (41), PAETEC ITEL, LLC (7), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - GA (5). The earliest assignment on record here is 2001-05-10 and the most recent 2026-01-27. 29 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 470, 678, 943 – overlay codes cover the same geography, so a rate center is served by all of them.
