EASTMAN prefixes in area code 478

NANPA records 9 assigned NXX blocks to rate center EASTMAN in area code 478, 2.0% of the 446 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. 8 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (2), LEVEL 3 COMMUNICATIONS, LLC - GA (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - GA (1). The earliest assignment on record here is 2003-02-10 and the most recent 2024-03-21. 6 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 code 608 – overlay codes cover the same geography, so a rate center is served by all of them.
