CALHOUN prefixes in area code 706

NANPA records 14 assigned NXX blocks to rate center CALHOUN in area code 706, 1.8% of the 777 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. 6 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (5), LEVEL 3 COMMUNICATIONS, LLC - GA (3), NEW CINGULAR WIRELESS PCS, LLC - GA (2). The earliest assignment on record here is 2001-05-08 and the most recent 2023-06-02. 10 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 270, 318, 618, 660 – overlay codes cover the same geography, so a rate center is served by all of them.
